A team at Sherbrooke University in Quebec has designed an autonomous fixed-wing drone that brings the best of bird technology to the UAV species.
Called S-MAD (Sherbrooke's Multimodal Autonomous Drone), the craft flies horizontally until its laser sensor detects on oncoming wall. At that point, the drone slows and tilts upwards, increasing its thrust as it gets closer to the wall.
Microfiber feet grab on to the wall's rough surface where the UAV can perch for as long as needed.
The Sherbrooke developers say the S-MAD's vertical perchability will find uses in building inspection, disaster areas, and surveillance.
