Analysis of cognitive skill in a water discharge activity for firefighting robots

Abstract Teleoperated robots are expected to perform tasks in unexpected disaster sites, which have become increasingly common recent years. However, only few teleoperated used for such purposes owing their poor usability compared the handling of by humans. Further, human-machine interfaces (HMI) closely related human skills. Firefighting activities require cognitive skill make appropriate decisions. In extinguishing a fire or attenuating leaked combustible gas, firefighting consist two tasks: reconnaissance and water discharge stop attenuate these possess different properties. this study, we ten firefighters (five novices five experts) latter said tasks, using robot at department. The experimental results indicated that experts were more multifaceted evaluation attenuation gas as novices. addition, result firefighter decision-making mechanisms, motivated improve HMI robots.
