NOTE: IRZ = In Robot Zoo and IRL = In Real Life
IRZ: Using real-time color image processing, visitors at three computer stations can “paint” colored patterns which appear almost instantaneously on the robot chameleon to demonstrate the lizard’s color-changing ability.
IRL: The chameleon can fire its long, sticky-tipped tongue to sharp-shoot insects in one sixteenth of a second.
IRZ: Pivoting visual sensors replicate the real reptile’s eyes which can move independently about 180 degrees in almost every direction.
IRL: To reel in a meal, a chameleon’s tongue muscles squeeze tightly around a long, thin bone in the floor of the mouth, shooting out the tongue to almost twice the lizard’s length.
IRZ: When the robot snags its prey, a spring-loaded mechanism triggers the coil (tongue) to shoot forward, like an orange seed squeezed between your fingers.
