Cool drone lands on walls

FOX News

A new drone prototype has the ability to not only take off and land vertically, but it can also land against a wall, similar to a bird. The Multimodal Autonomous Drone (S-MAD) was created by researchers at Canada's University of Sherbrooke, utilizing microspineso to allow it to attach itself to these kinds of surfaces. "Microspines are used to cling to rough walls, while strictly onboard sensing is used for control," a paper on the drone reads. "The effect of thrust on the suspension's landing envelope is analyzed and a simple vertical velocity controller is proposed to create smooth and robust descents towards a wall."
