Background technology
Anthropomorphic robot, also known as anthropomorphic robot, is tool robot anthropomorphous.Appearance is named as " An Deluoding " (android) as the machine of people by Sade rel Adam in 1886 in his novel " following Eve ", is exactly a kind of anthropomorphic robot.Describe according to rel Asia, anthropomorphic robot is made up of four parts: life system (balance, walking, sounding, body swing, sensation, expression, adjustment movement etc.); Moulding solution matter (the free-moving metal nappe of closing energy-saving, a kind of armor); Muscle (having the various forms of the healths such as the human body, vein, sex on the above-mentioned armor); Artificial skin (containing the colour of skin, profile, hair, vision, tooth, paw etc.).
The multi-door subjects such as anthropomorphic robot integrates mechanical, electrical, material, computer, sensor, control technology are the important symbols of a national high-tech strength and development level, therefore, World Developed Countries all do not stint drop into huge fund develop research.A large amount of work has all been done in development humanoid robot by Ying Deng state of Japan and the United States, and the progress of making a breakthrough property.
Japanese honda company is proposed humanoid robot P3 in October, 1997, Massachusetts Institute Technology have developed humanoid robot section dagger-axe (COG), Germany and Australia have developed jointly is equipped with 52 cylinders, the heavy-duty machines people of height 2 meters, body weight 150 kilograms.The novel robot " ASIMO " of Honda Company's recent development, height 120 centimetres, body weight 43 kilograms, its mode of walking is more close to people.
Massachusetts Institute Technology have developed a kind of novel robot having eyes as people, and it can exchange with the mankind, can give a response the environment of surrounding, and the mankind can be assisted to complete much work.China has also done a lot of work in this respect, and the National University of Defense technology, Harbin Institute of Technology have developed bipod walking robot, and BJ University of Aeronautics & Astronautics, University of Science & Technology, Beijing have developed multi-finger clever hand etc.
On June 16th, 2010 Tokyo Univ Japan and the computer MSR Information system of Osaka University composition to public display a simulated baby robot, it is exactly a up-to-date anthropomorphic robot.Baby doll's height 71 centimetres that this is named as " wild tail ", has 600 sensors below the simulation skin of softness, can make stretch out one's hand, the action such as rotary head.When being embraced, the oxeye that flashes look at the world curiously, very lovely.
