Ike,
I was trying to visualize the forces transferred to that part during a collision. (I am trained for failure analyzing) If both robots are traveling towards each other then for an instant we can believe the motors can be considered to be in locked rotor mode. That transfers all of the potential energy of both of the two robots to the drive train of each. It is in that moment of collision (with another robot or the wall) that would then transfer the maximum energy to the part in question. Still your 1080 number is pretty impressive when considering the forces involved.
