Today I uploaded my new Lego Technic Bus.

It has a few functions:

  • Working doors (front and rear)
  • Drive
  • Steering

The bus has pneumatic pump, a pneumatic switch, a thin large pneumatic cilinder and 5 motors:

  • XL motor for drive
  • Servo Motor for steering
  • Two M motors for the doors
  • One M motor for the pneumatic pump
