Microprocessor based robotics arm

Microprocessor based robotics arm Abstract Robotic arm has become popular in the world of robotics. The essential part of the robotic arm is a programmable microprocessor. The microprocessor based brick capable of driving basically three stepper motors design to form an anthropomorphic structure. The first design was for experimental use on a human-size industrial robot arm called PUMA 560 which stands for Programmable Universal Machine for Assembly. This human size robot was used to explore issues in versatile object handling and compliance control in grasp actions it was done in Bejczy city in the Jan, 1986. This paper explains the method of interfacing the robotic arm stepper motors with the programmed 8051-based microprocessor which are used to process and control the robot operations. We have employed the assembly language in programming our microcontroller of the microprocessor. A sample robot which can grab by magnetizing and release small objects by demagnetizing is built for demonstrating the method explained. 1. Introduction A robotic arm is a robot manipulator which is programmable and its functions are almost similar to that of human arm. The links of such a manipulator are connected by joints allowing either rotational motion or translational displacement. Kinematic chain can be formed by the links of the manipulator. The business end of the kinematic chain of the manipulator is called the end effecter and it is analogous to the human hand. The end effecter can be designed to perform any desired task such as welding, gripping, spinning etc., depending on the application. The robot arms can be autonomous or controlled manually and can be used to perform a variety of tasks with great accuracy. The robotic arm can be fixed or mobile (i.e. wheeled) in the nature and can be designed for industrial or home applications. 2. Robotic Arm The word robotics, the meaning and the study of robots was done by a famous foreign scientist Isaac Asimov. Robotics is a branch which involves elements of mechanical and electrical engineering in it, as well as control theory, computing and now artificial intelligence in it by which we can implement it in the different fields. According to the Robot Institute of America, â€Å"A robot is a reprogrammable, multifunctional manipulator designed to move materials, parts, tools or specialized devices through variable programmed motions for the performance of a variety of tasks†. The way in which we are going to use robotic term in the form of arm is called as robotics arm. In order to perform any useful task the robot must interface with the environment, which may comprise feeding devices, other robots, and most importantly people. As the robot with which we are going to deal with work as arm and is therefore known as robotic arm 3. Types Of Robotic Arm There are various kinds of the robotic arm available in the market for the different tasks these are as follows. i. Cartesian Robot / Gantry Robot. ii. Cylindrical Robot. iii. Spherical Robot / Polar Robot. iv. SCARA Robot. v. Articulated Robot. vi. Parallel Robot. 4. Block Diagram For Robotic Arm The method employed in designing and construction of the robotic arm is based upon the operational characteristics and features of the microcontrollers of the microprocessor, stepper motors, the electronic circuit diagram and most importantly the programming of the microcontroller of the microprocessor and mainly the stepper motors. This work is able to successfully accomplish the defined functionality means it defines all the functions of the robotic arm. A sample robot which can rotate, magnetize an object, lower and raise its arm, by being controlled by the 8051 microcontroller of a microprocessor is built successfully and it was named as robotic arm. The 8051-development board is soldered and it used the required procedure for the correct operation of the controller. The 8051 development board has been interfaced to the stepper motors such that the anthropomorphic like structure can be controlled from the buttons at the base of the structure which is robotic arm. These buttons help to control the whole system of the robotic arm. These four buttons have the uncommon task from each other which is explained as follows. On/Off The ON button puts on the system while the OFF button puts off the system. This is only the task allotted to them just to ON and to OFF the robotic arm. Start/Stop The START button starts the initial movement of the whole arm from its reset point, while the STOP button takes the arm back to its reset button after completion of its movement applied for the required task. Right-Left/Left-Right When this button is switched to the RIGHT-LEFT part it causes movement from right to left, while the LEFT-RIGHT part causes movement from left to right. It is used only for the right and left movement. Rotation Of 180/90 When the button is on 180, it causes a rotation of 180 degree of the base stepper motor, but when put on 90 degrees, it causes rotation of 90 degrees. It means it is used for the 90 and 180 degree rotations. 5. Mechanical Structure Of The Arm For the construction of any kind of the robot we must have any kind of the idea over which we have to work for its construction. Same is the case of the robotic arm for its construction we need its mechanical structure. In constructing our robotic arm, we made use of three stepper motors and gears since our structure is a three dimensional structure. A typical prototype that we employed for the construction of our robotic arm. There is a stepper motor at the base of the arm, which is used for circular movement of the whole structure for the easiness of the task; another stepper is at the shoulder which allows for upward and downward movement of the arm again used according to the task given to the robotic arm; while the last stepper motor is used at the wrist which allows for the picking of objects by the magnetic hand. 6. Robotic Arm Design Process It includes various points related to the