Raptor-1

   

   This is my first successful biped. I built 
   
   the main chassis first and added the dinosaur
   
   "bodywork" later. The design is based on a  
   
   velociraptor and is non-c.o.g.-shifting with 

   one motor. As with all my other bipeds, I 

   engineered the walking mechanisms myself. The 

   robot is 20" long and weighs 10.8 oz. Its 

   walking motion is pretty smooth and its speed 

   is approximately 3 feet/min.
