Parts Scavanging

A project log for The Robot with Balls Experiment

A new kind of gearbox. Holonomic transmission, direct-drive and continuously-variable. From reverse to full-forward, and in any direction.

Electric motors are from an old rusty rack full of cassette-player mechanics. Motor model is SANKO, 6V, CCW, stabilized RPM. Google doesn't know much about the motor datasheet, must calculate the RPM, or at least measure it.

.

The balls are about the size of a ping-pong ball, but made out of 1-2 mm thick plastic instead of the brittle celluloid. They were initially scavenged from a roll-on bottle, in order to be used on a some 2 wheels platform as a replacement for a 3'rd caster wheel.

It is a grand adventure when using used / salvaged parts and materials. Your gearbox sounds very much out of the box and looking forward to seeing how it turns out :-)

Yep, salvaged parts are not exactly the best fit. Just realized that the motors are too fast. Will see how to overcome that. Thank you for following the project.
