5/2/2023 0 Comments Rocket copter review![]() It's all very intriguing, but what might the drone actually be used for? According to Rawashdeh (who previously helped bring us the Autobike), possible applications include search-and-rescue operations, bridge foundation inspections, underwater pipeline inspections, tracking of oil spills at different depths, and marine life studies. "For open-water applications, we can have the vehicle dive at predefined GPS points to various depths autonomously and follow some pre-programmed movement patters underwater to collect data or video footage." "We are looking into acoustic modems, repeater buoys, and some other techniques that could allow streaming of live video for operator feedback as well as data and control commands," lead scientist Dr. Down the road, however, all that could change. ![]() Its video also can't be transmitted topside, and is instead recorded onboard for subsequent viewing. In its current prototype form, the untethered drone's underwater remote control range is limited to a depth of a few meters. Once it's time to get airborne again, it just pumps out its buoyancy chamber, causing it to float back to the surface and swing into position. While it's underwater, it can turn to either side, dive or ascend using its water ballast system, and record video or gather other data as it does so. It then re-engages its props, allowing them to pull it top-first through the water. Instead of submerging straight down, the Loon actually tips to one side as it sinks. The real fun starts when it pumps water into its buoyancy chamber, though, causing it to sink. It can then simply sit in one spot, or it can use its props to push itself along the surface. ![]() ![]() The Loon flies in the same fashion as any other quadcopter, and initially floats when it comes to rest on the water. As is the case with its feathered namesake, however, Oakland University's Loon Copter can fly, land on the water to see what's under the surface, and then dive down to check out what it sees. Along with the usual flying drones, there are also models that can move along the surface of the water like boats, that can explore underwater like submarines, or that can even both fly and float. ![]()
