Thanks Stephen. If you click on the link it will take you to info, pricing and a startup video showing how easy it is to use. I believe I have created the best UGV going and almost 50 other inspectors (BIGCrawler clients) will agree. Two major r/c companies approached us to part of the project and are now supplying parts, Holmes Hobbies and BentMetal. Let me know if you have any questions.
