Army looks to improve quadrotor drone performance

When an aircraft veers upwards too much, the decrease in lift and increase in drag may cause the vehicle to suddenly plummet. Known as a stall, this phenomenon has prompted many drone manufacturers to err on the side of extreme ...

System prevents speedy drones from crashing in unfamiliar areas

Autonomous drones are cautious when navigating the unknown. They creep forward, frequently mapping unfamiliar areas before proceeding lest they crash into undetected objects. But this slowdown isn't ideal for drones carrying ...

Robotics

Adaptive locomotion of artificial microswimmers

Bacteria display remarkable plasticity by exploiting mechanics in response to locally changing physical and chemical conditions. Compliant structures usually assist their taxis behavior to navigate inside complex and structured ...
