When it comes to emergencies, first responders don't have much time to think, whether it be a fire or search-and-rescue mission, and that's why Switzerland-based Fotokite has developed a fully autonomous tethered drone. Called Sigma, it was built using the NVIDIA Jetson platform and specializes in covering the vast majority of situations where first responders need an aerial perspective during an emergency. Not just a standard autonomous drone, this one comes equipped with a thermal camera capable of determining where a fire is, as well as where the safest location to enter or exit a structure would be. The drone can automatically highlight hotspots that need attention and guiding firefighters on where water is needed most, even through heavy smoke or with limited visibility. Everything from autonomous flight and real-time data delivery to the user interface and real-time streaming is made as simple as pushing a button, which means first responders can focus on saving lives and keeping people safe.
