*Note: The motor clip was remixed from someone else's design that just had a hole to screw it in; I added the base so it could be glued and made it slightly smaller to fit my motors more tightly. I cannot find the original! If you think you know whose it was remixed from please let me know and I will give credit!*

This was created for summer camp engineering challenge for 5th-7th graders. The camp was space themed so this activity was to design a 'rover' which would then be tested on different surfaces and with different loads. The day was engineering themed so they got a lesson in the engineering process to introduce the day.

Then we discussed how circuits worked (which they had good background of) and practiced with Snap Circuits then were given the challenge to create their own rover using any of the given parts (within limits of a maximum amount of each printed part). I purchased motors and battery packs with lead wires attached so all they had to do was twist wires toge
