This is my updated version (some 5 decades later).

The spinning flywheel is geared down by about 70:1 to a cam which pushes the legs up and down. When the left leg goes down, the body is lifted up and the gyroscopic effect causes the it to precess to the left, but when the right leg comes down, it precesses back to the right, and voila, it walks!

Especially if you have a 300' driveway. This shows me clearing snow from a gravel driveway that's already been partially compacted.

However, it is a pretty fun mechanism for, say, trapping errant ping pong balls.

And then...they aren't! This 3D printed "Walk the Plank" style mousetrap uses a weight activated latch and a springy support to dump the mouse into the bucket, and then spring back into the latched position ready for the next mouse. Just bait with a little peanut butter at the end of the plank. Get files to 3D print your own at: thingiverse.com/thing:4850657
Note, to keep the mice from jumping back out, put shredded paper or something soft in the bottom of the bucket so they've got nothing firm to push off of.Roller Squeegee / Roller Towel for Court DryingJeff Kerr2020-11-16 | This is a demo of using a roller squeegee and roller towel system to quickly dry off a tennis, pickleball, or basketball court.

It is a 2-stage reducer, each stage driven by the same eccentric hub, which eliminates the complex set of output pins found on conventional cycloidal drives. It also has an integral slew bearing so that large overhang loads can be mounted directly to the output plate.

This is really just a variant of a compound planetary gear head, where the flexing ring takes out most of the backlash. A 3D printed flexing structure couples the flexible gear to the rigid output ring. The overall reduction ration is 155:1.

Unlike the standard HOG Drive with a full pitch/yaw gimbal, this uses a rotating sleeve to hold the motor/wheel at a fixed angle from vertical. With a fixed angle, only a small slice of the hemispherical wheel is needed, i.e., a Partial-HOG Drive, or PHOG Drive. (Note the steering belt and motor are not shown in this animation.)3D Printed Gyroscopic Exercise BallJeff Kerr2018-01-28 | This is a 3D printed version of the Dyna Bee exercise ball.
