Here’s a basic list of nearly all the parts/components in/on the finished robot. I bought most of this from Sparkfun, Jameco, or RadioShack so I’ll reference my links to their specific products, although most of these parts could be purchased elsewhere and probably for cheaper. Some of this stuff I didn’t buy (already had most of the equipment), but I’m also including a link in case someone wants to buy one. I’ll try to include pretty much everything I used in the process of making this robot. Pretty long list. Controller: 1.
