Combs or fingers are another method of lifting a vehicle under its tires so it can be moved within the automated parking system. A vehicle is parked on a flat surface containing combs located in the floor of the parking module. Typically when the vehicle is ready to be parked, a section of the parking module floor is lowered to allow a robot with combs to drive underneath the vehicle. Combs on the robot are then raised through the gaps of the floor combs, to lift the vehicle, before the robot returns to the parking mechanism with the vehicle. Considerations for comb transfer in automated parking include:
- High speed and reliability of vehicle pick up
- Comb car stand height and cost
- Mechanical contact with tires
