Re: Team 245 Gearbox

Hey hey... a lot like our design. We have our motors on the same axis as the wheels, and our wheels are hollow so the gear reduction (cim: 1:11, drill: 1:41) actually fits within the wheel. Plus it is swivel drive. But it looks very cool and seems to be a very good way to get up the stairs. Too bad we use 6" wheels, we cant do a thing about the stairs.

Re: Team 245 Gearbox

So was this a design from Hildebrandt? I know he'd always been thinking about stuff like that.

Re: Team 245 Gearbox

FYI: Little history and explanation of the harmonic drive. (Link)

Did you guys manufacture that or is it off the shelf? Either way I think it's very cool. Can't wait to get a closer look.

Re: Team 245 Gearbox

Nah, hildebrandt didnt design it.

We manufactured it ourselves. it took lots and lots of man hours... we only broke 2 CNC mills though... we made 7 of them. Our design is based on the "if we shove this piece into this piece, it will work!" method, and it works really well. It makes a cool humming noise, too!
