Re: pic: 4143 differential swerve concept

Increasing the spacing between the wheels should improve steering stability. Perhaps if they were outboard of the gearboxes things would improve enough to become usable. With a bit more adjustment, this could also be used to lower the CoG of the module even farther, though with an increase in MoI around the serve axis and a need for more real estate for the module.

If I understand correctly, that would be crab drive, not swerve. Crab allows you to translate anywhere, but not rotate the robot effectively.