designing of the microprocessor based robotics arm. All those points which explain them are as follows: Defining The Problem i. Identifying the purpose of a construction. ii. Identifying specific requirements. A community wants to construct a robotic arm. Design and build a prototype device which could satisfy this need. Design and build a prototype device which could satisfy this need. You need to determine what problem you are trying to solve before you attempt to design and build a robotic arm to solve a problem. Researching And Designing i. Gathering information. ii. Identifying specific details of the design which must be satisfied. iii. Identifying possible and alternative design solutions. iv. Planning and designing an appropriate structure which includes drawings. Creating A Prototype i. Testing the design. ii. Troubleshooting the design. Building Your Robot Construction work can now begin. Here are some sites that help with: i. Structure. ii. Gear combinations. iii. Arm mechanisms. iv. Placing sensors. v. Hints and tricks. vi. The Art of LEGO Design by Fred Martin an excellent resource for building very strong structures. Programming And Testing Your Robot Now it is time to program your robot. This can be achieved in many different ways. Use can achieve rudimentary intelligence in your robot by using only relays, potentiometers, bump switches and some discrete components. You can increase complexity in intelligence in your robot by adding more sensors and continuing in the same vein of using hardwired logic. By introducing a more sophisticated control element, the microprocessor, you introduce a significant new tool in solving the robot control problem. Evaluating Your Robot i. Evaluate the design. ii. Evaluate the planning process. As building and programming work progresses, and the design begins to take shape, you will automatically carry out tests on the design. You will also need to complete systems tests at various stages of the construction. If any of the tests show that you have failure in a joint, or that part of your structure is not meeting specifications, then you will have to make modifications in your plan. When building and programming is complete, the entire project must be tested to see if it does the job for which it was designed. An evaluation needs to then be written. This should be a statement outlining the strengths and weaknesses in your design. It should describe where you have succeeded and where you have failed to achieve the aims set out in the specifications. 7. Overall Arm Design The two arms used both have six degrees of freedom, and are mounted on the humanoid robot cog. The arms are mirror image of one another. The kinematics of the arm is designed to be similar as that of the human arm. There are two joints each at shoulder, elbow and wrist although the axis of the first elbow joint is coincident with the co-axes of the shoulder joints. The arms has length same as that of the length of the human arm. 8. Market Applications Of Robotics Arm Applications of robotic arm are very effective in the market world. There are various fields where there is a deemed need of the robotic arm these can be explained as follows. Automotive Robotic arm can be used in different ways in the automotive field. i. Power train Control ii. Body Electronics iii. Driver Information Systems iv. Chassis v. Safety vi. Automotive Networking Consumer Robotic arm can be used in different ways in the consumers. i. Mobile Consumer Electronics ii. Home Electronics Industrial Robotic arm can be used in different ways in the industrial field. i. Factory Automation ii. Building Control iii. Metering iv. Medical v. Point of Sale/Kiosks vi. Home Appliances Medical Robotic arm can be used in different ways in the medical field. i. Home Portable ii. Diagnostics and Therapy iii. Imaging iv. Intelligent Hospitals Networking Robotic arm can be used in different ways in the networking field. i. Network Security ii. Home and SOHO Networking iii. Network Storage 9. Future-Scope The scope of this work for manufacturing of robotics arm involves confirming the 8051 micro-controller of microprocessor. Input/output (I/O) signals are compatible with that of the robotic arm stepper motors and testing of the robots motor signals through programming the 8051 microcontroller of the microprocessor. Assembly programming is used to develop the programs for the EPROM 2732 on the 8051 micro-controller of the microprocessor platform that takes robots motor signal as I/O and controls the robot operation programmatically. We have assumed that after figuring out the interface issues for the Robot with the 8051 microcontroller, the same knowledge can be extended to make very complex robots with enhanced functionality. With the technique used in the manufacturing of the robotic arm we can also make other robots for the different tasks. Conclusion Finally from this topic we can conclude a robotic arm is an instrument by means of which we can do any kind of the task and use it in the way in which manner we want to solve the task. The controlling software used in this robotic arm can be general for any kind of robot arm and set of sensors. This paper introduces a set of design principles which seek to reduce robotic applications design and implementation time so reducing the errors present in any practical implementation as well. Experiments show that the solution presented in this paper, although its limitations, allow the robotic applications designer to save development time while keeping the overall complexity low. There exists open-source applications which handle similar problems but they are not well fitted for small control applications. We have learnt that because of limitations in the programming language used to develop the application and the final application itself is highly sensitive to implementation issues. Also , to completely verify the design principles it would be necessary to evaluate the effort required to design a control application for multiple and heterogeneous platforms.

