High friction wheels on carpet in turns causes high (and I mean very high) currents in CIM motors. Assume that the CIMs are going into stall every time you turn. I bet it would not be unusual for the CIMs to be running at 100 amps in turns, each. 100 amps means about 1200 watts per motor, all things being equal. Yes that is like four 1000 watt light bulbs in your robot making heat. The fix is changing the height of the center wheel, change some of the wheels to omnis or a combination of the two.

No, we have a dropped-middle wheel design
