Those look like Colson 4x2" wheels on the swerve modules? How well do Colson wheels perform on tile/concrete/asphalt/grass/gym floor?

Swerve on asphalt or grass is a little iffy to me. On a gym floor however these will preform fine and colsons are probably the best option for durability.

Yeah, I'd say the wheels the OP chose are by far the best for the situation, but it's something to consider. Can the swerve capabilities be disabled for driving on certain terrains?

That would effectively turn it into a standard 4 wheel tank drive, which might actually be worse for turning due to the scrub it would induce than just staying with swerve enabled.

There are other possibilities - you could do an automotive or fire truck style steering setup, for example.

Depends a lot on wheelbase considerations... Looks like it's a square, or nearly so, so turning shouldn't be as bad as if it was a long-base. And there's always the possibility of a "spin-in-place" mode that would allow for quick turns.

Regarding the corners...

I see you're using one big beefy 1/4" gusset (which is the swerve plate as well). I'm a little leary and would consider running another crossbracing underneath in the corners, to take torsion in the siderails better.. Unless you already have that? Hard to tell.
