CROBOTS is a game played by up to four programs which control a simulated battle robot. Programs are written in a subset of the C programming language.
In December 1985 Tom Poindexter released CROBOTS as shareware. The distribution included a DOS binary with source code in C available to registered users. In 1989 David Wright released a port for the Commodore Amiga. In 2013, the source code was released under the GPL License.
Robots are damaged by collisions or when a missile explodes within 40m. A robot is destroyed when it reaches 100% damage. A robot's maximum speed is 100.
The maximum range for missiles is 700m. Only two missiles can be in the air at any time.
The arena is 1000×1000m with the origin at the bottom left. 0° is to the right, increasing anti-clockwise.
- CROBOTS 3D -- allows robots to be able to be programmed with the same code, and adds 3D graphics to combat.
