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

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.…

Lego Autopilot first flight

My kids and I actually had the first successful test flight of the sub-$1,000 UAV two weekends ago, but I haven't had time to edit the video properly until now. The good news is that a) it didn't crash, and b) it works. We tested stabilization, autonomous navigation (only using compass headings this time, although GPS is in the works), and the real-time video downlink. Everything worked well enough that we're able to see what we have to improve, which is the definition of a successful…

First test flight

May 13th, first test flight of both the Lego UAV and the stealth "minimum" UAV at Alameda Naval Air Station. Video coming soon.

'

Subsytems tested:



--Flight stabilization: Worked. a little rocking, but nothing too serious

--Autopilot: Sort of worked. Rudder throw needs to be increased. Heading change induced expected counter force by stabalization, which increased rocking. As a result the turning was very gradual. That needs to… Continue

GeoCrawler 4 (Picopilot off-the-shelf autopilot)

Hla114

Description: This UAV, which uses an off-the-shelf autopilot, is the reference platform against which we benchmark the more innovative (and cheaper) custom UAVs that are our main focus at DIY Drones.

The video system listed below, which streams realtime video via a 2.4 GhZ wireless…

Hacked E-mails Fuel Climate Change Skeptics

Hundreds of private e-mails and documents hacked from a computer server at a British university are causing a stir among global warming skeptics, who say they show that climate scientists conspired to overstate the case for a human influence on climate change.



The e-mails, attributed to prominent American and British climate researchers, include discussions of scientific data and whether it should be released, exchanges about how best to combat the arguments of skeptics, and casual… Continue

Agricultural research at Montana State

Dr. Charlie Rush and Montana State graduate student Ian Johnson have been using the 3DR Y6 for some foundational disease detection and prevention research. Their project aims use aerial imagery to detect wheat crop diseases. These pest-caused diseases can lead to poor water uptake by the diseased wheat, and ultimately wasted water and wasted money.  Here's the full…

Cheap Scratch-Built Drone from Scrap and Crap (FreePilot) - Part 0 [NEED YOUR HELP]



 

I want to share my journey of designing a drone in India, start to finish, hopefully for cheap and mainly built from recycled items to keep the costs down.

I started this project as a free-time project, but I would like to carry it on as a mainstream project with help from you…
