Part A
Define the term robotics.
Answer
Robotics is the multidisciplinary branch of science and engineering that deals with the design, construction, operation, and application of robots, as well as computer systems for their control, sensory feedback, and information processing.
Define automation.
Answer
Automation is the technology by which a process or procedure is performed with minimal human assistance. It involves the use of control systems, such as computers or robots, and information technologies to handle different processes and machinery in an industry to replace a human being.
