Topo is a robot designed in the 1980s by Androbot Inc., for the consumer and education markets. It was programmable via Apple II and there was also a user made program for the Windows 9x operating systems. The programming language allows the robot to perform a set of geometric movements, to move about a room and perform tasks. It was like a servant robot, although it did not truly meet the requirements of a robot, as it had no sensors to use to receive input and then make decisions accordingly.
