Cave Crawler

This build is inspired by the Power Miners theme. The Cave Crawler walks across the cave floor, using its long arm to quickly strike and destroy rocks in front of it.

The walking mechanism is based on Chebyshev's plantigrade machine. The four legs are set in motion by the wheel in the middle that rotates when the vehicle is pushed. The legs move at almost the same speed as the vehicle, creating the illusion of walking. The arm on the back extends when one of its connection points is pushed forward.
