AI drones to the rescue: tackling wildfires with swarm intelligence

In the face of an escalating global crisis, where wildfires have become more frequent, larger, and more severe, a groundbreaking solution has emerged from the collaborative efforts of researchers and firefighters. Combining the power of artificial intelligence, computer vision, and swarm technology, a team of scientists has developed a innovative system of self-coordinating drones that can automatically detect, investigate and suppress fires before they spiral out of control.

 

 

The project, a partnership between the University of Sheffield, the University of Bristol, and Lancashire Fire and Rescue Service, represents a significant step forward in the battle against the devastating effects of wildfires. By leveraging the unique capabilities of these AI-powered drones, firefighters are now equipped with a powerful tool that can significantly enhance their ability to respond to and mitigate the impact of these natural disasters.

"Autonomous wildfire detection and localization, especially in remote and large geographic areas, with hot weather is a challenging task that has not been fully achieved yet with the current technology," explained Dr. Lyudmila Mihaylova, Professor of Signal Processing and Control in the School of Electrical and Electronic Engineering at the University of Sheffield. "At the University of Sheffield, we have been developing AI and Computer Vision approaches able to work under different weather conditions and by extracting efficient image information from the incoming video data."

The key to the system's effectiveness lies in its ability to seamlessly integrate AI technology with thermal and optical imaging, enabling the drones to automatically detect and investigate fires, and relay all the critical information to the fire teams on the ground. But the true innovation lies in the swarm technology developed by the University of Bristol, which allows the drones to self-coordinate as first responders, rapidly deploying fire retardant onto the blaze, monitoring the situation, and returning to base as needed.

"Although autonomous singular drones have been partially used in firefighting, the swarms' technology provides a higher level of efficiency and trustworthiness," Mihaylova said. "The technology can lead to a step change in wildfire tackling operations and equips firefighters with powerful tools for remote tackling of propagating fires."

This innovative approach has already caught the attention of Lancashire Fire and Rescue Service, which has put the system to the test as part of its efforts to develop cost-effective early mitigation strategies for wildfires. In 2018, the service spent 41 days battling a wildfire that had spread across 18 square kilometers of moorland near Bolton, a testament to the challenges faced by firefighters in the face of these rapidly escalating events.

"The earlier we reach fires, the less harm they pose to firefighters, communities, infrastructure and the environment," said Lancashire Fire and Rescue Service's Chief Fire Officer, Justin Johnston. "This technology has the potential to revolutionize the way we approach wildfire management, giving us the ability to detect and respond to these threats before they spiral out of control."

At the heart of the system are the Windracers ULTRA self-flying cargo aircraft, which can autonomously carry up to 100 kg of fire retardant and cover vast areas in search patterns during the summer months. These drones, which have previously been used for scientific data collection in Antarctica and parcel delivery in the Orkney Islands, are now being repurposed to serve as the first line of defense against the growing threat of wildfires.

"The swarms' technology provides a higher level of efficiency and trustworthiness," Mihaylova emphasized. "The technology can lead to a step change in wildfire tackling operations and equips firefighters with powerful tools for remote tackling of propagating fires."

As the effects of climate change continue to exacerbate the wildfire crisis, the development of this innovative AI-powered, self-coordinating drone system represents a significant breakthrough in the quest to mitigate the devastating consequences of these natural disasters. By leveraging the latest advancements in technology, the researchers and firefighters involved in this project are paving the way for a future where wildfires are detected and suppressed before they have the chance to cause widespread destruction.
