BEIJING - A team of Chinese engineers has designed an intelligent robotic car that can clean, repair and complete replacement work on the country's Five-hundred-meter Aperture Spherical Radio Telescope, the world's largest single-dish and most sensitive radio telescope.

The newly-developed robocar is capable of running in all directions and fulfilling replacement tasks automatically even on a 56-degree steep slope, according to the Institute of Automation under the Chinese Academy of Sciences, which designed the robot

Maintaining 2,225 laser targets on a giant spherical dish with a receiving area equivalent to 30 football fields is quite a challenge. The telescope's reflective surface is made of one-millimeter thin aluminum plates, making them unable to bear the weight of a normal adult.
