Yes, the title explains it pretty well. In this Instructable I will show you step by step how to construct a light sensitive, solar powered, robot. All you need is some parts that can easily be found in the trash or in your backyard. I built mine totally from trash.
Step 1: Bits and Pieces
2- 1.5 volt motors
1- AAA battery pack that holds 2 batteries
1- On/Off switch
1- Old solar powered garden light
Random bits of wire
And something to use as the chassis for your robot, I used some bits of Erector Set parts, but almost anything can be used.
Needle nose pliers
Scissors or wire cutters
A vice grip (optional)
Magnifying glass (optional)
Soldering iron and solder (not optional)
Glue gun and glue
