Thanks for the compliments! Everything was functional the day we shipped it. Although we are still working on the Auton code with the identical practice 'bot. There were some issues with the winch system as well and we are working out the bugs so the system will be fully operational for Great Lakes. The majority of the weight is in the chasis, the arm and turret only weigh 35lbs.
Basic systems include a goal grabber, 6 wheel drive with the center wheel articulating similar to the 2003 robot, the arm mounted to a turret with a claw deigned to handle the 2X balls. We also have the hook on the back side of the arm for hanging. Also on the chasis is the 5X ball coraller. The rear of the chasis is clearenced so that we can climb the 6 in riser, which suprisingly it does very well for 8" tires! Any other questions?
