Japan invented many rescue robots, and most of them survived the earthquake and other natural disasters.
The tracked rescue robot invented by the Metropolitan Police Department in Yokohama, Japan, can directly swallow people into the machine and take it away from danger zones, effectively reducing casualties by 60 percent. Because the entire robot was just like a rectangular box when it was first developed, this robot was also called a track coffin. After various tests and improvements, it added cameras, robot arms, and various sensors, including the "coffin." The sensor inside can also detect the wounded. Later, because the rescue effect was significant, many Japanese fire brigades, security departments, etc. were equipped with this robot. The robot that appeared near the nuclear reactor after the nuclear leakage of Fukushima in Japan was changed based on this robot.
In addition, in order to prevent crawler-type rescue robots from being able to drill into narrow crevices, Japan has also invented snake-like robots to work with them, which has greatly improved the progress of various rescue operations.
