Interesting site

Hello everyone, I have just found this site and looked at a few of the pages. I have wanted to get into the small uav type aircraft so this site is just what I have been looking for. I have just purchased a Hobbico NexStar but have not yet made the first flight, except on the simulator. This is the gas powered version and is slightly larger the the ElectriStar being used here. I have looked at the huge open bay where the RC system is and I know there is a lot of room to install more stuff.…

Attempt at a 100,000 ft UAV flight

From the MAKE blog:

Here is a link to pictures of an attempt by a group of Calpoly engineers to have a UAV glider bring back pictures from 100,000 feet. After some sleepless nights and an overwhelming amount of work on hardware and software we launched a glider in California Valley. The…

3D Robotics
Update 6/17

Flew the Lego Autopilot UAV and the cellphone autopilot UAV (sans cellphone) on Sunday to test some new stabilization calibration. Again, if the definition of a successful test is useful data and no crashing, this was a success, but it was a little tense at times. Lessons from these flights:



1) The Lego autopilot suffered a mechanical malfunction. One of the gear linkages came off in midair, freezing the autopilot in the "on" position. This meant that I had to fight a hard-left rudder… Continue

GeoCrawler 4 (Predator airframe and AttoPilot autopilot)

Description: This UAV is not functionally very different from GeoCrawler 4, with its off-the-shelf Picopilot GPS-guided autopilot, but it's so much cooler! If you're going to build a UAV, why not make it look like a UAV? And… Continue

Armed forces now has 3,200 UAVs, most of them under 10 lbs

From Wired's Danger Room blog:

Raven_uav "The number of flying robots in the American armed forces' arsenal has gone up by nearly 1400% in four years, military documents show. A relatively-modest unmanned fleet of 217 machines has grown into a 3211-drone…

GeoCrawler 3 (BASIC Stamp autopilot)

Viking1

Description: This UAV is intended mostly as an education platform to teach you the basics of microprocessors, embedded system programming and autopilot design. It will fly, but it's not designed to be a real production UAV. That said, it demonstrates the…

GeoCrawler 1 (Lego Autopilot) Instructions



[NOTE: This post describes the original version of the Lego Mindstorms autopilot, which is a navigation-only (rudder and GPS) autopilot. Since then, we have created a full navigation-and-stabilization (aileron and elevator and GPS) autopilot. However, since it uses prototype hardware that is not yet commercially available, I'm not posting full building… Continue

3D Robotics
Update--6/11

  1. I've updated the GeoCrawler 2 (Lego UAV) instruction page. It now has a list of steps and parts necessary to complete the compass-sensor version of the UAV. The GPS version software is still in development. That should be ready later this summer.
  2. I've switched GeoCrawler 1 (Picopilot UAV) to a more appropriate airframe.…
