Drill Powered Walking Machine

Izzy Swan of Think Woodworks is at it again. He likes making things out of wood, and then powers them with a single cordless drill. His latest contraption is a drill powered walking machine. If you have ever tried to build something much simpler than this, say a cutting board for example. You know how much work went into this crazy drill powered walking machine. I almost forgot to mention it can carry up to 370 lbs. Yikes. Video of the build after the break.
