Monowheel/Bi-wheel
Added 2023-12-04 13:55:29 +0000 UTCHere's next week's video, early for Patrons, this one goes out publicly on Tues 12th. This is a combination of the Pedrail project and a 'monowheel', but the idea was that it's mechanically stable by itself, and a fun thing to drive. A few weird things happen though...
There's only one video after this before the end of the year which is the Makers' Secret Santa, but as usual that may be finished at the last minute ;-)

It could probably have some form of dynamic stability to make it drive more smoothly, but I didn't want to fix it that way. I guess leaning angle could be derived from a combination of forward velocity and the differential drive.

2023-12-05 10:33:22 +0000 UTCThat would probably help a bit, but I think the main problem is all the legs getting stick and the friction caused as they move in and out / getting closer and further apart. I'd like to make a big one I can stand in, but it might be a crushing hazard ;-)

2023-12-05 10:31:57 +0000 UTCI'm sure there's a physics explanation for the weird little dance when it turns in place. I wonder if you the leaning can be more programmatically subtle to account for turning at speed rather than simple jaunts around the kitchen; though I imagine it's only useful at significant speeds. Otherwise, like you discovered, it loses traction pretty fast. Cool ideas being implemented, as always.

2023-12-05 03:52:10 +0000 UTCI wonder if you had more of the mass lower and centralized, or even more (larger batteries), would help prevent the center section from over-rotating? Love it! Such a unique combination of ideas. This would make for such a crazy ride when scaled up!
