I wish first would let the robot weight be 131 pounds
Ohh well we came in at 131 fully loaded and we were actually able to shave off 4lbs off the electrical system if you can believe it. The terminal strip and a huge amount of 10 ga. wire is now on the floor and we have more weight now for armor. By far the biggest weight cam from gears, we were able to reduce most of the larger 20 pitch gears by 70 % by turning down hubs and drilling holes, and in steel terms thats alot of weight sometimes over a 1lb at a time. Also look into the fastners on the robot, we found BOSCH gussets in places they were not needed and extra t-nuts where they weren't needed. Heck we welded a bunch of parts to make them lighter also.
