[prabbit22m] has written an instructable on how to build a radio controlled sphere. The mechanism is fairly simple, with one drive motor, one servo and a gyro for stability. To turn, the servo shifts the center of gravity off to one side. You can see that the system works pretty well in the video above. If it didn’t have that gyro, it would be insane, believe us, we’ve done our own experimenting. If you like this, but want more features, check out this one that has a camera and takes pictures wherever it goes. We can’t forget Swarm either. The autonomous swarm of robot spheres. Of coarse [prabbit22m] might have the best idea of all. Dress it up as a regular ball to mess with people.