Brain Busters: The History of Lobotomy and its Application to Neuroscience :: Biology Essays Research Papers

Brain Busters: The History of Lobotomy and its Application to Neuroscience "It seems possible that with additional experience and a minute study of the pathologic changes seen in the brain, the knife may be the means of restoring to reason many cases now considered incurable" --Emory Lamphear (1895) (5) In 1847 an Irish workman, Phineas Cage, shed new light on the field of neuroscience in a rock blasting accident which sent an iron rod through the frontal region of his brain. Miraculously enough, he survived the incident, but even more astonishing to the science community at the time were the marked changes in Cage’s personality after the rode punctured his brain. Where before Cage was characterized by his mild mannered nature, he had now become aggressive, rude and "indulging in the grossest profanity, which was not previously his custom, manifesting but little deference for his fellows, impatient of restraint or advice when it conflicts with his desires" (1) according to the Boston physician Harlow in 1868. However, Cage sustained no impairment with regards to his intelligence or memory (1). This incident provoked scientists to ask the question, "can alteration of the brain structure lead to differences in personality?" and if so, then "are there specialized reg ions of the brain responsible for the function of different elements of our personal character?" Thus, completely by chance, the foundational discoveries for the development of frontal lobotomy were laid. Beginning in the late 1800’s, experimental surgeries involving various incisions slicing or destroying parts of the frontal cortex were performed on a variety of subjects in an effort to produce a calming effect in their behavior. In 1935, Dr. John Fulton presented the results of his research on a pair of chimpanzees at a conference for neurology. Fulton had "removed completely the frontal lobes" (4) of the chimps and observed that after the surgery they appeared significantly calmer than before the operation as he was unable to "generate experimental forms of neurosis in the animals"(1). Attending this conference were two neuro-scientists, Egas Moniz and Walter Freeman, both of whom would become major figures in the practice of lobotomy. Egas Moniz was particularly fascinated by the idea of the behavioral changes in Fulton’s chimps and posed the shocking question, "If the frontal lobe removal prevents the development of experimental neurosis in animals and eliminates frustrational behavior, why would it not be possible to relieve anxiety states in man by surgical means?

Modern Christian Movement

Christian Fundamentalism is both a movement and a code of rules, referring to the adherence to the religion and Biblical teachings (http://www.sullivan-county.com/news/index.htm, 2003). Nowadays, the term is often corrupted to describe extremists and terrorists, who attack multiculturalism, democracy and the basic concepts of family planning. The present paper is designed to discuss the movement and the underlying doctrine in details and compare it to the similar Islamic and Judaist religious movements and trends. The Modern Christian Movement emerged in the beginning of the 20th century in response to modernism, industrialization and the following reformations of social life towards democracy (Appleby et al, 2003). â€Å"The five â€Å"fundamentals† of Christian belief that were enumerated in a series of 12 paperback volumes containing scholarly essays on the Bible that appeared between 1910 and 1915. Those included: 1) Biblical inerrancy; 2) The divinity of Jesus; 3)The Virgin Birth; 4) The belief that Jesus died to redeem humankind; 5)An expectation of the Second Coming, or physical return, of Jesus Christ† (www.sullivan-county.com, 2003). Furthermore, the tracts contained the criticism of technological progress and modern theology and insisted upon the return to the initials, i.e. to the first century, when original Christianity was spreading.   The whole Bible was declared inerrant, in contrast to the other Christian movements, which refuted certain parts of the Gospel. Furthermore, fundamentalists had true hostility to those who didn’t share their beliefs up to the last point, as they alleged there was nothing redundant or useless in the Bible (Appleby et al, 2003), as the scriptures should have been viewed as instructions rather than edifying stories and narratives. The followers of the movement also believed in the sixth-day Creationism and therefore rejected the whole evolutionary science. More importantly, they asserted   that Bible should not have been interpreted, as it had to be understood literally, without searching any mystic contexts, as the scriptures were written