Re: pic: Two bot side balance
It is just a a simple CG trick. 98 lbs on the right side wheels, 20 on the left. We sit on the rail, with a simple guide that its twice the width of the flange for alignment only. The belt drive gives us traction on the top surface only.

This was a huge design commitment for the team. All 4 Cims and gearboxes are on the right side with a driveshaft to the left wheels. The belt is driven by this shaft, geared for the same linear speed as the wheels. We have 30lbs of balast weight on the right side C rail. And a sliding battery tray. The super low CG also makes us a good stable two bot regular balancer too.

Thanks to all for the interest. We were honored to receive the Creativity Award at Livonia districts.
