"Actually, 3D-printing them works quite well !"

We wanted to share a fun video we made recently. Our drones can interact with obstacles and humans, which is opening amazing new applications, be it for accessing hard-to-reach places or for having fun with them. We achieve that through a passively…

AdrienB commented on Trent at MyGeekShow's blog post MyGeekShow - Building the Solar UAV Prototype
"Check out the thesis of André Noth: http://www.asl.ethz.ch/research/asl/skysailor (link to pdf at bottom).
His solar plane flew successfully for 27 hours straight. Tons of great information for you in there !Best,Adrien"

AdrienB commented on Chris Anderson's blog post Autonomous ball drone bounces off anything
"Ahah, I'm sure GimBall would enjoy meeting its Japanese counter part. 
One thing we realized however is that adding a fixed protective cage cannot prevent a crash in many situations, because of the torque that may put the platform in an unstable…"

AdrienB commented on AdrienB's blog post Calibrating the viewing direction of optic-flow sensors
"Hi Randy,
Thanks for the feedback!
The choice for the focal length of your lens really depends on a lot of things. To name a few:
- Amount of light in the environment. A bigger zoom usually means that the sensor gets less light. In my application, I…"

"@Ruwan: Were you presenting anything flying-related ?
@Geoffrey: Thanks for you comment ;)"

Members of DIY Drones using optical flow sensors, such as the ADNS3080 that is available in the DIYDrones store, or the Centeye vision sensors might be interested in the work I presented last week at ICRA. The method, described in the video above,…

AdrienB commented on Geoffrey L. Barrows's blog post RC micro helicopter hover (yaw and height) using millimeter thick vision camera
"Thanks for the answer Geoffrey !
And what about lateral control ? Here I assume that it's the passive stability of the coax that keeps it roughly in the same position (?). Could you use a similar vision-based technique to control the lateral motion…"

AdrienB commented on Geoffrey L. Barrows's blog post RC micro helicopter hover (yaw and height) using millimeter thick vision camera
"Hi Geoffrey,Thanks for sharing! Your work is very interesting. I'm impressed by the stabilization and how it only uses the small vision sensor. No inertial sensor is even required ? I wonder if you have to make assumptions about the environment…"

AdrienB commented on Geoffrey L. Barrows's blog post Micro Helicopter Hovering in Place Using Vision Sensing
"Wow, impressive results!
How comes I can't see any optics in front of the sensors actually ?"

AdrienB replied to William Premerlani's discussion robust estimator of the direction cosine matrix
"Hi,

Thank you for the interesting algorithm, and for all the detailed information given in the comments !

I think the compensation of the centrifugal force is very promising, and I wanted to understand a little bit better how you implemented it…"
