Bulldozer Add-On for the :MOVE Mini v1 and v2 Kitronik

With this Bulldozer add-on for :MOVE mini for the BBC microbit, everyone’s favorite little programmable robot buggy just got much better. Robots often do more than just :MOVE from A to B, and with this add-on so can :MOVE mini.

This version of the bulldozer works with both versions of the :MOVE mini.

Previously on :MOVE mini, we; drew shapes, controlled it via bluetooth, controlled it with a second microbit, and we also coded a variety of light shows. Now, it can totally lift and carry stuff too!

This self assembly bulldozer add-on kit is made from the same materials as :MOVE mini, designed in keeping with the :MOVE mini aesthetic, and also comes with the servo required to move the bulldozer add-on up and down.

There is a very simple Servo:Lite board hack that enables the control of the third servo, you can find out how here. Once the kit is fully assembled, the bulldozer arm can be coded with the Microsoft MakeCode Editor.

Note: In order to use this accessory you must enable the third servo functionality to be able to connect the third servo to the Servo:Lite board, some soldering is required in order to do this. The header pins required for this are supplied with this kit. Also, enabling the third servo disables the onboard ZIP LEDs. If you undo the third servo hack and return the board to its original state, the onboard ZIP LEDs will be re-enabled. We have produced a short guide showing how to enable the third servo and how to revert this change, read it here.
