Robots is a draft programming task. It is not yet considered ready to be promoted as a complete task, for reasons that should be found in its talk page.
This page uses content from Wikipedia. The original article was at Robots_(computer_game). The list of authors can be seen in the page history. As with Rosetta Code, the text of Wikipedia is available under the GNU FDL. (See links for details on variance)


The task is to implement a clone of Ken Arnold's turn-based game Robots.

Simple game where its only objective is to escape from a number of robots, which have been programmed to kill the player.
