I'd love to see someone scale this drive system up to FRC size. The popularity of swerve drive, and other omnidirectional drives, isn't going away anytime soon. It seems that a major technical hurdle facing teams is building the wheel units and linking them all together... and having multiple transmissions.
The maneuverability looks promising.
