Drones

A new dual drone can both fly and land on water to take aquatic samples and monitor water quality, for example. The drone was developed by researchers at Imperial College London and Empa and recently tested together with researchers at the aquatic research institute Eawag for the first time on Lake Zurich.

Engineers at EPFL and ETH Zurich developed a variable stiffness catheter made of nontoxic threads that can transition between soft and rigid states during surgery. It may make minimally invasive surgical interventions, including the treatment of cardiac arrhythmia, simpler and more effective.

Engineers at EPFL have developed a predictive control model that allows swarms of drones to fly in cluttered environments quickly and safely. It works by enabling individual drones to predict their own behavior and that of their neighbors in the swarm.
