Roller is TrackSystem.Components.TrackWheels.Base:
    .doc: """
    A roller wheel with a rigid body. A cylindrical geometry can be added to the wheel via e.g. the CylindricalShape trait.
    local_center_axis is y direction by default assuming that the non rotated cylinder axis is in y direction.
    Note that the all track wheels should have their axis in the same direction as the sprocket.

    Example:
        roller is Vehicles.TrackSystem.Components.TrackWheels.Roller