specifically for ordinary people’s understanding (Appleby et al, 2003; Armstrong, 2001). Furthermore, fundamentalists prioritized faith over virtuous lifestyle, whereas the latter was nevertheless to correspond with the exact fundamentalist teachings. It also needs to be noted that fundamentalists viewed human being as basically sinful and violent: â€Å"Because Calvin, Luther, and Augustine all see humans as â€Å"depraved† and â€Å"born into sin† produced a very negative outlook on humanity. Also their idea of the â€Å"elect† creates an attitude that they are somehow â€Å"chosen† above all others. This puts them at odds with â€Å"mainline† or liberal Protestant churches that reject the Augustinian notions of human depravity† (www.sullivan-county.com, 2003). The history of the movement itself is also interesting and controversial. In the early 20th century, the disciples of the fundamentals began to establish churches and denominations in the United States and United Kingdom (Appleby et al, 2003). In 1910, the northern Presbyterian Church proclaimed the five aforementioned principal pillars. In 1919, the World’s Christian Association was found, and W.Riley agreed to head it. In 1920, the term â€Å"fundamentalist† was first used by Curtis Lee Laws, but the contemporary fundamentalists perceived the term ambivalently, as it sounded like a conceptually new religious movement (http://mb-soft.com/believe/text/fundamen.htm, 1997). Due to the penetration of liberalism into a number of American churches, fundamentalists began to criticize widely the transformation and peculiar ‘democratization’ of Baptist and Protestant churches. Furthermore, they rejected and even attempted to curb the contemporary efforts to re-interpret and reformulate the biblical teachings, and were themselves most consistent with the content of the King James Bible, published in 1611(Armstrong, 2001; Appleby et al, 2003). â€Å"Church struggles occurred in the Methodist Episcopal Church, the Protestant Episcopal Church, and even in the southern Presbyterian Church, but the grand battles were fought in the northern Presbyterian and northern Baptist denominations. Machen was the undisputed leader among Presbyterians, joined by Clarence E.Macartney† (mb-soft.com, 1997). Consequently, a number of organizations were created on the basis of the reformed Baptist and Presbyterian churches, which began to utilize the five fundamentals: the Fundamentalist Fellowship (1921), the National Federation of the Fundamentalists of the Northern Baptists (1921) and the Baptist Bible Union (1923). The unions developed their own policies in such issues as ordination of clergy ad education, and a number of particularly enthusiastic preachers denied the importance of literacy and declared Bible as their only ‘reader’ in the course of training (Armstrong, 2001; mb-soft.com, 1997). Approximately at the same time the fundamentalists began to interfere with the policies of public schools, specifically, with their curricula which included Darwinian evolution as a mandatory subject (Appleby et al, 2003). Since the 1940s, the fundamentalists split into two groups, the first one accepted the term â€Å"fundamentalism† and began to run to some extent separatist policies, whereas the second camp regarded the term as humiliating and positioning the followers of the movement as narrow-minded fanatics. The latter group, as one can understand, wished to expand the influence over Protestant churches and therefore declared their teaching as â€Å"evangelical†. This group soon ‘softened’ their hard-line Christian belief and gradually accepted the contemporary liberal ideas, expressed by a number of Protestant Church executives. Towards the late 1970s, there was a peak of the fundamentalists’ popularity, as   during Ronald Reagan campaign (Appleby et al , 2003), they were able to find answers to the most troublemaking issues like economic and social crises (in fact associated with the Vietnam War, but the adepts of the movement manipulated with the fall of the population’s moral and optimism and stated the contemporary mentality was erroneous). â€Å"They identified a new and more pervasive enemy, secular humanism, which they believed was responsible for eroding churches, schools, universities, the government, and above all families. They fought all enemies which they considered to be offspring of secular humanism, evolutionism, political and theological liberalism, loose personal morality, socialism and communism† (mb-soft.com, 1997). Thus, they employed the most powerful PR tools to influence public consciousness and arranged a number of protest actions, including the picketing family planning centers, certain education institutions and scientific laboratories in attempt to undermine the reputation of the mentioned organizations (Armstrong, 2001). Such religious activists as Jerry Falwell, pat Robertson and Hal Lindsey appeared on TV-screens as often as very popular politicians or the president and continued to encourage citizens to refuse from technological advancements, democratic ideology; the most radical fundamentalists even tried to curb immigration and force foreigners of different faith to leave the United States. The Fundamentalist Movement of the 1990s and the new millennium is still strong, but the organization has become much more ‘secluded’. Nowadays, the American Academy of Arts and Sciences has launched a new project that encourages scholars in the United States and around the world to study fundamentalism (http://religiousmovements.lib.virginia.edu/nrms/fund.html, 1998). They also theorized the religious doctrine and outlined the its basic characteristics, which include the manifestation of religious truth which must not be secreted, religious idealism as the major aspect of fundamentalist identity and demonization of any movements which diverge from the doctrine. Furthermore, â€Å"fundamentalists envision themselves as part of a cosmic struggle; they seize on historical moments and reinterpret them in the light of this cosmic struggle; they envy modernist cultural hegemony and try to overturn the distribution of power† (religiousmovements.lib.virginia.edu, 1998). Appleby also discusses the major characteristics of the organized movement and stated and its primary course is the increase of the popularity of Christian religion. Furthermore, the members of the movement are selective and reject specific aspects of technological progress rather then modernity in general; the organization itself has â€Å"an elect or chosen membership; sharp group boundaries; charismatic authoritarian leaders and mandated behavioral requirement† (ibid, 1998). As one can understand, Christian fundamentalism has a lot in common with Islam and Judaism, especially in terms of the structure of the movement. For instance, both Orthodox Judaist and Islamic fundamentalist movements have the same organizational characteristics and regard themselves as the participants of a cosmic struggle. This trend, however, is not very notable in Judaism, whereas the most hard-line Muslim leaders (of radical organizations like al-Qaeda) wage true war against otherwise-minded, and, similarly to Christian fundamentalists, demonize anyone who dares challenge the teachings from the Holy Scriptures perceived as central. Judaism has always been less radical and its fundamentals are more related to the controversy over the origin of the Torah, which, as most Orthodox Judaists hold, derives actually from God rather than from humankind (Armstrong, 2001). Judaist Fundamentalism also includes â€Å"Laws of Rabbinic decree to better enforce Torah law (e.g. the prohibition of eating/cooking mixtures of milk and poultry); these laws are held to be created by the rabbis and are divinely inspired† (Armstrong, 2001, p. 385) and observes Rabbeinu Gershom’s prescriptions concerning the ban on reading letters, addressed to another person, the possibility of divorcing a female without her compliance and the regulation of eating habits. Islamic Fundamentalism refers to Sunni Islam, which recognized the Koran, Haddith and Sunnah and accordingly rejects the Shi’a laws. Similarly to the Christian Fundamentalism, the corresponding Islamic teaching includes the notion that â€Å"the problems of the world stem from secular influences. Further, the path to peace and justice lies in a return to the original message of Islam, combined with a scrupulous rejection of innovations† (Armstrong, 2001, p. 396). Technological progress is also partially rejected in the Judaist Fundamentalism – for instance, the Torah teaches that human face should not touch blade, that’s why Orthodox Jews avoid using razors and wear long beards. On the other hand, the Christian Fundamentalism has one unique feature, Messianism, which is not emphasized in the other two doctrines, as most Judaists do not view Christ as an influential religious person, whereas the concept of God’s son is absent is Islam. As one can understand, fundamentalism is to great extent synonymous to conservatism. Nevertheless, it is important to remember that the contemporary fundamentalist movement are based not purely upon the religious doctrines, but also on the aspects of PR, promotion and, if necessary, violence and compulsion. Furthermore, all of them enclose considerable restrictions upon human daily activities, – in Islam, for instance, practically all daily routines have certain algorithms; moreover, all of them challenge humanism and the principles of individual freedom, imposing personal responsibility and accountability to society or community (especially in Judaism) instead.

