Halloween is a scary time for the little ones. The Rovin’ Pumpkin’ is a simple robotic pumpkin, and a close cousin of the Snap-O-Lantern. Silently, it sits on your porch– camouflaged amongst the humble squashes.
It’s dark, they can barely see through their injection molded Spiderman masks, but it’s all worth it for the candy.
The little pumpkin was disemboweled from the bottom and its guts were replaced by a simple robot. The Rovin’ Pumpkin’ started out as a particularly attractive green-veined pie pumpkin. It was carefully carved out from the bottom to leave a shell that could sit on top of the robot platform.
Three Lego wheels provide this base with one attached to a continuous rotation servo that provides the motion. The device is powered by 3 AAA batteries and powered by an Atmel ATtiny2313 microcontroller. For added terror there are two green LEDs that act as ghoulish eyes.
