If that dog, cat and fish just aren’t cutting it in the pet department, maybe you need something a little bigger. Featured at museums nationwide as part of a traveling exhibit, this motion-sensing, 20′ long Animatronic Triceratops responds to onlookers with lifelike reactions in the form of some major rumbles. Motion-activated cameras installed into each eye work in unison with customized interactive software that enables the Cretaceous creature to recognize multiple subjects’ facial features. Once identified, subjects’ tracked movements trigger a set of responses: it sways its tri-horned head right, left, up, and down, stomps and scuffs its right forelimb, and opens its jaws while growling–all powered by digitally controlled servos and silent, pneumatic air-activated cams. So basically, it scares the pants off of you and anyone else that comes its way.
