Robots are already being used to put out dangerous fires and save lives. Take the Colossus for instance: it is a robotic firefighter that can put out strong fires without putting human firefighters in danger. It has a payload capability of 550kg and lasts up to 12 hours on battery.
The robot has a modular design and can be used to carry a water cannon, transport tools, and move wounded people. The Colossus can go as fast as 3.5kh/h and handles slopes up to 45 degrees.
