I don't sell Cricket Robots, Cricket Robot parts, or documentation. Everything you need is on this site. If it looks too difficult, try one of the great walking robot kits from http://www.robotstore.com or http://www.lynxmotion.com
I will continue to improve and update this site which has enough information for you to build your own Cricket robot. Download the parts list and manual to get an idea of what you'll need. Cricket parts are made from readily available materials. Good luck with your robot project.
