4M Green Science Solar Robot Kit - Green Energy Robotics, Eco-Engineering - STEM Toys Educational Gift for Kids & Teens, Girls & Boys (Packaging May Vary), Multi

Wow this works perfectly. It was my first solar power toy. Very easy to fix

Overall, kids think this rover is cool and it does teach them about solar energy in a fun manner. That said, the kids (grade 5) put this together themselves and were outside on a super sunny day and the rover did NOTHING! When we came out to inspect it, it turned out that the black and red wiring was not making any contact to the electrodes underneath the solar panel itself. We popped the panel out of the housing and saw that the + and - were flipped to the top of the rover when they should have been at the bottom. We popped it back in the right way, inserted the wires so they touched the electrodes of the solar panel and the rovers motor started spinning immediately. For those of you who also have the same problem, double check that the wiring is making contact with the correct part of the solar panel. :) Enjoy!

Decent value for money and he learned alot from it. He is 10 and used it for the science fair. No missing parts and worked.

The 4M Solar Rover Kit teaches children how to harness the light of the sun to power everyday objects. Transform a recycled soda can into a solar-powered rover. This kit includes all the parts necessary to build one solar-powered car.

My 9yo built this gift alone and had fun watching it over up and walk (slowly). His shadow was enough to stop it immediately, which he had a lot of fun with.

Needs an extra part

The screws were a little hard to get in but the directions were easy to follow and it was so cool to see it work!!

My son and I had fun putting this together. It works and helped him do something new
