Chicken walker

From Wikipedia, the free encyclopedia
Jump to: navigation, search

A chicken walker is a fictional type of bipedal robot or mecha, distinguished by its rear-facing knee joint. This type of articulation resembles a bird's legs, hence the name.[1] However, birds actually have forward-facing knees; they are digitigrade, and what most call the "knee" is actually the ankle.[2]

They are usually less able to handle extremely rugged terrain than "man walkers". They are often shown to be faster than other robots, capable of roadrunner-like movements. The best example of this contrast in film is the fast pursuits of the ED-209 versus the steady walking pace of RoboCop in the RoboCop franchise. Also, in the Star Wars franchise, the chicken-walking AT-ST was used as a light scout vehicle rather than the AT-AT, which were lumbering quadrupeds.
