Also have you guys put your arm through some serious testing?
I noticed that you raise your arm outside of your safe zone, could you arm and bot take a really hard side hit in that zone?
I also see a lot of swaying back and forth when you are moving in that zone. A robot that only plays defense may torque that arm way out of line, perhaps making the arm a little stronger, or bringing a good supply of spares may be an option (so long as they are light).
And one more point, when you were driving and making some sharp turns your claw seemed to also sway side to side, making a nice "cradle" where your arm could rest in could easilly solve this problem.
We have played with the arm lengths and wrist lengths so that we can raise and lower the arm with ease while completly in the safe zone, to make sure we stay functional.
Just a thought, but looks pretty good so far.

Thanks for the input.
The lower link has been replaced with an aluminum unit, which has made the arm substantially more rigid as it travels up and down. The swaying left to right has been taken care of by adding more support to tie the top of the arm super structure in with the base. We've also added a guide of sorts that the arm falls into while in the down position which limits the sway of the claw to approximately a half inch.
As far as the arm being raised outside of the safe zone, it's not really something we're worried about - yet. When at it's lowest point and at the top scoring point the arm is contained completely within the frame and bumper perimeter - and the arm can be raised from it's lowest point to it's highest point while remaining completely in the safe zone. More often than not, if we're approaching the scoring grid unobstructed then we will raise our arm a bit early, but if someone is waiting to play defense on us then we will wait until we're in the safe zone to raise it.
