Earthquake rescue robots have experienced their final tests in Beijing. Their designers say that with these robots, rescue workers will be able to have more time to save more lives during an earthquake.

This robot looking like a helicopter, is called the detector­bot. It’s about 4 meters long, and it took about 4 years to develop the model.   Its main functions (作用) are to collect information from the air, and send goods of up to 30 kilos to people stuck in an earthquake.

This robot has a high quality 360 degree panoramic (全景的) camera. It can work day and night and will also be able to send the latest pictures from the quake area. Dr. Qi Juntong, from the Chinese Academy of Sciences, said, “Unlike other automatic machines, the most important feature of this robot is that it doesn’t need a distant control. We just input the information of the earthquake­struck area to it, and then it   takes off, and lands by itself. It flies as high as 3,000 meters,   and as fast as 100 kilometers per hour.”

This robot has a different function — it can change as the   environment changes. Its main job is to search for any signs of   life in places where human rescuers are unable to go.

As well as a detector (探测器) that finds victims (遇难者) and detects poisonous gas, a camera is placed in the 4­meter­long robot, which can work in the dark.

Another use for the rescuers is the supply device, with its 10­meter­long pipe. People who are caught in the ruins will be able to get supplies including oxygen and liquids.

Experts have said that the robots will go into production,   and serve as part of the national earthquake rescue team as soon as next year.
