I believe I bought my copy in college, between 2002 and 2006. It was a hardcopy manual, and a CD as I recall it. The premise is that some workers on a space station (I'm pretty sure it was a space station... completely sure that the setting was not on Earth, but a group of isolated workers) have gotten bored, and compete in programming contests with small robots on the station. The robots had limited area on which to place components in a grid setup, whereupon you'd wire the components together. I remember there were various tasks, generally solo, things like navigating a maze (I know it had one of these... I think with mouse-sized robots?) or running around and picking up objects. There were a few competitive tasks, one involving kind of a battle-bots setup where rather than programming the robots, you got a joystick interface for them.
The game came with a manual that had ring binding (the plastic spiral kind) but I remember that they also had online documentation in the (then unfamiliar to me) wiki format, where people could offer edits. I remember there was also a modding community, with someone providing an additional weapon for the arena combat that was essentially a handgun duct-taped upside-down on the robot.
The graphics were 3D, I think simple textures with more or less flat shading. Interface was a mixture of mouse and keyboard. I remember being really enthused about it because it seemed like there were immense possibilities, but I got bogged down in the difficulty of wiring the components together. I remember being particularly frustrated with the maze one because I understood the right-hand rule to navigate a maze, but couldn't figure out how to translate that to the components.
