Looks like quite a beast... I'm impressed.

Thanks, in the past we've had little luck with arms, so we're quite proud of this one. It extends to ~9 ft. The centre of gravity is not too bad, overall this robot is quite short (several inches under 4 ft), and most of the motors and the battery are mounted pretty low, plus we'll have bumpers mounted to further lower the COG and act as wheelie bars.

~115 lbs. The arm without motors is actually about 20-25 lbs, the reason it looks so much heavier is that it's made out of four pieces of aluminum angle and one square tube, and in this picture the angle has it's long side facing the camera. Thanks for the comment on its looks, but if you saw it from the other side, you'd probably think differently. 13 PWM cables from the arm/turret sensors + 4 from the camera + 1 for the pressure switch + 6 for Victors + 2 for spikes + 1 for the gyro in a tight amount of space leads to a really nasty looking electrical board. (We'll try to fix that at VCU, we don't want our insectors pulling out their hair trying to see what is going on in there)
