Steam-powered hexapod

This all-mechanical hexapod (translated) was meticulously planned and beautifully constructed. It’s not craning its neck to see what’s ahead. That’s a smoke stack for the steam engine which propels the machine.

Mechanically the legs were the hardest part. That’s only because the steam engine was not built from scratch. It’s a Wilesco D14 which is powered by solid fuel tablets. It puts out high RPM but low power so the gear ratio was set at 286:1 to make the most of its output.

The legs themselves are made of brass rods. These are anchored on one side of a larger gear, with a pivot point that allows the leg to slide vertically. The result is best seen in the clip after the break. As the drive wheel rotates, the pivot point moves the body forward until the foot is lifted by the sliding motion of the rod.
