A much improved Rhino. First of all, he is now an Indian Rhino, with the heavy armor skin folds on both sides. Secondly the head has been completely revised. Moving the IR sensor lets him have the proper little piggy eyes and big ears. Third the leg action is completely different. The legs are locked and braced, strengthened so he can gallop when he charges. The complex leg mechanism has been replaced by a much simpler one. Inside, the leg position sensor of DynoR3X is still being used, but the program has been entirely rewritten for more optimal leg position in turning and galloping. The LDD file is always miserable with angled beams but it should give you the idea. Just make the obvious connections and angles. I would be delighted if somebody uses the LDD and ev3 files to make their own rhino and reports on it.
