The more important issue in my mind is how the shock is applied. If the robot sustains a shock to the chassis, that shock is going to be applied pretty much uniformly to the transmission, assuming it's mounted solidly, shaft supported, etc. As I understand it, the failure that's being seen is a torsion problem. It's specifically failing at the joint where the shaft is attached to the planet gear carrier plate. Very much apples and oranges in making any comparisons.
