This is the Gonk Droid from set 75253 Boost Droid Commander: Gonk Droid

The accessories for the third mission "defending the Falcon" have been added.

The right arm can punch and shoot a "laser beam".

However the left arm can only move the saw blade up and down.

I would like for the blade to spin AND the arm to move up or down. Is this feasible?

    That saw blade only has a hole for a pin, that makes it hard to transfer a rotating motion to it. Sep 24, 2019 at 10:25

    I think blade rotation can be achieved with some friction based solution: 1) a rubber wheel spinning a blade; 2) using a friction pin for a blade. The main challenge here is to transfer rotating motion to the blade. However it isn't clear if there is enough place to store the motors and connection ports for the motors.

  • @Alex, there's an internal motor from the boost move hub. It's not the intention to add an additional motor. It's indeed the intention to rotate the saw by friction. Sep 24, 2019 at 11:53
  • @MichaelVerschaeve Do you want him to move around with a spinning saw blade, or have it spinning when his arm goes down?

    If you are ready to commit such blasphemy, then gluing a small weight on the edge of the blade would result in the blade swinging or even making complete turns when the arm is moved up and down, depending on the acceleration of the arm movement.
