New Drone System Mimics ‘Nervous System’ for Extended Flight Endurance

Scientists are evaluating an innovative drone design engineered to extend operational duration in flight, attributed to its incorporation of a proprietary “nervous system.” Presently, drones designed for cargo transport necessitate frequent ground stops for manual safety inspections, a requirement that restricts their utility and elevates operational expenses. However, specialists at the University of Southampton have engineered a drone featuring an optical fibre system, which, according to researchers, is capable of self-monitoring its condition akin to the human body’s nervous system. The development team stated that this technology is expected to enhance the reliability and cost-efficiency of future drone operations. This system employs a distinctive method known as optical speckle, which projects particular images based on the input received by the optical fibre “nervous system.” These images can then be analyzed by AI algorithms to evaluate the drone’s structural integrity, as explained by Dr. Chris Holmes, a principal researcher on the project. “This speckle system keeps track of the stresses and strains on the drone, helping ground crews spot issues early without needing to land the drone as often for inspections,” he stated. Furthermore, he noted that the drones’ reliance on light for data transmission, instead of electricity, enables them to circumvent the radio frequency interference commonly encountered by electronic systems. The optical fibre system has already demonstrated encouraging results during trials conducted on a drone designed by undergraduate students at the university. Toby King-Cline, 23, an aerospace engineering graduate who headed the student team, commented that this technology has the potential to transform drone applications across numerous industries and expressed enthusiasm about observing the real-time data from the fibre system. “It showed that the technology could keep drones operational longer without the need for extensive ground crews,” he remarked. Dr. Holmes indicated that the objective is to commercialize this technology by 2025.
