Lupe-PM-1 hour-Open Lab:Slow Progress

So today I tried to fix the droop of the arm, and the loose grip of the claw. I was testing to see if it was a mechanical problem, so I tightened all the bolts that might seem a bit loose. That didn't help in the slightest, I even looked at the gears to see if they were misplaced or something, but everything seems alright. I am assuming that it is a electrical thing, so I will be testing the motors and looking at the wiring the next time we work on it. I will also see about new designs for the claw to see which one has a better grip and more efficient.
