Tamiya Rolling Robot (2-Channel IR Remote Control) 70267

This Rolling Robot assembly kit features one big hemispherical wheel, one for the left and right side. The Rolling Robot is operated easily by the included infrared remote controller after assembly. Additionally, the robot employs the use of heavy parts such as gearbox and batteries (batteries sold separately) which work as the center of gravity and move like a ball by transferring that center of gravity.
