(2) Agriculture: In agriculture, robots are now successfully utilized for fruit picking, potato digging etc.(3) Nuclear energy: Handling of radioactive substances in a nuclear power station is an important work done by robots.
Sensors are measuring instruments that measure quantities such as position, velocity, force, torque, proximity, temperature etc.
Though robots are used widely in industries but they are also popular in other fields like agriculture, nuclear energy, fire fighting, mining, undersea exploration, space exploration, medical applications etc.
(1) Industries: Use of robots in industries are very common because they can offer reduced cost of production, increase productivity, improve production quality, and can operate hazardous and hostile environment.
Robots, at industries are classified according to the type of work they perform like Pick- and place robots, point-to-point robots, assembly robots etc.
The dictionary meaning of robot is a mechanical man or a more than humanly efficient automation.
It is an automatic apparatus or device that performs functions ascribed to human beings or operates with what appears to be almost human intelligence.It moves in the way that it was originally programmed, or designed to act.These actions are described as ‘intents’ of its own.If the specification of task changes even slightly the fixed automation becomes incapable of performing the task.It is designed to perform according to one fixed specification.This feature that a robot can be reprogrammed makes the robot a flexible device.Hence, manufacturing systems which use robots are called flexible manufacturing system (FMS) due to this flexibility.Hence robotics involves a scientific study of robots.The study includes design, selections of materials of proper quality for the components, fabrication, study of various motors required for moving the components, design of electronic circuits, computers and computer programming and control of robots.This relieves the human beings from doing such hazardous tasks.(4) Fire fighting and mining: Robots can perform hazardous works like fire fighting to extinguish the fire and in mining operations.