Free Essays on What It Takes

What it Takes Perhaps more than at any other time in history, today’s parents are concerned about the future of their children. They want a child who will be happy, caring, and compassionate (Christopherson 3). A parenting style choice can mold a child to be this way or to be completely opposite. Parenting style captures two important elements or parenting: parental responsiveness and parental control (Darling). Parental responsiveness is how well parents respond to their children’s needs and demands. Parental demanding ness is how well parents assert disciplinary efforts and how well they supervise. Categorizing parents according to whether they are high or low on responsible demanding ness and responsiveness creates a typology of four parenting styles: indulgent, authoritarian, authoritative, and uninvolved (Darling) Of these styles, authoritative parenting is the most effective. In this style, parents are highly demanding and responsive. â€Å"They monitor and impact clear standards for their children’s conduct. They are assertive but not intrusive, but not intrusive and restrictive. Their disciplinary methods are supportive, rather than punitive† (qtd. in Baumrind 162) (Darling). There are several contributing factors that lead to effective authoritative parenting. It is not easy and takes an abundance of time as well as patience and critical thinking. Authoritative parents focus on giving clear appropriate commands. By doing so, children know that parents mean business. A clear command is a simple imperative sentence. It is not asking a favor, sending an invitation, asking a question, or proposing a threat (Chidekel 119). A clear command is simple: â€Å"Pick up your toys† is an example. Its meaning is simply clear and direct. From this children will gain the knowledge of power of authority. Most children want to belong to a peer group, but promoting the social- skill to do so is a parents task (...

Plan Development for a Major Health Care Facility Essay

Plan Development for a Major Health Care Facility - Essay Example The main aim of business plan is to oversee the implementation of a project based on good decision making, proper planning procedures and methods that eventually will lead to full completion of a project to all parties’ satisfaction. This paper is aimed at establishing a business plan for a major health care facility to its full functionality. The actual project here is a business plan of a major health care facility. For a successful completion of the project, there are many considerations, obstacles as well as opportunities that all have to be looked at before and during the project implementation. Unlike other projects, health care facility requires special attention due to the nature of its work hence it needs more expertise in its project planning. The plan should put in consideration many factors among them; that healthcare facilities depends on continues operations with no tolerance to disruptions, in terms of its construction it will require unique waste streams since chemicals might be involved within its wastes, there is need for provision of intense energy and water use within its surroundings due to the nature of the activities within the healthcare, there should be provision for infection control which should be unique on its own and lastly but not least, indoor air circulation is of importance and hence should be considered in the business plan for healthcare project. These special specifications differentiate a healthcare plan to that of a normal business plan. Any project that is to be consisted within a healthcare facility should fully be planed for and evaluated before its implementation. Existing research has shown that in a period of about last five years, there indeed has been an increase in healthcare projects development to almost 50% as compared to the previous years. This rapid increase has mainly been attributed to the need for new and developing technological innovations in the healthcare sector, aging populations as well as fa cilities, the need for new standards of care and a considerate reimbursement and financing environment. All these have contributed to the witnessed introductions of various projects to the health sector. This intern has brought the need to come up with business plans so as to attain the healthcare objectives with less challenges. The market analysis has shown that indeed there is more need for effective service integration and healthcare management especially for new enrollees within the healthcare sector. This is attributed to the fact that majority of new enrollees are soon to be non-disabled adults and this is a critical fact to the health sector since it’s worth noting that the disabled and dually eligible populations are much more costly and hence stand to benefit more from effective healthcare system. Market analysis has shown that there has been a high rise in the resent years of various special cases in the health sector that indeed have called for business plans to h elp in projects integrations in the health sector. Such like programs include; perinatal conditions that have played a big role in maternal and child health care, Chronic conditions, smoking complications and obesity among others. These complex health matters have brought about the need for establishment of more healthcare facilities and this has called for the need for project planning since healthcare

Pertuzumab - Literature review Example This is enabled by the F-10 binding to the chimeric of the IgGI that largely affects epidermal expansion. However, during the extraction process, pertuzumab undergoes certain stages. First, through the dimerization process that facilitates epidermal growth, HER signaling routes are activated. It implies that the HER2 is mixed with toxicants and other variants that are found in the monoclonal antibody (MAb). The cloning process, thus, occurs during the inhibition of tumors through HER dimerization. Contrastingly, the extraction process should integrate both the structures of extracellular domain and the epidermal growth factor (EGF) that is instrumental in sustaining the function of pertuzumab (Franklin et al., 2005). Another mode of extraction is through the use of ErB2 that reduces higher metastatic potential and tumor growth rates via therapeutic approaches. Purification is the last process of obtaining a complete dosage of pertuzumab and is characterized by the asymmetric unit of varying domains. The molecular replacement is equally interrelated with the monoclonal antibody pertuzumab that is crystallized for solubility purposes and creation of bonded modules. Overall, the management of cancerous cells requires the inclusion (EGF) antigens that are compatible with the individual receiving treatment (Jatoi & Kaufmann,
