I'm curious, in the final design, will you be using only two CIMs for your drivetrain? Will the other two be used (needed?) for the arm? Looking at the picture (the angle makes it a little difficult to tell), it looks like only the front (I guess?) wheels are powered, are you leaving the omni wheels unpowered? If so, why?

we are using four cims for drive and using the toughboxes all four wheels are chained. The arm will be using 2 window motors linked together to allow the arm to stay in place and 2 pneumatic cylinders for arm extension and control

That sounds great, then, and clears up the only confusion that I saw. Thanks!

CG looks a lot higher than I would like.

its nice to be able to compare... Right now our teams seem to be in similar stages. Solid design. Is everything hand welded and cut?

Yes. All cut and welded in a fellow mentors garage. The tower is actually made from a thin grade stainless steel. Ended up being lighter and stronger than a thicker grade aluminum.
