Fog robotics is like using a robot to make a foggy environment. It is like having a robot sprinkler! The robot has a nozzle that sprays a mist of tiny tiny particles of water into the air. When the mist is in the air, it bounces off of things and makes it all foggy. This fog can be used to help people navigate when they can't see the ground clearly, like in the dark, or in a smokey room.
