The Honda Motor Company developed ASIMO, which stands for Advanced Step in Innovative Mobility, and is the most advanced humanoid robot in the world. According to the ASIMO Web site, ASIMO is the first humanoid robot in the world that can walk independently and climb stairs.
In addition to ASIMO's ability to walk like we do, it can also understand preprogrammed gestures and spoken commands, recognize voices and faces and interface with IC Communication cards. ASIMO has arms and hands so it can do things like turn on light switches, open doors, carry objects, and push carts.
Engineers further refined ASIMO's motion system, boosting its walking speed from 2.5 to 2.7 kilometers per hour and giving ASIMO the ability to run at speeds up to 6 kilometers per hour. Honda increased ASIMO's height to 4 feet 3 inches (130 centimeters), and the robot put on a little weight, tipping the scales at 119 pounds. The engineers switched ASIMO's power supply to a lithium battery that doubles the amount of time it can operate before recharging. They also implemented the IC Communication card technology that helps ASIMO interact with people. New sensors allowed ASIMO to move in sync with people while holding hands.
