Izzy Swan loves to make machines that are driven by an ordinary battery-powered hand drill. He’s made a band saw, a lawn mower, and a mini bike this way.
His latest challenge was inspired by Theo Jansen’s famous kinetic sculpture Strandbeest. Swan’s walking machine uses the rotary motion of a 20 volt drill to move two actuated legs forward, pushing a little cart. It’s like a Segway, but way cooler. It can hold up to 370 pounds and move for a mile on a full battery charge.
