You could, and you could also make it just as fast.  Increasing the speed in the drilled approach or in the gripper approach ultimately comes down to how much power you can throw at the problem (the energy required to accelerate and then decelerate the moving parts would be the limiting factor).<p>Its fun to imagine a situation where the level of power had been taken to such an extreme that even a slight hitch of the cube&#x27;s parts would result in an explosion of tiny bits of plastic showering the room :)
