This field includes the wiring, the sensors, and the physical side of the computer inside a robot. The electronics are the 5 senses and the nerves of the robot. They are the way messages get carried from the computer to the robot's limbs, and the way that sensors can send their information to the computer. Programming Programming is telling a robot what to do. Human beings base their choices on their senses, experiences, and the input of the people around them.
Robots have programming to make their choices.
It is possible to program a robot to do anything, after allowing for its physical constraints. It is just very hard to program it to do something. But, of course, robotics can be fun.
