Evolution of the Roboreptile, WowWee's Robotic Lizard Dinosaur

Here is the next installment of our 'Evolution' articles. This time, we're featuring the hyperactive, ravenous Roboreptile. As you will see, some of the mock-ups don't quite look the eventual product, but always interesting to see what was going through the minds of the designers.

By the way, if you haven't seen them, here are links to the first set of evolution articles: Roboraptor, Robosapien, Robosapien V2.  Also, the Robopet article.

[ Incidentally, you can click on the images for larger versions. ]


First off, the designers used real lizards as models for the Roboreptile. Makes sense!

Real Lizard

A real nimble lizard walking on water. No surfboard required...

Pencil Sketch

An early pencil sketch. The tail did some growing since then...

wireframe sketch

A Wireframe sketch. Hmm.. one of the joints in the back leg has since disappeared.



An early mock-up drawing. Boy, those claws look sharp.

Drawing 2

Another graphic mock-up. Way more colorful. Still looks like the legs have a lot of joints.

Drawing #3

Drawing #3. This reptile needs to get his bruised head examined.

Clay model

Clay-colored model. His neck still seems a bit short.


Early prototype

It may look like a prototype, but it's just a bunch of parts arranged on Mark's (Tilden) desk prior to construction. What's with the horns?

engineer at work

Interaction Designer, Alex hard at work, testing the interface and personality routines for bugs and accuracy. The Roboreptile is angry, because his back has been opened up.

black reptile

This poor reptile has his guts coming out of his back. Wouldn't it be cool to have an all-clear bot?


This is a 'proof of physics' sample built from CAD drawings for the legs and Mark's electronics. Even this early prototype without much of a body and gimpy legs had to be muzzled!


prototype 2

Engineers antagonizing an early prototype.

reptiles galore

Reptiles massed for attack!

final reptile

A finished Roboreptile sits calmly in his box waiting for his new victim, uh.. owner.

The End!
