In fact, we currently have a surgical tubing counterweight pulling it down


This might be another contributer to why this isn't working.

Like I said, unless we can design a brand new type grabber in the next three days, I think its going to stay that way. Any suggestions for quick, simple, light grabbers? Keep in mind that we would like to keep floor pickup.

EDIT: We are measuring current with a clamp on multimeter. I can't do anything to the robot right now because it's in the school machine shop, and im in my house.

DOUBLE EDIT: We already have delron sliders at most contact points, and nylon washers at some others.

since you only have the RS 550 to work with... Is it possible you can press the pinion gear from a fisher price motor and drop the RS 550 into the Fisher price gearbox? The added power should be enough.
