UPS has begun testing emergency drone deliveries with Massachusetts-based CyPhy Works, a drone company that the shipping giant invested in last year. The companies tested the 3-mile delivery of an asthma inhaler last week. “The CyPhy-UPS drone, called the Persistent Aerial Reconnaissance and Communications drone, or PARC for short, was autonomous during the flight and navigated by GPS,” reports Digital Trends. The drone features “a high-resolution camera with thermal imaging and target tracking abilities, and two GPS units and multiple rotors, antenna and communications systems.”
