The Roboreptile is a toy robot by WowWee. The Roboreptile has infrared and sound sensors, and is able to autonomously explore its environment while avoiding obstacles. It can also operate in different modes where it simulates behaviors of real animals. It is able to rear up on its hind legs and attack. Roboreptile was released in China on the 28 April 2006 and to the rest of the world later that year. It is superficially similar to a theropod or a prosauropod dinosaur but being quadrupedal it's better equated to a silesaurid or a monitor lizard.
