myDINOR3X is simply an upgraded version of the official bonus model EV3GAME. It walks a lot better due to a tweaked walking mechanism, as seen in the 2nd sub-picture. The mouth features more teeth, re-arranged teeth, and the (use-to-be) stick-up horn is now a top-of-the-mouth decoration. The top swords have been re-arranged and positioned, although it is hard to tell without a close look. A color sensor has been added to the tail. Many of the panels have been re-positioned. Fangs are present on its mouth. I also made another program-with the EV3 Brick Program app-that makes myDINOR3X leap and jump forward. Enjoy! THIS IS MADE WITH ONLY ONE 31313 EV3 SET.
