The key difference between a human on roller skates and a robot on actuated wheels is that the robot, if it’s engineered properly, can exert control over its wheels with a nuance that we’ll never be able to match. We’ve seen this in action with Boston Dynamics’ Handle, Handle, although so far, Handle hasn’t seemed to take full advantage of the fact that it’s got legs, too. To understand why wheels and legs together are such a game-changer for robotic mobility, we can take a look at ANYmal, which seamlessly blends four legs and four wheels together with every movement it makes.

I'm gonna need to update Blinky. Those propellers could be wheels.
