The first original or the reboot?

Is that thems awesome arms and stuff

It looks like it'd be able to climb stairs, though very slowly, with a different program. The step program involves driving to reposition the body above a step, but with stairs it would need to move it's body without driving forward to do so. The only potential issue would be the legs interfering with the steps, though a resign to incorporate arched legs would probably fix this. Alternatively, using a walking gait of standing on opposite corners may work, where front left and back right wheels are planted while the front right and back left wheels are repositioned to step up stairs, this same gait would also be useful for a single step and would be much faster; the fact that each leg can pivot makes this gait much more possible, especially in initial and final steps, as the robot can have three points of contact while one leg is lifted onto or off of the initial or final step. Though, this is ultimately reliant on how heavy and dynamic the full robot is, not just the driven platform, as weight shifting can entirely null this solution; but at the same time, a hexapod or octopod variant of this wouldn't have such severe limitations, or the implementation of a mid-leg 'knee' joint may alleviate some of the unforeseeable balancing issues depending on overall flexibility of the leg and range of wheel positions.
