Since nuclear radiation is extremely harmful to the human body, detection personnel cannot enter the central area of ​​nuclear contamination for investigation. They can only enter the nuclear contaminated area through remote-controlled robots to collect on-site data;

[0003] After searching, it is found that the authorization announcement number is: CN216991931U, which is a nuclear radiation detection robot. Although the robot has the advantages of more comprehensive sampling data, which is more conducive to fully understanding the environmental conditions inside the nuclear contaminated area and providing first-hand information for command decision-making, the robot is easily affected by obstacles such as gravel in the area during detection due to environmental influences. The movement of the robot is easily affected, which not only easily affects the detection efficiency of the robot, but also increases the detection burden.

[0004] Therefore, a nuclear radiation detection robot is proposed to solve the above problems. Utility Model Content
