ALBUQUERQUE, Aug. 16 (UPI) -- U.S. researchers say they're developing a rescue robot that could reach trapped miners while dealing with obstacles such as rubble piles and flooded chambers.
In a mine rescue attempt, humans face dangers like poisonous gases, flooded tunnels, explosive vapors and unstable walls and roofs that can slow rescue efforts to a frustrating pace, scientists at the Sandia National Laboratories in Albuquerque say.
