It looks like you guys are leaving the realm of robot mechanics limiting your speed and are now only held back by the skill of your driver. Scary!
As usual, very slick and beautiful machine work. Any estimate on how many pounds of aluminum chips you made this year?
Looks from the pictures like your gripper rollers are powered from transmissions near the arm's hinge point... I'd love to see more detailed shots of the mechanism if you happen to have any. I can't get enough Cheesy Poof pictures!
Question for you and other roller claw teams out there... I've noticed a trend of pneumatic releases for roller claws among some of the 'elite' teams. Was there a design limitation with a straight roller claw approach that necessitated this feature? We didn't go with the roller route for our gripper mechanism and I'm curious.
