Unlike computers, robots can move around and interact with the world much like a player can. They can not interact with external components, however! If you need to communicate with a computer or other robots, use a Wireless Network Card or create some low-level protocol using redstone signals via a Redstone Card, for example.
Robots are built by placing a Computer Case in an Assembler.
