Swivel casters give the worst of all scenarios. They give no traction (for pushing or resisting being pushed), and will (guaranteed) be facing in the wrong direction and cause your robot to not drive straight when starting to move. They do allow for fairly easy rotation of the robot. Cannot be powered. Swivel casters without suspension tend to get "shopping cart syndrome".

Ball casters also provide no traction,but do not interfere with the robot going in a straight line. They allow for much easier turning of the robot (easier than swivel casters). Cannot be powered.

Omnis provide traction (if powered) in one direction but not in the perpendicular direction. They allow for fairly easy rotation. They are expensive compared to casters.

Hope this helps.
