A Hopper Race!


Build your hopper.


You'll start here.
You’ll test this one and then modify it to (hopefully) create the fastest hopper!

Alright, test your hopper!

SPIKE Invention-Squad Hopper-Race Step03-Program - en-gb

Play the program and watch your hopper move!

Build prototypes of new legs


Come up with at least 2 new ideas to make your hopper move even faster.

Remember: Anything’s possible, but you can’t use wheels!

Here’s some inspiration, but can you think of a better idea?


Test Your Prototype


Place 4 bricks of 2 different colours about d=50 cm apart to create a start line and a finish line.

Place your hopper at the start line and play the program. 

You might have to adjust the programming block values so that your hopper covers the distance.

On your mark, get set, go!


Which team built the fastest legs? 

Explain the mechanics of your prototype.

Did you use gears, levers or pulleys?

Make the race more challenging by adding some loose bricks to the test track. Can your hopper walk over them and still get to the finish line?

How did you do? 


What did you do well? Is there anything that you could’ve done better?

Being an inventor also means improving things. Well done!
