Hello. I am a middle schooler who is interested in building moving robots. The projects that interested me the most are those about building quadrocopters or solar boats or cars. What would be a good project that is cheap-ish? I will be paying for most of the stuff, and I have a very limited budget.
I have very little experience with electronics, but my dad is very accomplished and will help me if I need help understanding something. Also, my neighbor is retired and makes large amount of electric projects, like airplanes.
Thank you for any information or suggestions.
