Pivotal visual sensors replicate the real reptile's eyes that can move independently about 180 degrees in almost every direction. Chameleons are a highly specialized group of lizards, well adapted to life in the trees. When not in use, it curls up out of the way. Two metal horns on the robot simulate real rhinos strong horns. Shock-absorbing pads and flared supports on the robot's feet help bear its weight.
White rhinos are the second-biggest land animal.
They belong to a group of hoofed animals called ungulates, and in Africa the rhino's closest relative is the zebra. A rhino's horns are made out of hair-like fibers stuck together with a type of natural resin like glue. Flattened feet and broad, three-toed hooves distribute the rhino's massive weight over a large area. At twilight this insect-eating robot bat hangs from a tree, waking to go out on its nightly forage for food. Visitors can hear the ambient night sounds of crickets, other insects and birds in the distance.
