Berkeley researchers design self-folding in-flight drone arms
Posted by Shubham Ghosh Roy in categories: drones, education
Researchers at UC Berkeley have developed a drone whose hinged arms can fold themselves from horizontal to vertical position in order to pass through tight spaces or carry light objects.
Previous limb-adjusting vehicles created by labs like Purdue University’s Engineering Technology school were outfitted with actuators that shifted the arms and rotors into different positions, making them more efficient in certain conditions like heavy winds. The HiPeRLab staff wanted to avoid inclusion of actuators, which draw off the drone’s batteries and thereby reduce its flight time. Their solution: use passive hinges whose up and down folding is powered by the rotors themselves.
