Earlier this month, China unveiled its first unmanned remotely operated robot that can help emergency responders operate in areas that have been contaminated with radiation, poisonous gases, or other dangerous chemical substances; the robot is outfitted with a slew of sensors that allow it to take samples, measure radiation levels, and analyze chemical and biological substances; the robot is particularly suited to operating in highly radioactive environments as it is equipped with a camera that is resistant to radiation and a nuclear detector that measures the amount of radiation in an area and draws a graph to help workers find the source of radiation
