Geoffrey L. Barrows commented on Geoffrey L. Barrows's blog post Drone obstacle avoidance in 2003: 264 pixels and 8-bit processors
"@Andreas, I agree, and we are on the same page. An issue that can be faced is that some see the off-board mode as undesirable. Apparently the off-board mode bypasses all sorts of safeguards that some understandably want to keep. Therefore any…"

"@Andreas- You bring up some good points. I think that higher "D" avoidance systems are on the horizon, at least for larger drones, but once they are developed it will be quite awhile before they are plug and play. One of the points of my D/R…"

Geoffrey L. Barrows commented on Geoffrey L. Barrows's blog post Artificial insect intelligence and vision for nano drones - how many pixels do you actually need?
"Greg- Thank You. Yes, FPGAs can clearly have a place in such a system, as could highly parallel processing architectures, if done right. Things to keep in mind, though (and these are my opinions): 1) We have to remember that the mass of a processor…"

"Thank You Chris, both for the comment and the suggestions. I have not looked at OpenCV for a long time, and have not looked at TensorFlow Lite. I was not aware of the OpenMV board- this is pretty cool! I was actually moving somewhat in that…"

(Photo by Dustin Iskandar, CC BY 2.0)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…

Geoffrey L. Barrows commented on John C.'s blog post Parrot/Pix4D announce 2017 Climate Innovation Grant
"Very cool! I wonder if this area would benefit from yet smaller drones that can fly way up into the branches and see the structures from the inside."

Geoffrey L. Barrows commented on Chris Anderson's blog post Visual obstacle avoidance with Centeye and Crazyflie
"Chris, Everyone- Thank You for posting this. We are deliberately developing this technology for both civil and military use, and so I do envision this hardware finding it's way into, at least, commercial nano drones. The hardware can be made…"

Geoffrey L. Barrows commented on Colin Snow's blog post Why I Think the Prosumer Drone Will Never Die
"An inevitable implication of Zipf's Law is that if there is a market for a $100 version of a product, and a market for a $10000 version of a product, then there is certainly a market for a $1000 version as well. Also, if the market size (in units…"

Geoffrey L. Barrows commented on Simon D. Levy's blog post Hackflight Teensycopter
"@Patrick: Good question. We plan to reboot ArduEye sometime "soon". It was a mistake to stop it. As for the higher performance sensors for nano drones, we have a design that works great for internal development purposes.…"

Geoffrey L. Barrows commented on Simon D. Levy's blog post Hackflight Teensycopter
"Nice work Simon! I can appreciate your desire to have more control over the controller itself. We are happy with the Crazyflie, but that required us to build a separate controller board that generates all the high level control information.…"

Geoffrey L. Barrows commented on Chris Anderson's blog post RocketSpace/AT&T report on the future of drones
"Nice article! I pretty much agree with all of them, but some will occur sooner than others. I would like to add a few more predictions, based on observing the "micro" UAV industry since I first got involved in 1996:

11) Drones will fly close to the…"

"@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 is a…"

Geoffrey L. Barrows commented on Geoffrey L. Barrows's blog post 360 degree stereo vision and obstacle avoidance on a Crazyflie nano quadrotor
"@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 doorstep! We're not quite yet…"
