I like it, not sure on how reliable that this may be, or how accurate, but I really like the fact that you can control the inner tube with little surface area on the object. If thought out correctly, machined, and executed I think that this may very well have a good shot at being one of the better arms out there. Very simple, low complexity design. What else would a good engineer want? Hopefully programming will not become an issue with this arm, but I do think that you did a great job not only thinking it up, but also designing it as well.... so overall... Nice Job! P.S. Looks like the crane game...
