It may bear closer resemblance to an upright dog than a human (check out those ears!), but POLYRO here is the least frightening example of a do-it-yourself robot that we've seen to date. We're not sold on the humanoid's name as an acronym (oPen sOurce friendLY RObot), and the instructions and assembly photos are rather hit or miss, but this rollin' rover definitely scores some points for looks. Prepare to get down and dirty with a jigsaw, drill press, and "safety equipment," before the latest addition to your family is ready to roll across the living room floor on its iRobot base. Instructables has posted a full shopping list, including a 10.1-inch netbook, ROS (Robot OS), and a Kinect.
