Three shaft Nano Tubes are intended to be used as a complete drive module for the side of a 6-wheel-drive robot. The center shaft is slightly lower than the two outer shafts for better turning. These Nano Tubes have one of the end shafts powered via one motor while the center and remaining end shaft are both powered by the second motor.
Three Shaft Two Motor Fully Geared:
A fully geared Nano Tube while having the benefits of a drop-center shaft six-wheel-drive also shares the load amungs all three output shafts between both of the two motors.
