DISQUS

Don't worry! I know how you feel. There's plenty of instructions for easier robots that don't use such small parts. Some are battery powered, but can later be modified for solar operation. Here's a couple of my favorites:

These can give you a great deal of practice. Plus, they won't cost nearly as much.

If you need more help, you can email me, and I'll give you some more links. Please note the it'll take me a while to reply (week or two). I don't check that email account much, but I will respond eventually.
