Dentists recommend brushing your teeth for two minutes twice per day. Well, good luck explaining that to your little ones! Tooth brushing is boring, we totally get it; but what if a smart Robo brush could help kids to make this routine more fun? Let’s try it out!
Time: 10 minutes
You will need:
- Main Block
- 1x DC Motor
- Connector Block
- Button
- 2x Universal Connectors
- A toothbrush
- A rubber band
- Some Lego® Technic pieces (optional)

Step 1: Build the base for your toothbrush by attaching the Main Block, the DC Motor, the Connector Block and the Button together.

Step 2: Place the toothbrush in the middle of the rotating part of the DC Motor and secure it with the rubber band. You can place some Lego® Technic pieces on top of the rotating part for more stability.

Step 3: Time to program your device! First, create a loop out of two Motor actions, adjust the speed and the distance.

Step 4: Drag a Wait action onto the dashboard, connect it to the Motor and add a Button condition to it. Program it to “Pressed”.


Step 5: Create a loop and add one more Button, this time set it on “Released”.

Experiment with different combinations and add more Button conditions! Here’s what we suggest:

That’s it, works like a charm! Beware, your daily toothbrushing routine might be taking longer than 2 minutes from now on. It’s just so much fun! 😉
