The Christmas Gift

The sale plane that i was building is about 3/4 of the way done, and i had to stop (unexpected guests and no where left in the house to build it), but for Christmas i was givin a small 95% ready to fly park flyer. now its the 29.99 special from Harbor freight called the yellow bee. but its actually a fun little airplane to play with until i get my other one done and get a radio for it. i have already crashed my "yellow bee" on the first test flight i lost control and it landed in a neighbors… Continue

Building a UAV for photo mapping - Trial Balance





I have now finished all the sub-assemblies of my Cularis, so before sticking the fuselage together, I decided to do a trial balance to check on the COG. Here it is, poised on the wing

dimples. The airframe, with installed servos, but not motor, battery

etc. weighs 1.1kg including the two steel balls…

Which Multiplex powered glider makes the best UAV platform?

Like everyone else, we're huge fans of the Multiplex EasyStar, a cheap, sturdy and good-flying powered glider. It's a great aerial imaging platform (see our how-to… Continue

New WowWee indoor copter is "autonomous"

At CES WowWee introduced the semi-autonomous micro indoor "Bladestar" copter, which uses IR sensors to stay away from celings, walls and, they claim, people. More, including video, at Gizmodo. Hackable?



WowWee also… Continue

Blimp UAV project: spec'ing it out

As discussed in the white paper, the aim of the blimp UAV project is to build a prototype for an indoor aerial robotics contest. This will require contestants to design, build and program a blimp that can navigate a course inside a gym-sized space and potentially do… Continue

Blimp UAV project: The beginning

Aside from building this site, my two big UAV projects are taking the Lego Mindstorms UAV to the next level (it's mindblowing, although I can't talk about it yet!), and building a prototype blimp UAV as a platform for a potential indoor aerial robotics contest.



This particular blog series is going to be about the development of the second of… Continue

UAV Electronics Integration

For those of you who have not heard of this project, I am a member of the Missouri University of Science and Technology UAV Team (www.aessuav.org) and we are building a UAV to compete in the 2008 Australian UAV Outback Rescue Challenge. We are currently in the processes of integrating all of our electronics that will go into our UAV (you can find previous blog posts about our progress on our site). I'm not sure if our project would really fit… Continue

Reminder: keep your UAVs under four pounds

It looks like UAVs under 4lbs are going to be treated more lightly in the forthcoming FAA UAV regs. "Forthcoming" meaning 2010, of course ;-)

The DIY Drones Mission (aka The Five Rules)

"Because $10,000 $5,000 $1,000 is too much to pay for an autopilot, especially one that doesn't do exactly what you want."



An Unmanned Aerial Vehicle (UAV, colloquially known as a "drone") is…

Basic Stamp autopilot tutorial, part 3

SparkFun has quite a few GPS modules, but I prefer the EM406, because it uses the standard 5v power we're using on the dev board (as opposed to the EM408, which needs 3.3v) and has a handy red LED to show sat acquisition status (the 408 doesn't).



There are two difference between using the Parallax GPS module and a third-party… Continue

Our new site design--pretty cool, huh?

Just a quick note to call out Carl DeTorres, the Wired designer who did our new header and background graphics. (why didn't I have cool wallpaper like that when I was a kid?) We're still thinking about color choices and site architecture, so if you've got suggestions, please leave them in the… Continue

Amazing new robotic fly from Harvard: fly-sized, really flies!

Harvard professor Robert Wood has demoed a robotic fly, which is the first to be both actually fly-sized and have a higher power/weight density than an real fly. From this good article about the project:

Cool video on the Australian UAV contest (including high school contestants)

The folks behind the Australian Outback Challenge, an amateur UAV contest, have just posted a great video from their inaugural competition, held this September. It had two levels. The first, for high-school students, involved one team member controlling a R/C plane while another used onboard telemetry to guide the pilot over a target, on which they were supposed to drop a golf ball. The second, for university and above contestants, required a… Continue
