A new method for controlling groups of drones, technically known as unmanned aerial vehicles (UAVs), could make formation flying smoother and reduce energy consumption and mechanical wear, according to research in the International Journal of Systems, Control and Communications. The work combines fuzzy logic processing with a self-adjusting control system, known as a self-coupling proportional-integral-derivative (PID) controller.

A team of University of Toronto Engineering researchers has developed a flexible foot pad for the "Hopcopter"—a one-legged, hopping robot they developed—significantly enhancing its performance on sand, ice and other difficult terrain.
