Window Motor question

[Grim Tuesday]

Though we have lubricated everything already, the surgical tubing counterweight is a good idea. We already considered making our spindles smaller, but we have no easy way to do so, considering how they were made.

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.
