The traction wheels are each paired with an omni-wheel that is packaged into a module. The Omni wheel axle acts as the axis for selecting between traction or Omni (Omni wheel is fixed, traction wheel travels up and down). The pneumatic cylinders are extended to apply force between the traction wheels and the carpet when additional traction is needed. The center Strafe wheel is also on an actuator to either extend or retract. The strafe wheel is retracted while traction is applied and extended when traction is retracted.
