Honda Asimo robot runs round in circles at CES 2007

Honda began developing its humanoid robot in 1986. Its first self-regulating, two-legged robot was completed ten years later, in 1996, and christened P2. A year later Honda produced P3, the first completely independent, humanoid walking robot. The first Asimo (Advanced Step in Innovative Mobility) was completed in 2000, and the current model (new Asimo) took its first public steps in 2005.

Despite the humanoid appearance, there's something vaguely ducklike about Asimo's walk. It moves smoothly and changes direction without pausing, but its hips don't rise and fall with each step -- the walking action is almost entirely in its legs.
