The Tri-drive mechanism

This mechanism in:
  1. horizontal orientation can be use as the tri-star wheel set. Rolling mode is used on a flat surface, acting as any normal wheeled vehicle.
    Climbing mode is useful, when encounters enough resistance to start climbing.
  2. vertical orientation can be use as base for whirligig toy, rotating around own axis.
This set has a concentric drive arrangement to provide separate power for both rolling and stepping modes of operation. In this set Technic Beam 1 x 5 Thin with Axle Holes on Ends is used. However manipulating with length of this Beam | Liftarm you can adjust the length of the arm.
