+ | * The 4 in wheels are helpless (without tracks) once the robot is onto the mid & high sections of the mountain. Except, the 4 in wheels can help prevent roll-down. | ||
+ | * Treads (tetrix treads) do not drive well in the floor. | ||
+ | * With a 50 deg angle in the high section, traction and center-of-mass are of first concern. | ||
+ | * Articulated forward tread extension facilitates climbing. It also allows center of mass to be shifted forward and down as the robot climbs, improving stability and traction. | ||
