Robots at the World Expo 2010 Shanghai play football，practice tai chi , play the violin, prepare Chinese dishes and care for the elderly. Scrap metal robots created by a Chinese farmer can pour tea and paint pictures.
Global designers of robots are making them more capable, powerful and affordable, so they will play more roles in more sectors, from manufacturing to health care, and they can help around the house.
Now Toyota, the world's biggest car maker, and Canon, the biggest camera maker, have joined research and development to make robots a practical reality, like a PC.
The Expo Shanghai is a place where China can learn about advanced robotics, and a stage for made-in-China robots.
Developers are taking robots from “Star Wars”and top laboratories and putting them into the industrial sector, even in consumer markets. They are used in health care, computer programming, manufacturing and culture.
The goals are to add more practical functions and to cut prices, and lower cost comes with higher volume.
“The World Expo is a unique opportunity to demonstrate French technology，”says Bruno Maisonnier，chief executive of Aldebaran Robotics, which shows Nao robots in the France Pavilion.
More than 700 Nao robots, which cost 1,000 to12,000 euros (US $ 14,640) each, are sold mainly to research organizations, including 60 to 70 in China.
The French-based company aims to promote robots in the general public market starting from late2011，with entertainment or learning functions at a"reasonable price", according to Maisonnier.
Visitors to the Japan Pavilion are struck by Toyota's dextrous Partner Robot playing the Chinese folk song Jasmine Flower on the violin. Other robots play other instruments, but the violin is the most complicated.
Many people were so enchanted by the robotic musician that they overlooked other Partner Robots, designed to be personal assistants especially for Japan's aging population. One can even carry passengers.
