I "upgraded" to OpenCat 2.0 and have noticed some problems. Tail servo is now designated c3 instead of c2. Is this intentional? I notice in preprogrammed movements, the tail does not move as it did with the older code. I can successfully make the robot crawl/walk/trot forward, left, and right, but pressing the "backwards" button on the remote makes it walk in place. Is there a way to check/fix the keymapping?
