Introduction: Hopping Robot Leg

About: I am an American teaching English at Shangluo University, Shaanxi. I like making machines that do interesting but fairly useless things - I call them Quixotic Machines.
This is a continuation into the curious behavior of wheel motion converted into leg walking, hopping and skipping motion.
This is a video of a leg (short section of fishing pole) attached to a pivot point and attached to a motorized toy truck wheel by a short arm. The number of possible attachment points and lengths of arms and legs is huge and the video shows a single configuration that I thought was interesting, funny and kind of unexpected.
Please see my Simple Robot Leg instructable (https://www.instructables.com/id/Build-a-Simple-Robot-Leg/) for details on how to build the test tether or platform I am using here.
