It's next to impossible to make any judgements about tractive effort by looking at a picture. Big tires doesn't equate to big traction. Cool belts don't equate to big traction, either.

In fact, this season, I expect many people are going to have to relearn all they though they learned about traction - especially where the HDPE is concerned.

As someone already mentioned, the 300 lbf. figure you have is probably for tension, not shear. Suction cups don't really resist shear all that well, and there are robots out there that can exert well in excess of 300 lbf., anyway.

Against some robots, you'll likely be fine. . . .well, assuming that your drivetrain has the oomph to move other robots with similar ideas out of the way. Against others, you won't stand a chance. There's always someone who does it better, or differently, or some way you never even considered.

It's a bad idea to assume you're immovable, or unbeatable, or that much more clever than the rest of us.

Edit: Grammar. Also, do you understand the difference between pushing something that weighs 300 lbs. along a surface and exerting 300 lbf.?
