3D model 43 – 3D štampano

This is my fourth iteration of the fiendishly clever walking toy invented by my friend John Jameson back in 1981. It mechanically gears a spinning gyroscope (made of 104 pennies!) to a cam which pushes a pair of feet up and down. When one foot goes down, the body actually lifts up and then starts to precess clockwise. Then when the other foot comes down, the body lifts again, but this time precesses counterclockwise – and voila, it walks!Unlike my previous versions that used o-ring belt drive reductions, this version uses printed gears that are more efficient, run for longer, and are easier to assemble. The parts list and assembly instructions are below the video:Parts List3D printed parts:2 sides, 1 flywheel, 1 retaining ring, 1 cluster gear, 1 collar, 1 eccentric, 1 link, 4 bars, 2 legs,
