"A major milestone Geoffrey.  Great work.  You have a solid foundation for some serious indoor exploration autonomy.  Do let us all know how you get on with the white walls, low light and avoidance above/below.  I, for one, am…"

"@Hugues- Thank You, and you do bring up a good question. The prototype shown wasn't intended for commercialization, but more to see how far we can push vision at this scale. And that is only after a few months of tweaking that version so there…"

"Incredible! Very impressed. This has to be the future of drones because: -it is self-reliant (no dependencies on weather nor environment blocking GPS signals) -it is small and light. All regulations in all countries will let people fly drones freely…"

"@Fnoop- I agree. The near-Earth problem for drones is analogous to the "last mile problem" for the Internet that was a big focus of the 90's and 00's. The notional Amazon delivery drone can't rely on GPS to land on your…"

360 degree stereo vision and obstacle avoidance on a Crazyflie nano quadrotor

Posted on November 19, 2015 at 4:28pm 17 Comments

(More info and full post here)

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…

Visually stabilizing a Crazyflie, including in the dark

Posted on March 28, 2014 at 6:44am 10 Comments

I've been working on adding visual stabilization to a Crazyflie nano quadrotor. I had two goals- First is to achieve the same type of hover that we demonstrated several years ago on an eFlite 'mCX. Second is to do so in extremely low light levels including in the dark,…

What can bees tell us about seeing and flying at night?

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 …

Hardware Startup Groups Unite!

Recently I started the DC Hardware Startup meetup as a complement to the many Web 2.0-ish entrepreneur meetups in the DC area and elsewhere, and then reached out to the organizers of similar meetups around North America. Two are about a year old- the …

11 gram Arduino-powered laser rangefinder

Posted on June 29, 2012 at 1:49pm 20 Comments

I was pleased to see a cool laser rangefinding project on Kickstarter- I hope this project gets fully funded (and I'm a backer). I've actually been experimenting myself with structured light and laser rangefinding using our ArduEye hardware and thought I'd share it…

Thanks Geoffrey.

Hi Geoffrey I have a special MAV how hard is it to program your optic flow gizmos ?
At 7:29pm on March 2, 2010, Geoffrey L. Barrows said…
Bhargav- Do you mean integrate them with your system or actually program the devices themselves?

Hi Geoffrey, yes we have had a project on bridge inspection using the Infotron drone. You can find a little more information about the project here:

Your work looks pretty interesting too... I will have to have a look over it when I find some free time...

Best, Andrew
