Legged robot tripod. Four-legged robots also benefit from a lower center of gravity than two-legged systems.

Their final designs often mimic the mechanics of insects, and their gaits may be categorized similarly. These include: Six-legged robots include: Eight-legged legged robots are inspired by spiders and other arachnids, as well as some underwater walkers. They offer by far the greatest stability, which enabled some early successes with legged robots. Eight-legged robots include: Some robots use a combination of legs and wheels.
