Robotics is the branch of mechanical engineering, electrical engineering, and computer science that deals with the design, construction, operation, and application of robots, as well as computer systems for their control, sensory feedback, and information processing.
Robot is a real or imaginary machine that is controlled by a computer and is often made to look like a human or animal. a machine that can do the work of a person and that works automatically or is controlled by a computer.
Robots can be autonomous or semi-autonomous and range from humanoids such as Honda‘s Advanced Step in Innovative Mobility and TOSY‘s Ping Pong Playing Robot (TOPIO) to industrial robots, medical operating robots, patent assist robots, dog therapy robots, collectively programmed swarm robots, UAV drones such as General Atomics MQ-1 Predator, and even microscopic nano robots. By mimicking a lifelike appearance or automating movements, a robot may convey a sense of intelligence or thought of its own. These robots have also created a newer branch of robotics.
As mechanical techniques developed through the Industrial age, there appeared more practical applications such as automated machines, remote-control and wireless remote-control.
