Humanoid robots are created to imitate some the same physical and mental tasks that humans undergo daily. Scientists and specialists from many different fields including engineering, cognitive science, and linguistics combine their efforts to create a robot as human-like as possible. Their creators' goal for the robot is that one day it will be able to both understand human intelligence, reason and act like humans. If humanoids are able to do so, they could eventually work in cohesion with humans to create a more productive and higher quality future. Another important benefit developing androids is to understand the human body's biological and mental processes, from the seemingly simple act walking to the concepts consciousness and spirituality. Right now they are used for welding. In the future they can greatly assist humans by welding and mining for coal.
There are currently two ways to model a humanoid robot. The first one models the robot like a set rigid links, which are connected with joints. This kind structure is similar to the one that can be found in industrial robots. Although this approach is used for most the humanoid robots, a new one is emerging in some research works that use the knowledge acquired on biomechanics. In this one, the humanoid robot's bottom line is a resemblance the human skeleton.
The National Institute Advanced Industrial Science and Technology (産業技術総合研究所 Sangyō Gijutsu Sōgō Kenkyū-jo), or AIST, is a Japanese research facility headquartered in Tokyo, and most the workforce is located in Tsukuba Science City, Ibaraki, and in several cities throughout Japan. The institute is managed to integrate scientific and engineering knowledge to address socio-economic needs. It became a newly designed legal body independent administrative institution in 2001, remaining under the Ministry Economy, Trade and Industry.
