I have dreamed of some sort of power-articulated suspension for an electric crawler. Basically, you would be able to individually move each axle with at two degrees of freedom, and at the end of it, there'd be a super high torque electric motor and your tire. You could add another degree of freedom at the hub so you could do crazy s*** like pick your tire up and place it tread against a wall or something - you could place the tire anywhere, at any angle, within some radius of the body/frame. In the event that the electric hubs weren't powerful enough, you could "walk" the truck by moving the linkages to the hub.
So, hell yes, I'd love one of these. But bigger. And better. And not as comfortable. And way, way more dangerous.
