Re: Stopping a Triple Balance

Quote:
UNLESS your mecanum-drive robot has (1) "super-creep" (low geared, high torque - I think that's what they call it, I'm not a mechanical type) mode where it just crawls right up there, alone OR pushing another bot, and (2) "e-brake" gyro-based software which enables it to hold its position on the bridge using micro-adjustments (that's in lay terms and I might not be getting it right, but it's the general idea).
I dont believe torque is the problem with mecanum wheels. The problem is that mecanum wheels just arnt designed to go up a ramp. I believe that when going up, the rollers on mecanum wheels (those that are the whole reason the function to strafe) just act like casters and you slide down the bridge. This is what we saw in very early testing anyway. In a way, this can be looked at as having "very low traction" on the bridge.

Anyone else see the same thing?
