A domestic think tank has developed robots to respond to a nuclear disaster.
The Korea Atomic Energy Research Institute (KAERI) on Dec. 7 said it developed an unmanned robot system that responds to such a contingency.

Under the system, robots instead of human personnel are dispatched to the site of a nuclear disaster given the threat of a radiation leakage.

The system is composed of the robots TRAM (Tracked Radiation Area Monitoring), which monitors indoor areas, RAM (Remote Control System for Accident Monitoring), which conducts surveillance outdoors, and ARMstrong (Accident Response Manipulator), which responds to a disaster.

TRAM is a small armored vehicle about 30 cm tall that detects radiation and temperature. In real time, it creates a 3D map, outlines information such as the radiation level at the disaster site and thermal imaging, and transmits this data externally.

RAM, a drone that monitors radiation in midair, can fly 60kph and create a map of radiation contamination based on field observations of the site.

ARMstrong can carry cargo of up to 200 kg and freely travel on rough terrain. It can also transport concrete and waste drums, spray water to extinguish fires and handle debris.

Since 2016, KAERI has verified the efficiency of these robots in disaster simulations. In August this year, it sent TRAM inside a building to gather information about the situation there and in October, ARMstrong was dispatched to spray urethane foam that sealed off all entry and exit points of a radiation-leaking building.
