Really, I'm not trying to be a dickhead. However there is a ton of information out there that's really easy to find and no one here is going to research it for you. If you have a specific question (i.e. "What is the best way to detect a particular fruit" or "What kind of problems will I run into trying to waterproof my robot" or "I can't figure out this electrical schematic") most people here will be happy to try to help you, though!
