 | This is a Miniball robot. It uses a simple 1381 solar engine, a pager motor and a small gearbox from a wind-up toy. The driveshaft is glued to the center of one side of the plastic ball, while the shaft on the other side pivots freely. The solar engine charges from a small solar cell on top of the gearbox/capacitor. When the solar engine discharges, it runs the pager motor/gearbox and causes the whole mechanical assembly to rotate. This throws the robot off balance and makes the ball roll off in a random direction. |
