From the Problem Description: "Identifying technologies that can provide remote and rapid rescue support in search and rescue scenarios that put first responders in danger. Specifically, the ability to easily deploy unmanned systems that evacuate victims from hazardous environments (e.g., swift water, ice, active shooter, cliff-side environments) is key to decreasing injuries and death of emergency responders of all disciplines (i.e., law enforcement, fire, emergency medical services (EMS)) who often must respond to victims that are situated in difficult to reach or dangerous to enter locations. While the use of unmanned aerial, ground, and maritime systems is increasingly common in first responder scenarios, there are few examples of proven solutions that can extract victims autonomously or without manual assistance from rescuers. Many existing unmanned systems can help rescuers find and locate victims (e.g., using an Unmanned Aircraft Systems (UAS) to surveil large areas), but do not have the payload capacity or modular attachments to lift and transport victims."
