Spine Crawler is a walker Bot that uses a modified Jansen linkage for its legs. The legs are one TPU part, with flex points in critical locations to produce the desired motion profile.

The hammer uses a Grashof linkage, which is a 4 bar linkage that allows continuous rotation. Additionally, the mechanism is designed with a quick return ratio, meaning that the hammer swings faster in the downstroke and has more torque on the return to assist in self righting.
