While your test was good as far as it went, you really need to consider the dynamic loading your robot will face.

These loads can be at least twice as high as the stall loads of the motor and are probably closer 3 times the stall torque than 2 times.

If this coupling is breaking under practice conditions, I am scared to death what we will see in competition conditions, were speed matters and the drivers are nervous as Mojo Jojo near the Power Puff Girls.

Perhaps Chemical X will save the day?
