There are many variations of Japanese robotics. Some different types of robots are: Humanoid Entertainment Robots, Androids, Animal (four-legged) Robots, Social Robots, Guard Robots, and many more. There are also a variety of characteristics for these robots.
The Robotics industry is more important in Japan than any other country in the world. Japan employs over a quarter of a million industrial robot workers. In the next 15 years, Japan estimates that number to jump to over one million and they expect revenue for robotics to be near $70 billion by 2025.
Androids are robots designed to strongly resemble humans.
Eventually the deeper long term financial resources and strong domestic market enjoyed by the Japanese companies prevailed, their robots spread all over the globe. Only a few non-Japanese companies managed to survive in this market, including Adept Technology, Stäubli-Unimation, the Swedish-Swiss company ABB (ASEA Brown-Boveri), the Austrian manufacturer igm Robotersysteme AG and the German company KUKA Robotics.
This includes the one used by the robot based automative production plants, known as assembly line robots.
A recently created robot called CB² or Child-robot with Biomimetic Body may follow moving objects with its eyes. CB² may recognize the human touch, which is possible thanks to the 197 film-like pressure sensors that are placed under its rubbery skin. Asada, the team of engineers and brain specialists together with psychologists and many other specialists in the related domain created a CB² that may record emotional expressions, memorize them and then match them with physical sensations.
The characteristics of robots are however progressive, their abilities being enlarged as the technology has progressed. The same CB² acts more and more as human and it was capable of teaching itself how to walk with the aid of human help. The robot learned how to move around the room by using its 51 "muscles," which are driven by air pressure.
The humanoid Japanese robots characteristics include abilities such as blinking, smiling or expressing emotions akin to anger and surprise. One of the newest Japanese robots, HRP-4C is a female-robot programmed to catwalk. It walks and talks and with the help of 30 motors it may move its legs and arms however loudly and awkwardly. The facial expressions that are capable of are driven by 8 facial motors to make it smile or blink and change the facial expression as a response to anger or surprise.
