A robot giraffe welcomes visitors to The Robot Zoo . A large piston holding the neck onto the shoulder copies the real animal's powerful neck muscle. Giraffes are the tallest animals on Earth. A giraffe's neck has seven bones, as many as a human's but each bone is a foot long. The whole animal is flexible enough for a giraffe to scratch its back with its nose.
Giraffes roam the savannas of Africa in loose, open herds of females and youngsters.
A giraffe uses its 18-inch tongue to pluck leaves from between thorns of acacia trees. The robot platypus forages for food under the water alongside a riverbank. Environments above and below the water's surface are visible, including a robotic dragonfly buzzing above the submersed robot. The robot's snout has sensory endings that can find food both by touch and by picking up electrical impulses from its prey. The webbed front feet of the robot have two roles.
