Re: pic: 1817 Teaser #2

Our clearance geometry on our 6 wheel chassis is fine. One of our engineers/college kids figured that out in inventor. My question is about traction up the diamond plate and the carpet. We are using the SBR version of Roughtop from McMaster and the two questions we have are: Will this tread provide enough grip on the diamond plate ramp to get a 130lb robot up a 30 degree incline. Does this tread provide too much traction on the carpet that the robot's wheels will jump when turning.

In my years with the Robonauts we didn't use a 6 wheel base or this type of traction tread. My initial assumption is that the by lowering the center wheels 1/8" that will help with the turning and since the wheels are 1" wide they shouldn't skip. I also think that the rubber grip that the SBR Roughtop gives should provide enough traction to climb the ramp. It is not as grippy as natural rubber, but with 130 lbs of weight on them we should have not much trouble climbing, esp with the help of 6 wheels.
