Mikroquad

Wow, I can't believe I missed this one. Someone has been working (HARD) on an Arduino based quad.

Their source was put up on the 21st of December

Looks like a great start. I need to get my planes finished so that I can build one of these too!

Review: World's first toy autopilot

WowWee's BladeStar indoor flying machine is advertised as the first toy with an autopilot. From its description: "The exclusive Autopilot Mode with sensor-based navigation enables it to glide… Continue

VicaCopter 3.0 4 U

2 months after VicaCopter 2.0, it's VicaCopter 3.0. The autopilot has been moved to quad rotors. All control is done by VicaCopter. Just get 4 motors, 4 ESC's, 4 propellers, & fly. The quad rotor is the cheapest & easiest route to the air.



A UAV programming language has replaced the table of waypoints to enable more complicated maneuvers. Automated takeoffs & landings, curved paths, pirouettes, turning towards a point are supported.

ArduPilot code now in beta!

Jordi's finished the first beta of ArduPilot, in anticipation of the board's commercial release. Changes and improvements include:



  • The code is now hosted in a proper code repository (Google Code) for version control and to allow others to contribute to the project. You can find it here.
  • RTL (return to launch) and waypoint modes are user selectable
  • Waypoints…

Test flying an EasyStar with EasyGlider wings

After testing the new 4-channel EasyGlider Pro and finding it a great flier but without as much internal space as our beloved 3-channel EasyStar, people suggested I just modify some EasyGlider wings (which have ailerons) and use them on the EasyStar.



So I did that. It was a pretty easy mod--you just have to carve off a little foam from the Easy Glider wings and thread a aileron… Continue

My Initial UAV Project Proposal

Hello all,



This is my debut to the site and I will try to continue to post throughout the development of my project. I am a senior in Computer Engineering and for my senior design I have chosen to make a fully autonomous aircraft. I have no experience in flying rc airplanes but I just have extreme interest in airplanes. I have three other team mates (1 computer engineer, and 2 electrical engineers). For the last month, I have been researching rc aircrafts and devices that I will need… Continue

A Loaded Question (I think)

I am curious to know how members of this community got to where you are with regard to knowledge of controllers and the associated programming. I have been reading this site for weeks, have gone through much of the Paparazzi site and am getting overwhelmed with just where to begin to learn; or more precisely, where to go from here. It's all a little haphazard and disjointed. I even downloaded the Basic Stamp training materials and worked through the exercises (mentally, at least).



I… Continue

Maiden flight of "The Kodel": autopilot-to-be

Today my autopilot hardware took the sky for the first time. Although this maiden flight was successful, its only a first step.





The primary goal of the test was to see if the autopilot failsafe mechanisms operated fine:

- no lockup on division by zero

- instant regain of control after brown-out causing reboot

- no lock on uncaught interrupts

- handover to servo failsafe positions on RC reception lost

- instant… Continue

SkySailor - 27 hours autonomous flight

I came across a nice project for those interested using some solar power for their UAV. It appears that this relatively small plane was able to fly autonomously for more than 27 hours over 874 km (in big circle, but still...).

Wondering about adding altitude and attitude sensors

With some simple sensors we could detect the pitch and altitude to make better decisions about altitude changes and what to do with them. I'm thinking 2 sensors from sparkfun would do the trick.

Original DIY Drones UAV projects

These are projects from 2007 and early 2008 that were a lot of fun to do and are still worth checking out for UAV ideas. There is also a PDF/poster that shows how they compare to military and commercial drones.

Reading PWM from a receiver

Hey all.



I know this subject has been covered in many ways, but I am hoping that someone can assist me. I hope someone can have the patience to answer a few of my VERY NEWB questions.



What I am trying to do is to send PWM to an arduino on an air vehicle which will then send the appropriate servo controls. Simple enough some may say, but I am in a bind since I just cannot get my head wrapped around this and frankly, I think my research has gotten me confused.

Interesting 900MHz radio



Take a look at http://www.avalanwireless.com/product_list.htm. Click on OEM Radio Modules and check out the AW900mSPI.



The AW900m is a 900MHz digital radio with lots of range and throughput - 1.54Mbps radio channel with 900-1100kbps delivered. SPI/UART version will retail for $129 per card. These look really good - I should have a couple of modules shortly and will report on performance. The UART… Continue
