The 10 year long affair with single paw controllers got lions wondering why the concept was never applied to skateboards & scooters.  They still require a handlebar or the operator to balance & don't have any auto steering capability.  A skateboard by now should just be a fixed platform that the operator commands to turn & move with no physical coordination.  The single paw controller has always done this well.

The key innovation is going to be a steering mechanism.  10 years ago, there were no good ideas but skid steering.  The big thing these days is the swerve drive.  They have 1 motor for traction & 1 motor for steering.

It would be unpowered & front wheels only.  The swerve drive is just tall.  A lot of the parts are just to power the wheel.  This one has the motors on the side.

This one has the motors on top, like most of them.  The rear wheels would be conventional powered skateboard wheels.  Lions are nowhere close to building one.

Because of the size of the swerve drive, it might be a triangle skateboard.  The traction wheels go in back & the steering wheels go in front with some kind of elevation.
