CarBot lets you settle those grudges with battle mode
 

If you prefer your robots a little more terrestrial, there's Desk Pets' CarBot, a buggy that can do tricks, navigate mazes, and race with -- or fire on -- your buddies. The cars can be controlled by a free app installed on any iOS or Android Device, and allow up to four players to duke it out in multiple play modes. For mayhem lovers the most popular may be "battle," allowing you to fire on rival cars to disable them, along with a personality mode for freestyling and a drift 'n' race option. There's even a maze mode, in which the tiny wheeled bots use their infrared sensors to avoid objects with "military precision," according to the company. The built-in battery will give you 25 minutes of playtime for every 45 minutes of USB-based juicing, and each CarBot will set you back $30. Check out the PR and video after the break to let the rolling deathmatch commence.
