53 unmanned systems inside June/July 2016 ENGINEERING. PRACTICE. POLICY. Bayat said. "[Our] robot is very much con- strained by the battery. We have to use as little energy as possible but still manage to cover as much area as possible." Dunk Resistant Finally, an idea that deserves honorable men- tion in the category of amphibious drones is nei- ther amphibious or a drone. But, Indiana-based DroneRafts's first product, the WaterStrider, is designed to make using drones around water much easier and safer. WaterStrider is a snap-on set of lightweight (about a half-pound) pods for the Phantom 3 and 4 UAS that make the vehicles look a little like those water strider bugs that can glide across the surface of a lake. The pod feet mean pilots can better avoid dunking their Phantom in a lake while trying to get that perfect shot. (It also makes it easier to land on rocky terrain.) DroneR af ts launched WaterStr ider on Kickstarter April 22 and met its $22,500 funding goal by May 28. A Unique Combination The potentia l for water-to -air-to -water drones is enormous. Though many platforms remain untested outside the laboratory, with so many possible uses, it's not surprising that a number of teams are working to develop these concepts. "I think in people's minds, air and water was not compatible," said Rutgers' Diez, add- ing that a NASA scientist couldn't believe the Naviator could perform until seeing it with his own eyes. "I think our accomplishment was to break that barrier." "YOU CAN ACTUALLY DO A LOT MORE operations underwater if you are neutrally buoyant; you can spin on all your axes."
