The keyboard robot can use the keyboard of another computer –

A keyboard robot is a device that allows one computer to operate the keyboard of another computer. It also allows a computer to control its own keyboard. It can even be used to control a network of computers if a multiplexer is added.

The Keybot can do many things that cannot be done any other way. It can do something as simple as set the CMOS settings during a power up of a computer. It can do something as complex as linking many computers & programs together for artificial intelligence. It does not require knowledge of those computers nor the program languages used.

This report includes all the information needed to build your own Keybot. It also includes control software written in QBASIC. The Keybot project is inexpensive to build but it requires you to have some electronic knowledge and soldering ability.
