Re: Mecanum Holonomic Drive Setup
The only holonomic drive I know of uses 3 or 4 fixed position omni wheels (rollers at 90 degrees to wheel direction) equally spaced around the robot, (120 or 90 degrees apart). The wheels themselves don't articulate, and each is identical.
Mechanum drive uses 4 wheels in a standard 4wd setup, where each wheel has rollers at 45 degrees to the wheel direction. Opposite corner wheels are matched for roller polarity, so two each left handed and right handed wheels are needed. The wheels dont articulate.
Swerve and crab drives physically rotate the wheels to point in different directions, but the wheels are normal and don't have rollers.
