Discuss the functions of key components in Robots?

Explanation

The robotic system mainly consists of sensors, power supplies, control systems, manipulators and necessary software.
Most robots are composed of 3 main parts:
(i) The Controller also known as the "brain" which is run by a computer program. It gives commands for the moving parts to perform the job.
(ii) Mechanical parts motors, pistons, grippers, wheels, and gears that make the robot move, grab, turn, and lift.
(iii) Sensors to tell the robot about its surroundings. It helps to determine the sizes and shapes of the objects around, distance between the object, and directions as well.
