Virginia Tech UAV

This is a nice writeup on a UAV built by student group at Virginia Tech. Not cheap; but a nice setup.

Lego GPS autopilot code now in beta!

Big news: we've finally got a version of the Lego UAV that's based on GPS! The previous versions used a compass sensor as a proof of concept, but we've now upgraded it to use a third-party GPS receiver, connecting to the Mindstorms NXT brick by Bluetooth. This allows us to employ… Continue

Cellphone UAV code now in beta, available here

In my focus on the Lego UAV, I forgot to mention that I've also uploaded the Visual Basic source code for our cellphone autopilot. It's in pretty good shape, and just needs a little more tweaking for reliable airbone use. If you're comfortable with Visual Studio and Windows…

Impressive new quadrotor UAV with camera board

You may have missed it in the discussion threads at left, but Howard Gordon has been doing some terrific work combining his robot and camera control boards with UAV platforms. The latest uses the quadcopter platform that the X-UFO/X3D guys in Germany developed. Check out his full post…

UAV causes media stir.

Go here first.

Is more being made of this than is necessary?? I wonder why the reporters spin did not point towards the environmental benefit of UAV's less gas than the helicopter. The newscopter that was chasing, is that not invading the privacy of some police officers on a private farm??…

A budget for a high-end amateur UAV

An amateur UAV maker in Los Angeles built a UAV designed to fly 21 miles, from Long Beach to Catalina Island and back. It was notable especially for having the motor moved to a pylon above the wing and a pan-tilt gimbal camera put in the nose instead (see picture). This thread about it on RC…

Use an open-source flight simulator to test your UAVs

Tom Pycke, who is one of the more sophisticated UAV hobbyists, has a good post showing how to use the open-source Flight Gear simulator program to test your autopilot code.

He begins:

"A lot of people think they need great electronics skills, a lot of time, and embedded programming skills to experiment with Kalman filtering of IMU-data. Think again! The key to all your success stories is…

MAKE magazine on DIY blimp UAVs

The cover of MAKE magazine this month is a how-to on "blubberbots", which are small indoor blimp UAVs (story only for subscribers for the moment--subscribe! It's worth it). You can buy a kit from the MAKE store for $99 that will allow…

Antarctic mini-UAVs--will they come back?!?

These scientists describe their UAV project at the South Pole. Sound familiar?

"Flying a mission is always a little scary. Tom, the project engineer and pilot, stands by with his remote control and flies it a little until a stable flight is acheived, then…

The best programming language for Lego Mindstorms, hands down

Play around with Lego Mindstorms NXT enough and at some point you'll inevitably get frustrated with NXT-G, its graphical programming language of "blocks" that you drag around and connect with "wires". It's great for teaching kids the basics, but once they embark on anything remotely ambitious they're bound to run into trouble. Whether it's the crazy sprawl of blocks over the work area (even a simple loop can require screens of slow horizontal scrolling), the lack of floating point…

Interesting looking airframe

Whilst perusing RC groups I came across this challenger review, looks just the job for aerial photos, combining size (lifting ability) and a rear mounted engine. I'm sure it would'nt take too much effort to make this a tail dragger. No prop in forward facing shots.

Whilst your there its worth having a look at… Continue

Watch the DARPA Urban Challenge Live--NOW!

If you ask me, this is better than NASCAR. The DARPA Urban Challenge (robot cars race though a town) is being webcast live now.

Very well done live video is here, with color commentators, helicopter views and tons of team cams. Go…

Tring to get started

So i found this page after i watched the DIY UAV segment on wired the other day, and it has been something that i have been interesting in trying to do ever since i saw the preditor and the global hawk. But i just didnt know where to start, and the ideas that i had would have ended up costing thousand of dollars. so im really happy to find a group of people interested in doing the same thing.

so enogh about that. i was looking around the interenet today tring to find suitable aircraft… Continue

And on looking at the E6B

It would seem that being +30 at 4000' means something, which of course I already knew, but just what is the drop in performance on a 50 odd inch wing trainer??

What magic program or website could tell me that to lift lets say an extra 1KG of equipment at a density altitude of 7000' the aircraft would need to be X wingspan with Y power up front??

There must be…

Back home

Settled back in South Africa after the glorious world cup rugby victory!! A storm is brewing outside so can't stay long!

I have been itching to get a shot of animals to start the process of getting software to spot them for me (grown ups will work that out)

It also crossed my mind whilst flying down to South Africa that a Zagi or some such flying wing would be a very robust platform to play with. Having never flown a powered flying wing I made up a balsa box for engine and…

Back in the air - for about 10 seconds

The flight

My new parts arrived on Friday. Included in the order was a new RC plane (Firebird Phantom) as well - it turned out that it was cheaper to add the complete model to the order rather than ordering each of the parts separately. So, on Saturday morning, I took my new bird out for another spin.

The winds were much closer to ideal this time, and I imagine they were well within the tolerance of the UAV to maintain control - given a reasonably competent… Continue
