Done properly, under 40 lbs.

Where did you find out how much 461's prototype weigh? Or any mecanum - traction combo, anyway?

I heard (if you're wondering where, in the pits at Atlanta) the 148-217 drivetrain this year, while it had an extra wheel, weighed a lot more than that.

For Overdrive we had a robot with eight wheels that could switch between two sets of four. The chassis sitting in our shop weighs under 40 lbs, though barely.

I'm not sure what you're referring to, but when my team quotes drivetrain weight we talk EVERYTHING; wheels, electronics board, battery mount, chain, bolts, etc...

If you hit 40lbs with that standard, I'm highly impressed.

It's about 40 lbs with all the wheels, the old IFI control system, battery MOUNT but no battery, and all the pneumatics.

Reminds me of team 980 in 2003, but they did it for switching "gears" not directions.

Very cool idea. I like the innovation.

As is, how much does that weigh? (not how much will it weigh eventually...)

something i thought up that could either be more complex or simpler, a tank drive, with only omni wheels and some method to prevent sideways slip, that turned into a holonomic drive by angling the wheels. i think that because there would only be one set of wheels, it might leave more interior room for electronics and what have you.
