4M 3782 Green Science Solar Rover Kit DIY Solar Power, Eco-Engineering Stem Toys Educational Gift for Kids & Teens, Boys & Girls

In general, kids think this rover is cool and it teaches them about solar energy in a fun way. However, the students (grade 5) made this themselves and had the Rover outside on a super sunny day and it did not do a thing! We came out to inspect it and found that the black and red wiring was not making any contact with the electrodes underneath the solar panel. As we took the panel out of the housing, we found that the + and - voltages were off A red light and a red laser were placed on top of the rover when they were supposed to be on As soon as the rovers motor started spinning after we reinserted the motor the right way and inserted wires that touched the solar panel's electrodes, we knew we were in the right place. Double check that the solar panel's wiring makes contact with the correct part of the panel if you are experiencing the same problem. Happy listening -).

You might find this to be an excellent option if you're just starting out The instructions were easy to follow, it took 20 minutes to build, and it worked right away for a messy project There was a bright day today. Children got impressed and are more interested in solar technology (which was intended. During assembly, be sure to have a small Phillips head screwdriver at hand. were 5 small screws in total that we used (there were 6 but we didn't use them all). Moreover, the wheels are a little difficult to put on and may benefit from some cement to keep them in place. For those who don't want to use an aluminum can, a plastic body is included in the kit as well. That was something I had no idea about when I ordered I thought it was a nice touch.

As a Christmas present, this book was given to me. While it was fun to assemble, I was dismayed to find out that our solar panels did not work, despite reading reviews which described them as working. Imagine six months in the future- I am pleased with this. At Christmastime in Utah, I think the light was too dim to make these A couple days after Christmas, we put it away after we had only used it a few times. Is it possible that there were too many clouds? It's impossible for me to recall it. Unless there is plenty of sunlight, it does not work.

Worked twice and didn't work again. I have even tried inside with my flashlight and a strong blinder since it is not much sun out Does not move at all. For solar powered toys you can buy at $1 Tree, you can also use that flashlight. We are experiencing problems with our wheels staying It was not possible to screw in any other screw but the one that screws in the can, so we taped several things. A great deal and fast shipping from this seller. I used this for my son's Science Fair Project.

It is not the first time this has happened to me. The solar panel could not be connected to it, thus it could not be used. Despite our best efforts, we were unable to juryrig it. This product was a total waste because the manufacturer didn't give us a refund. However, it did end up giving us a full refund from Amazon so thanks to them. The next time I try, it should work.

I found this to be okay. It was my son who discovered that the can don't have to be used. If you do not want it to run with, then you can turn it off. When it would move over a cloud it would stop moving. Therefore, direct sun light is needed.

The twins, that are 12 years old, had a science project to do for school and chose this experiment to do. The project was simple to put together, but it failed to work. Our home is in Alaska, so we have very little daylight, but it never worked when the sun was out and bright. In other reviews, we were directed to use LED flashlights. Despite every effort, there was no movement. Since this was such a poor project, my boys had no choice but to choose another. There is a small chance that this will work. There is no reason not to take the risk when it is cheap enough. The only thing that saddens me is that my boys never saw it in action.

Drives at a leisurely pace and has to be in direct sunlight to work. My kid was very interested in learning about solar energy through this activity. I built the kit with an 8 year old and she was able to do just over half of it by herself. Lisa Frank stickers were layered over the top of her dress Absolutely! You can create whatever you want for it. Among the only parts that were frustrating to us was that it said to cover the can with the plastic and put on the lid It reads that way to us, at least. Each of the two must be attached one at a time.
