Latest Progress from the Folks at the GRASP Lab
Would love to see what flight control algorithm they're using on these things.
Great picture of the infrared lamps, at the end of the video:…Continue
After receiving much attention over the past few days, the aforementioned Eye3 Drone project on Kickstarter has been officially pulled on account of photoshop shenanigans and overall shadiness.
HobbyKing's done it again. Check out this deal: their mini-quad with four motors for $33.95! (Or $31.95 if you just let your browser sit open on that page for a few minutes).
All you need to add to make a RC quad (in…Continue
I have just finished the first revision of my full frame. The arms are designed to be very ridged in every bending moment. I added anchor points to the arms about half way out. This will allow me to attach stay wires that will also help keep the frame ridged. The hub is designed to break at bolted connection to the arms in the event of a hard crash. The hub has the fewest parts and would be easiest to replace. The arms can fold together for compact storage. The hole…Continue

A feature frequently requested is to add support to ArduPlane for using sonar to control the landing flare.The answer, unfortunately, is probably no. Take a look at this graph I obtained yesterday...
This has been on my to-do list for ages as I have never gotten around to getting some real world data to see if this would work. Finally got the real world…Continue
A 3x2 propeller, another tuning of the PID & azimuth, & a lot of camera flashes got it up to 9 minutes. Previously, it was a 3x3 propeller. The motor stayed just cool enough.…
It took me a while to get to this point, Build log (in dutch) but now i am almost there. Yes almost, I've got myself a very strange arming procedure. But enjoy the video first.
This week all necessary parts for the QRM quadcopter arrived, and we test fitted them on the aluminum prototype frame. Everything fitted perfect, and we finalized the designs so that the frame could be machined out of carbon fiber.…Continue
Wow, the fun I've had and the things I've learned along the way with this little project. But at long last, I'm happy to say that I've actually finished the build! This whole thing started as a way to relax and pass the time during the holidays. I was thinking at the time, that I'd actually be able to finish things a month ago and end my holiday break with something that was at…Continue
I have just finished the design and prototype phase of my open source quad frame. Its a 1.5mm G10 frame for 10"-12" props. I am in the process of designing a two axis gimbal for it, but to do this i need access to a faster prototyping process. I have entered the instructables shopbot contest and I really hope that i can win that as it will make prototyping so much easier. I've spent approximately 3 months on this design so id really appreciate it if when downloading the dxf…Continue
Sorry for the video quality, but the slr was tied up :)
Finally finished the universal IR camera shutter release device.
The requirements were:
1. Remotely trigger the camera to take 3 photos in a row using a switch on the transmitter.
2. A solution that doesnt involve a physical connection to the camera, as my…Continue
I have been working through the idea that in the future the functional equivalent of military UAV surveillance systems will be implemented by government agencies for domestic policing. I am interested in the software systems associated with networked surveillance platforms.The following is some fiction that I wrote to help me visualize the processes…Continue
hello friends, I have a new toy
It is a fiberglass telescoping tube with a length of 6 meters!…
Sebastian Thrun, most well know for the Google Car and his recent online AI class at Stanford, is branching out with a new startup focussing on online education.
He will be teaching a free 7-week class "Programming a Robotic Car" starting on February 20.
There's no direct link to the class, but …Continue
Here a video of a long duration LOITER (GPS position Hold) with my QRO quadcopter piloted by the ArduMega v2 board and the firmware ArduCopter v2.2 B4xp1 (with JLN mod). The flight is very stable and secure.…Continue
Please join me and other Bay Area UAV fans for a "drone hacking night" at the Ace Monster Toys hackerspace in Oakland. It will start at 7:00pm at the space at …Continue
An update on my project (please see my previous two posts).
This is a screencast of APM2 running in HIL mode with the X-plane RC plane in an 8kt wind over a simple course, takeoff, circuit including loiter, land, fully auto (radio not touched). In…Continue
