Re: H-wheel Question

It really depends on the weight of your robot, including whatever you're carrying. If your robot weighs 120lb before battery and you've got a tall stack of totes and a battery, you may very well weigh 150lb. In this case, the 20# corresponds to only about 13% of the robot weight. If you've got wheel alignment problems or other friction in your system, this may not be enough to get moving. The more force you put on those springs, the more acceleration you can get in strafing, at a commensurate loss in your tank drive.

If you are more likely to slip when carrying a load than when empty, this is quite probably your problem.
