I see that the belts from the motors were swapped top-to-bottom and a tensioner added. Did your team find problems with the bridged belt slipping? Excellent work, by the way.

The bridged belt itself was sound, however when I was calculating the belt path in Inventor I accidentally referenced the wrong dimension and ended up with a path 4mm too short. This resulted in the serpentine belt slipping over the output pulley under high torque.
A shorter belt to fit wasn't an option but I was able to use an existing bolt to create an idler with R4a bearings. I swapped the belts to reduce the distance the idler (and the pulleys) would be cantilevered.
