NAO’s walking uses a simple dynamic model (linear inverse pendulum) and quadratic programming. It is stabilized using feedback from joint sensors. This makes walking robust and resistant to small disturbances, and torso oscillations in the frontal and lateral planes are absorbed. NAO can walk on a variety of floor surfaces, such as carpeted, tiled, and wooden floors. NAO can transition between these surfaces while walking.

Since their inception in 1984 Kokoro have created various ‘ofrobots’ including people friendly vending machines, massive animatronic dinosaurs and life-like ‘humanoid’ robots, developed in ‘continous observation of humans’.
Kondo Robot announced a new, low cost, hexapod robot design with surprising flexibility, performance, and customizability. The robots unique leg design incorporates springs and linkages only requiring two servos per leg while improving the hexapod’s ability to deal with uneven terrain and obstacles. The robots base frames can be easily fabricated or modified by builders to realize custom configurations.
This robot was originally designed as a request from the creator’s son, which probably explains its simplicity. It is also very practical, and shows off its impressive movements in the beginning of the video (see the end of this post), especially when it doesn’t have a human to carry. Besides the before-mentioned scurrying of its legs, it doesn’t have any features designed to look like an insect, yet its biological-like gait is more than enough to give it a life-like spontaneity.
The Legged Squad Support System (LS3) is a rough-terrain robot developed by Boston Dynamics with funding from DARPA and the US Marine Corps. It is designed to carry 400 lbs of payload and travel 20 miles without refueling. LS3 has sensors that let it follow a human leader while avoiding obstacles in the terrain.
RHex is a six-legged robot with inherently high mobility. Powerful, independently controlled legs produce specialized gaits that devour rough terrain with minimal operator input. RHex climbs in rock fields, mud, sand, vegetation, railroad tracks, telephone poles and up slopes and stairways.
Honda Motor Co., Ltd. today unveiled an all-new ASIMO equipped with the world’s first autonomous behavior control technology. With a further advance in autonomy, the all-new ASIMO can now continue moving without being controlled by an operator.
AIST has succeeded in making HRP-4C Miim walk like a human being. Her knees are stretched by up/down motion of the waist, the single-toe supporting realizes longer strides, and she mimics the swing motion of human legs.
