The Gearless Gearbox

What if the 2 falcons were powered pulleys and the wheel was one big one? The belt would just wrap around all of it… reminds me of that bot in 2016

(i tried to do a 4K rendering. it’s uglier than i expected given that i uploaded a decal on the wheel. Since i uploaded it to Microsoft Whiteboard the quality may have diminished as well.

So 135 actually ran something like this back in 1998. The picture is obviously a retrofit to the original design using more modern motors (I think the original design ran drill motors). I am told this method actually worked fairly well back then. The build in “clutch” of the system made sure the motors did not burn out.

I got the opportunity to drive this robot a little. It was very fun to drive, but struggled with precise movement. It certainly wasn’t going to win any pushing matches.

Certainly not advocating for this method in modern FRC.

You should mount 1 of these to each side of a rectangular frame milled from a solid block of 7071 aluminium on your sponsor’s 5-axis mill.

8/10. Wheels are not decagons.

The rubber friction drive has high losses because the energy used to compress the rubber never gets returned to the system. Drives like this that use very hard steels pressed together with high contact pressures do exist. The NuVinci bicycle hub is one. Napier in England used a similar scheme to connect a diesel engine to an exhaust power recovery turbine and a supercharger in an early attempt to develop a turboprop that had good fuel efficiency. The NuVinci hub uses special oil that is slippery at low pressure and sticky at high pressure.

Yes, the Napier Nomad.

Now I want to see a chain-driven version.

At this point why even have a wheel? Just use the falcon body with slip rings!

If you use a Neo, you wouldn’t even need slip rings just tread. Free speed of around 60 ft/s; better use decahedral tread.
