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

This robot looking like a helicopter, is called the detector-bot. 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 trapped by an earthquake.

This robot has a high definition 360 degree panoramic (全景) camera. It can work day and night and will also be able to send the latest pictures from the quake area.

Dr. Qi Juntong, Chinese Academy of Science, said, “The most important feature of this robot is that it doesn’t need a distant control. We just set the destination (目的地) information on 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 and detects poisonous gas, a camera is placed in the 40 centimeter long robot, which can work in the dark.

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

Experts have said that the robots will enter production, and serve as part of the national earth-quake rescue team as soon as next year.
