The correct answer is: B. Pick-and-place manipulator.
A robot is a machine that can be programmed to carry out a series of actions automatically. Robots are often used in manufacturing and industrial settings, but they can also be found in other areas such as healthcare, education, and entertainment.
The Robot Institute of America (RIA) defines a robot as “a reprogrammable, multifunctional manipulator designed to move material, parts, tools, or specialized devices through variable programmed motions for the performance of a variety of tasks.”
Of the options given, only a pick-and-place manipulator meets this definition. An automobile is not a robot because it is not programmable. An artificial hand is not a robot because it is not a manipulator.
It is important to note that the RIA’s definition of a robot is not the only one that exists. Other organizations, such as the International Federation of Robotics (IFR), have different definitions. However, the RIA’s definition is widely used in the robotics industry.
