Great work on uav ground control stations

Hi all,



I was wandering around and guess what I found, an M.Sc. Thesis by Philip S. Anderson about the development of a UAV ground control station.

I haven't read it yet but it seens to be a really nice reference. He uses LabVIEW which by what I have seen is a very popular software among us(uhhh but I still a newbie).



What I think is a nice point of his project is that he actually built the system and put it on a van, so we can have a taste of what the military guys… Continue

Surprise! ArduPilot can do stabilization, too

We've been describing ArduPilot as a navigation-only autopilot and saying that it needs the FMA Co-Pilot to provide stabilization. But that's actually not true--we just hadn't written the stabilization code yet. ArduPilot is powerful enough to handle both functions,… Continue

Increasing GPS device (EM 406a) baudrate

Default baudrate of EM406a GPS device is 4800 baud. Then this baud rate dictates entire communication of serial port on ArduPilot - also those for Serial OUT (telemetry).



Here's simple way how to permanently increase baud rate of EM 406. Once done, the device will remember the baudrate, and you can increase serial speed in ArduPilot code.



1) Temporarily connect your GPS directly to FTDI… Continue

Posting

Posts are much easier to read if the poster uses capital letters where required AND correct punctuation!! Text type posts are not much use either, as a number of people do not bother to use a telephone for texts

UAV v2 development board is back in stock

The UAV development board is back in stock at SparkFun.



SparkFun also plans to eventually carry 12" cables for the GPS connection, which could be used for the UAV development board, as well as for Chris Anderson's ArduPilot. Sparkfun also plans to eventually carry 12" servo cables for connecting from the board to the RC… Continue

ArduPilot: How to re-flash Attiny45





This is a quick video tutorial to explain how to re-flash the attiny45 in ardupilot boards. You can also tweak the attiny code if you wish...



But first you need to fallow this steps:



1.-Buy an AVRISP MKII programmer, you can buy one in… Continue

Boeing’s Truck Mounted Laser Weapon Destroys Unmanned Aerial Vehicles

Watch out UAV builders or Boeing just might shoot you down with a giant freakin' laser beam! Directed energy weapons are still in their infancy, really, but it's only a matter of time. Today Boeing reported that they've successfully… Continue

Update on MUX issue with first batch of ArduPilot boards

The Sparkfun guys and we diagnosed the issue today. It was our fault--we had a version control problem with the Attiny code we sent them, and the bad news is that appears to have affected a total of 60-80 boards. For those of you affected, our apologies--we'll make this right. Here are your options:



1) The fastest way, if you have an AVR programmer, is just to reflash the chip with the updated code (hex file is… Continue

supersimple esc's and quadro-update

a little info i couldnt find anywhere else. while programming my quadrocopter, i somehow messed up the throttle start and end-points of one of the esc's. the motor started only when the throttle was already in the middle. after some googling and experimenting, i found out how to reprogramm the endpoints. this will probably work with other esc's too.



here's the exact procedure:



- connect esc to receiver and motor, do NOT connect battery

- on the (turned on) remote move… Continue

Simulating flight with ArduPilot

This is the first post in what I hope will be a mini-series on doing hardware-in-the-loop simulations with ArduPilot. A simulation is something you do to test your autopilot on the ground, where you won't get in trouble. It's an absolutely necessary thing when you're… Continue

quadrocopter

a few weeks ago i decided to build a quadrocopter. this would be a real challange but still inside the capabilities of the pcb i made. i actually designed it with plane-uavs in mind. but there's no reason it wont be able to controll a quadrotor.



here's the finished board connected… Continue

Getting started

Okay, I just bought my freeduino and a ADXL330(Wiimote 3-Axis Accelerometer module). I bought everything at seedstudio which cost me USD $45, a bargain, since here in Brazil just the freeduino would cost me slight less than the double.



When these two little babies arrive I will start myself in arduino programming and DIY stuff, since I started my computer science course I felt in love with this kind of stuff. I started reading in a daily basis things about PICs, eletronics,… Continue

Questions about piloting my Hawkeye RC with the ArduPilot

An old friend developed a nice Rogallo winged RC plane which he calls the Hawkeye. If interested, you can read about it at his site- http://electricflights.com/hawkeyemainpage.html



I test flew the Hawkeye last summer into the fall, until the rains returned to the northwest. It is very portable, easy to fly and designed to carry a camera. Shot lots of video and then realized that I want an autopilot to increase my odds of getting the shots I'm after. I'm game to try an ArduPilot, as… Continue
