Today it is universally acknowledged that drones operating close to the ground need some sort of obstacle avoidance. What I am about to tell is the story of our own…Continue

My long-time interest has been in developing insect-type vision for small drones. Properly implemented, I believe that such vision hardware and algorithms will allow small drones to fly safely amidst clutter and obstacles. Of course, I have been following with great interest other approaches to providing…Continue
I've been experimenting with putting 360 degree vision, including stereo vision, onto a Crazyflie nano quadrotor to assist with flight in near-Earth and indoor environments. Four stereo boards, each holding two image sensor chips and lenses, together see in all directions except up and down. We developed the image sensor chips…Continue
How would you like your drone to use vision to hover, see obstacles, and otherwise navigate, but do so at night in the presence of very little light? Research on nocturnal insects will (in my opinion) give us ideas on how to make this possible.
A recent …Continue
