When an earthquake, fire, avalanche, or other disaster occurs, search and rescue dogs play an irreplaceable role in rescue operations. But when rescues dogs are tethered to people, their mobility is limited, hampering the speed at which they are naturally able to search for survivors. The Rescue dog companion-2 greatly improves the search efficiency of rescue dogs and enhances the communication between rescue dogs and workers. Through this wearable intelligent device, rescue dogs can search independently. When a dog finds a survivor, it barks, and the rescue team automatically receives positioning information and a rescue route.
