Video: 15 yr old Phillip working through design of testing rig for new omni-directional ball wheel by James Bruton. We do not have ball wheel 3D printed as yet but do have a rig with Yahboom Super:bit hosting Micro:bit and Android app to control wheel direction and speed. Code for Microbit in video description.
