Abstract
A method is disclosed for a robotic vehicle to climb a step. The robotic vehicle uses tracked flippers to engage the top of the step and drives with additional tracks other than the tracked flippers. The robotic vehicle also shifts and tilts a payload in order to move the CG of the payload ahead of the vehicle chassis and past the edge of the step.
