I think you are a perfect candidate for HUAR.

RoboGuide - Your guide to hacking all things WowWee

I am in the process of modding and hacking my Robo Reptile. Right now I have just redone the exterior. I am thinking about improving him with a few mechanical hacks. I also want to see what else I can add as robotic electronic features. He can be found on youtube at  http://www.youtube.com/watch?v=6z7lQSrFbmQ

Let me know if anyone has suggestions

wow, how did you make the skin? did you make a mold of the roboreptile and then paint it? does the new skin affect performance in any way? nice mod!

like that video....that is neat how u put that skin on roboreptile

Thanks all.
There are several methods to my mod madness. I measured all of Chompy's dimensions and then experimented with a number of things. I wanted to insure that Chompy had total uninhibited freedom of movement.. I painted the head and part of the body initially to gage the over all look. I decided that fabric would be the best choice for Chompy's skin. I found some reptile like fabric after a little hunting. Fabric provides a realistic look and also offers flexibility in movement. When I looked at real Reptiles, I noticed a lot of lizards have looser, wrinkly skin so the fabric made it look more realistic. I fabricated the eyebrows, tusks and the spiky row of spines on his tail and neck from plastic. I also wanted to be sure that all of his sensing functions continued to work. All his movement and sensing ability remain intact. I took pictures of the modding process while I was working on Chompy and I will make that into a short video. I will post that as soon as I put it together. Chompy has "star quality" and I think he aspires to play lead roles in a few more videos. I am going to work on the feet next.
