From the publisher's website:

Four robots move in a warehouse. As they have no brakes, they must rely on obstacles such as walls and other robots to to stop. Once stopped, they use nozzles to move in a direction away from that obstacle, allowing them to ldblquote turnrdblquote. From time to time, they receive a request to move to one of the 17 targets in the warehouse and they rely on the players to provide them with instructions to move to the targets. Each turn, a player draws a chip to determine the next target and the robot that must reach it. The players search for the shortest moves to the target, using one or more of the robots. The player who finds the shortest route receives the chip as a reward. The player who takes the most chips, is the winner! Any number may play this game, making it a great party game. There have been 2 versions of the game published. The original and a second edition with diagonal walls and a black robot. The currently available version has no diagonal walls and an extra silver robot. The two are compatible with each other such that the boards from the game may be used together - though only four at one time, of course.
