Yahoo says that Japan's top carmaker, Toyota plans to develop a humanoid robot by 2005. Toyota says they will give more details in January and hopes to display the robot at a World Exposition tradeshow in 2005. Toyota's robot will be a worker robot and built for "practical" purposes. A tall order for the robot includes nurse duties, factory work assistance, and rescue operations. Toyota even has plans to sell the humanoid robot, unlike some other Japanese companies that just build humanoid robots as test platforms and audience entertainers. Toyota even hopes to apply some of the newly developed technology to their cars.
