Here’s a really cool application of 3D printing and robotics by a fellow named [Maundy] – He’s created a very unique kinetic robot which relies on gravity to walk around.
All the electronics are housed in the cylinder as shown above. It can roll freely back and forth by some kind of mechanism inside (not shown), but the beauty of it is, when the cylinder rolls to one end, gravity takes over and the little robot actually flips through the air, reorienting itself onto its other feet.
Due to the flipping nature of the bot, it can even climb over small obstacles with ease – but this one can’t steer, so there’s no threat of them taking over the world. Perhaps with a modification to the control cylinder (turn it into a ball), the robot could orientate itself vertically, and then kind of spin in place in order to steer…
Anyway, you have to see it to believe it, so stick around after the break to see it in action!
