  • My Blocks

The challenge

How can you program a robot to repeat a sequence of moves?


A dance robot that uses nested loops?

2. Try it for yourself

Once you’ve watched the tutorial, have a go at creating some of your own My Blocks as well as some simple dance moves that use a Loop.

Note that you can set a Loop to either repeat forever, stop after a number of times (count) or for an amount of time.

Feel free to experiment with the Move block duration settings.

3. Share it!

Finally, take a screenshot of your dance routine and add it to your team journal (use the Add Media button at the top of the screen when you’re editing your post).


Next: The great dance off!
