If you’re thinking about a fairly cool, fairly inexpensive gift for the holidays, take a look at Battle Wheels. These are wheeled robots that are supposed to beat the heck out of each other so their parts fall off, sort of like Rock ‘em Sock ‘em Robots only mobile. I played with the robots with Kasper and he enjoyed pulling the heads off of both Saturnus Guardian of the Kitchen and Wankel Rotary the Enforcer — I forget their names right now, but they have back story.

A much more exciting video.
