The School of Instrument Science and Engineering under Southeast University recently unveiled a remote nuclear and chemical detection and emergency robot that can assist humans in rescue missions in nuclear radioactive, poisonous and harmful environments.

The black robot is 30 kilograms in weight and 85 centimeters in height. This robot can mainly be used to perform tasks, such as measuring, sampling and on-site emergency treatments, at nuclear radiation, chemical and biological pollution sites where humans cannot approach or where the situation is not clear or highly dangerous.

The camera on the robot is resistant to radiation and the alloy aluminum armor is very rigid. A small nuclear detector within the robot can measure the amount of radiation in the surrounding area and it can also draw a graph indicating the radiation distribution. It can also find the point with the highest radiation intensity that is perhaps where the radiation source is located or the radiation leak point.

When it comes across radioactive sources in civic areas, the robot will use its mechanical arm to pick up the radiation source and put it into a thick lead box after it detects the most intensive point. If a radiation leak takes place at a nuclear power plant, the task of the robot is to detect the leak point and transfer the information back to related personnel. If the robot finds a loose valve, it can also tighten the valve.

"Normally, you can keep control of the robot remotely within a range of 5 kilometers, but in areas with high interference that may limit the robot's functions, you can keep control within a range of 1 kilometer," said Song Ai'guo, president of the Instrument Science and Engineering School.

Since 2004, Song and his team have developed five generations of robots. The latest fifth generation was developed in early 2011.
