Featured at museums nationwide as part of a traveling exhibit, this is the motion-sensing, 20' long animatronic triceratops that responds to onlookers with lifelike reactions and fortissimo bellowing. 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. Its exterior is crafted by professional sculptors from polyurethane foam and textured silicone over a steel and aluminum frame, replicating the beast's massive horned frill, powerful hindquarters, and tapered tail with convincing realism. The rumbles that issue from a hidden 1,000-watt speaker are based on paleontological approximations of what sounds the original 67 million year-old saurian might have vocalized. 20' L x 4' 7" W x 8' 6" H.
