How to motorize a LEGO conveyor belt with littleBits

For the Illumination challenge, my son and I used a DC motor bit to power a LEGO conveyor belt. We made a short video to show you how to do it. It’s simple to make if you know a few tricks.

You’ll save time if you first slide the motorMate onto the “D” shaft of the motor, and then, slide the cross axle.

If you don’t secure the tethered DC motor, the motor part will rotate onto itself a few times before it starts moving the conveyor belt. For these reason, we press the motor onto a littleBits mounting board. Get more mounting board tips & tricks here.

Supplies you’ll need:

  • 1 LEGO conveyor belt
  • 2 LEGO cross axles 3M
  • 1 LEGO Round Plate 2 x 2 with cross axle hole
  • 1 LEGO Round Brick 2 x 2 with cross axle hole
  • 1 LEGO bush for cross axle
  • 1 littleBits DC Motor bit
  • 1 littleBits motorMate
  • 1 littleBits mounting board

I hope this inspires you to make your own inventions. Start making!
