Speedster Aliens

About the Car

Our main goal was to design and build a solar sprint car they could go super fast using as many green energy components as possible. For that reason, we named our car Speedster Aliens. Some of the obstacles we encountered were we had a little complication because a part of our wood chipped off. Also, our gears were touching and we needed to cut out a bigger space in our wood panel. Something special about our car is we used Tinkercad to make 3D printed wheels.

Our solar power test was faster than our battery test, especially when there was more sunlight. An idea to help improve of solar sprint car’s performance would include reconnecting the clip to the wire.
