P-Robots is a game played by up to four programs which control a simulated battle robot. Programs are written in Pascal.
In 1988 the first version of P-Robots was released as shareware for DOS by David Malmberg. The Turbo Pascal source code was only available to registered users. P-Robots was relicensed as freeware in 1994. Around 2008-2009 the code was ported to Free Pascal by Marco Borsari as the Stout edition, allowing the code to support contemporary operating systems.
The arena is 1000×1000m with the origin at the bottom left. 0° is to the right, increasing anti-clockwise.
