A 1.6-meter tall robot may soon become the best friend for lonely elderly people，as Chinese scientists are making the final sprint(冲刺)toward its market launch(市场投放)，said a senior researcher on the robot project on Saturday.

“We are working on testing the exact functions and ways to reduce the cost in preparations for an expected market launch of the robot in two to three years，”said Li Ruifeng，a member of the project.

He said the team hoped to reduce the cost so that the robot can be priced at 30，000 to 50,000 yuan，which is expected to be an affordable price for most of China’s better-off families.

The robot has been developed with the functions of fetching food，medicine，sounding alarms in case of water or gas leakage，sending texts or video images via wireless communications，and even singing a song or playing chess to entertain its masters.

Li said that the robot，developed independently in China, has technology at the same level as those in western labs.
