A new concept for the military drone of tomorrow is out, and it’s basically what the fantastical writers of Chitty Chitty Bang Bang dreamed up a half century ago—only exceedingly more sleek, stealthy, and human-free than the magical vintage car.The proposed drone is called the Multi-Modal Vehicle Concept, developed by the government-funded Sandia National Laboratory. The defense science agency recently published a conceptual design video of the transformer drone in action, which was unearthed today by Wired.As you can see in the video, the multipurpose UAV flies, swims, and hops through obstacles by shedding and growing parts along the way. Wings transform into fins if the 'bot dives undersea, and then are swapped for wheels when it emerges onto the shore. The semi-autonomous vehicle can be controlled remotely to travel through varying terrain to complete a complex mission—say, special ops, rather than having to deploy an entire team.You may remember Sandia, which specializes in nuclear research, as the agency that recently pitched the terrifying idea of a nuclear-powered drone, which could fly for months without needing to refuel. That one’s had some difficulty taking off; the project is on halt while experts figure out just how wrong things could go.This latest project, however, comes out of its Intelligent Systems, Robotics and Cybernetics unit. "ISRC has built and conducted limited testing on conceptual hardware, and while the concept may appear to be off in the distant future, our testing has shown that this concept could soon be a reality," the website states. Sandia is raising funds to build the first prototype and introduce the futurist drone to the industry.
