This letter reports the design, fabrication, and testing of lightweight whisker sensors intended for use on robotic platforms, especially drones, featuring multiple whisker fibers in an array. The whiskers transmit forces along the vibrissae fibers to a load plate bonded to embedded MEMS barometers
We propose a novel rotor safety mechanism for rotary-wing small unmanned aerial vehicles, such as quadrotors, that avoids problems associated with cages, rotor shrouds, and obstacle avoidance safety systems. The system works by using a passively spinning hoop as a mechanical interference sensor; cha
Trajectory tracking of micro UAVs requires accurate thrust and velocity estimates. High-quality motion control of quadrotors typically employs accurate high-speed optical sensing indoors. However, these measurements are not available outdoors, and GPS is unreliable and inadequate for performance mot
Quadrotors flying close to the ground experience a force resisting their descent known as ground effect. In this letter, we use ground effect to provide passive position stability of a quadrotor. We analyze stability of a quadrotor with canted rotors flying in a sloped ground channel. Flying a 200 g
