Swerve with a twist

[Harshizzle]

So after a discussion with my mentor about swerve drive, we thought of a potentially new drive system that is swerve like but a bit different.

What we pictured was a swerve module where the wheel was extended out from the center of rotation.

(top view- The o represents an axle going through the computer screen).

When the wheel is powered, and the o axle is prevented from spinning (perhaps using a brake system), the robot would move in the direction the wheel is spinning.

When the wheel is powered and the o axle is allowed to freely rotate, the wheel would turn in a circle, and could end up pointing in a direction you want it to.

With both those combined, the robot could have holonomic drive capabilities.

The biggest problem I see with this is the weight distribution, as the force would be on the o axle, which would not be touching the ground (or maybe it could hmm...). I also dont see this as very practical for an FRC game, because swerve would probably be much faster at orienting itself.

But this drive system would make every swerve module require only one motor and one braking system, which in some industrial applications, could be better.

Anyway, does this already exist somewhere? If not, thoughts?
