One of the world's largest package delivery companies is stepping up efforts to integrate drones into its system. UPS has partnered with robot-maker CyPhy Works to test the use of drones to make commercial deliveries to remote or difficult-to-access locations. The companies began testing the drones on Thursday, when they launched one from the seaside town of Marblehead. The drone flew on a programmed route for 3 miles over the Atlantic Ocean to deliver an inhaler at Children's Island. The successful landing was greeted by jubilant shouts from CyPhy Works and UPS employees on the island to witness the test. "I thought it was fantastic," said John Dodero, UPS vice president for industrial engineering.
