Sometimes products with no real application can also be interestingly appealing. Such case in point is this self rolling miniball. A weird robotic contraption this has solar panel attached to help a small battery within to be charged by the power of the sun. Belonging to Solarbotics’ BEAM robot family of ‘rollers’, this Jérôme Demers’ project rolls over like a ball when the battery within it attains a sufficient amount of the power kick the motor running. If you have worked out some practical use for the miniball, then follow the instructable and try making your own. Just remember to fit in some solution to get it to a halt because at times you’d want to stop it before the battery gives up. Video of the miniball in action after the jump.
