Re: Team Tuttle Park Rover
If the motor fails by seizing then I can see that.
if the motor fails because of an open coil then it would be best to have 4 wheels powered by separate motors.
If say the front right fails, you can shut down the front left and just use the 2 rear motors to travel.
It does give you some form of redundancy, but at the cost of a greater likelihood of failure (4 motors).
A decision like this would likely be influenced by our estimated MTBF under full lunar conditions.
If the estimated MTBF is high then our greater concern will be getting stuck
