[attachment=26091]
Definition of Robot
Webster:
“An automatic apparatus or device that performs functions ordinarily ascribed to human beings or operates with what appears to be almost human intelligence”
2. Robot Institute of America
“A robot is a re-programmable, multifunctional manipulator designed to move material, parts, tools or specialized devices through variable programmed motions for the performance of variety of tasks”
Technologies that go to make up a robot
Mechanical Engineering
Design of the mechanism.Understanding of the kinematics and
dynamics of the system.
• Electronic Engineering
Design of the actuator and sensor systems.
• Systems Engineering
Analysis and integration of the overall system. Signal conditioning and Control.
• Computer Science
Design of the logic, intelligence or adaptability, networking and
interface.
Robot Characteristics (cont)
Payload is the weight a robot can carry and still remain within its other specifications
E.g. A robot maximum load capacity may be much larger than its specified payload, but at maximum level it may become less accurate, may not follow its intended path accurately, or may have excessive deflections
Advantages & Disadvantages of Robots (cont)
Advantages
Robots have repeatable precision at all times, unless something happens to them or unless wear out
Robots can be much more accurate than human. E.g. New wafer handling robots have micro inch accuracies
Accessories and sensor can have capabilities beyond humans
Can process multiple stimuli or tasks simultaneously.
Disadvantages
Robots replace human workers creating economic problems. E.g. lost salaries, social problems (dissatisfaction and resentment among workers)
Robots lack capability to respond in emergencies, unless the situation is predicted and the response is included in the system. Safety measures are needed to ensure that they do not injured operators and machine working with them
