I built this 'bot using aluminum tubing, Hawker Genesis EP16 Batteries, OOPIC Control Boards, 4QD Motor Controllers, Futaba Interface and Bosch 750 motors (2ea). I also integrated an on-board 360 view camera set-up which is relayed via 2.4 GHz x-mitter to a Monochrome Heads-up display. caf-FIEND was built to compete on Season 3 of Robotica, but was disqualified at in the holding pens due to a safety violation. I made the armour surrounding the Pneumatics too thin. All that work and I failed because of 1/8" of Aluminum sheet stock! Oh well, my son loves it! You can see how I built it and alot more pics at Http://WWW.Team-FIEND.com . The design is very simple and straight-forward. I've gutted it and am now reusing the parts on the only TRUE telepresence ROBOT I've built named T.E.S.S. . I've gotten a ton of IDEAS from this particular website and am glad to be able to finally share one with you! CHRISTIAN Email: Christian@team-fiend.com
