Michael Overstreet and some friends have created these fun Turtle Shell Robot Racers, using a Makerbot 3D printer, and as you will see in the video below, they are controlled using various smartphones.

Unfortunately there really isn’t very much information on them at the moment, so we will have to make do with the video below for now.

Michael will apparently be releasing more information on these fun Turtle Shell Robot Racers, including a website and some details on how they are controlled.
