Jason Short and I had a great day of flight testing yesterday after the rains cleared in Point Richmond, across the Bay from San Francisco. We were testing the 2.5 code on a range of different hardware (RC systems, ESCs, GPSs and airframes) to catch incompatibilities. The good news is that we found lots of them! (that's the bad news, too).
These are the bugs found:
--When ArduPilot is pulsing the servos after it's got GPS lock with the…
After much discussion about my poor effort to turn a military Reaper into a NASA Ikhana, IKE took the initiative to do it right and go straight to the source. He took a Ikhana photo, flipped and tilted it so it was…
You might have heard last week about Flyfire, a MIT concept that would use hundreds or thousands of little coaxial helis with LEDs to create a 3D screen in the sky. There was some confusion and the video was pulled, but now it's back and you can see what all the fuss is about. Pretty cool concept.
Having run this site for a few years now, I'm all too expert on the first reaction of newbies. Some of them I understand, some continue to mystify me. Here are the top five:
1) I want a helicopter to fly by itself! Can you help? We get this one daily. I don't really understand why. Perhaps it's because helis are so hard to fly manually? At any rate, most of these folks don't stay long. As the regulars here know, helis are the hardest autonomy challenge there is,…
Following the great example of the UAVDevBoard team, who have excellent documentation on their Google Code wiki, we'll be moving all the DIY Drones product documentation to Google Code wikis for each product.
If you're posting a blog post you'll note that the formatting tools are now much more powerful, allowing for WYSIWYG text and photo entry. No excuse for not having photos, videos and other eye candy! (Seriously, it's a very good idea to start your post with a relevent photo, which hugely increases click-through rates).
Arduino's extraordinary popularity has made it the focus of innovation for hardware and sofware hackers everywhere. The result is that they're wringing a suprising amount of performance out of a 16 MIPS chip:. Here are two recent advances:
