Through the introduction of foreign nuclear radiation detection technology and robot radiation protection technology, a detection and operation robot in nuclear radiation environment is developed. It adopts six wheel car body design, has large load and strong obstacle crossing ability. It is equipped with double camera system, 360 degree remote monitoring, reliable and long communication distance (more than 200 meters), normal operation, independent detection of nuclear radiation source orientation, positioning accuracy ± 5 ° and real-time fast Fast detection of radiation dose. And equipped with 6-axis manipulator for flexible remote control operation. The robot technology can be widely used in the fields of nuclear technology utilization industry radioactive source detection and accident disposal, nuclear power plant industry detection operation and nuclear facilities decommissioning, and military nuclear, chemical and anti-terrorism.
