γ Ray irradiation test of control system of nuclear emergency rescue robot

In past 40 years, robots have been proved necessity in nuclear crisis and daily maintenance. Especially after the Fukushima nuclear crisis, robots were used to detect irradiation dose rate and sample contaminated water inside the reactor more widely. The key for a nuclear robot was irradiation hardness of its components, especially the electrical components. We conducted a yray irradiation test for the robot control system based on the previous works of the motion control subsystem. The result showed the control system and communication link survived under 100Gy, then we took an additional 300Gy total dose test and found the value of total dose under which made system the catch is incapable. Based on the results and future work, it is possible to design a control system that can survive under 100Gy.
