How about this for a thought - I remember reading somewhere about using the
differential to keep a tracked vehicle on a straight path using one rotation
sensor:

By using another differential in this capacity, it should be possible to detect
"wheelspin" type situations such as the one you described when mounting an
object at an angle and one wheel rises off the ground. Upon detecting this
situation, you automatically engaged the diff lock. When to disengage the diff
lock would be another matter entirely - perhaps a timeout would be appropriate?
