Wasp-inspired drone drags 40x its own weight though complex environments

US and Swiss researchers have created a miniature multi-mode drone that can act as a tug, dragging 40 times its own body weight over obstacles – while helicopter-style aerodynamic lifting would only allow ~2x to be moved. Called FlyCroTug, its operation was partially inspired by wasps. “Wasps can fly rapidly to a piece of food, ...
