Drones and robots can go places that are not easily reachable or safe for humans. Take this flamethrower drone for instance. It is capable of removing objects around high voltage power lines, saving workers from having to climb a high ladder to remove them manually.
Workers in Xianniang City in central China’s Hubei Province used the drone to remove a 12-meter long nylon net on an UHV power line while staying on the ground. Spitting fire at it from 5 meters away got the job done in minutes.
