Missouri S&T UAV Team - Autopilot Tuning

On Saturday (April 5th) we flew the airplane for the first time with the autopilot since it got the new wing. But before we went out to the RC airfield we had to physically install the autopilot in the fuselage, which went well. We then performed all of the flights necessary to tune the autopilot in HIL (Hardware In the Loop) simulation mode.

Using HIL simulation allowed us to all to get a better of idea… Continue

Motor Glider UAV project

Hi all,

this is my first blog and I wanted to share that experience with you as most of my projects are about UAV and robotics.

First of all I got to thank the whole "DIYDrones" community that gave me a lot of informations and ideas in the past. And continues but... now I think it's my time to share my findings while developing my "ideas".

I usually work with the Arduino open platform but lately I've been working with… Continue

"affordable motion sensors may be at hand";jsessionid=GW53B4ZAN3QNAQSNDLSCKHA?articleID=207001827

So for UAV booms to become the dot com booms of the future, sensors need to cost under $1. Basically another year, another wave of startups, but no affordable motion sensors. Interestingly, this year they're not making the mistake of attacking gyros like Invensense did. They're focusing on accelerometers, not saying they're accelerometers, and selling the application rather… Continue

Taking Lego Mindstorms from toy to serious UAV platform

[UPDATE: after legal advice from LEGO, LatteBox has now changed its case design to remove the LEGO Technics holes, which you can see in these pictures. The new case is shown at the bottom of this post.]

What got me into this whole UAV thing a couple years ago was the crazy idea that I could combine my love of LEGO… Continue

Hi res daylight

Had enough daylight to get 1/400 ISO 80 out of the A560. It definitely does a better job with those 7 million pixels. 1/400 is probably just below the minimum shutter speed. In dead calm air, the camera was much more stable. With the current yaw program & the instability of 1Hz GPS, only had enough battery power for a 270' turn on… Continue

Project - RC Helicopter Stabilization with Arduino

This is my current Project-Plan:

Stabilize nick and roll of my Walkera Dragonfly DF36 with Arduino and provide an easy interface to the RC servo output.

(read acceleration data from a Wii Nunchuck and pulse servos to keep horizontal position)

First steps:- Hardware setup

- Create a starting sketch and develop it based on libraries and functions.

Thanks to everybody who is developing nice stuff… Continue

New Wing for Missouri S&T UAV Team

Sorry about the lack of updates, we will be updating more frequently now. The first update being that we completed the new wing and completed the first flight with the new wing and it performed very well even in windy conditions. Unfortunately there are no pictures of the actual flight but here are some pictures of the new wing on the airplane. This new wing is significantly stronger allowing us to carry our large payload, it also has less drag… Continue

Australian UAV contest announces its second year

The Australian Research Centre for Aerospace Automation has announced the second year of its amateur UAV contest, called the Outback Challenge, which will be held on the 23rd-24th September 2008, in Kingaroy, Queensland. There are three categories:

1) A remote operation challenge (fly by video downlink only) that's only open the Australian High School students

2) A autonomous UAV target spotting and package delivery… Continue

Daylight timelapse from autonomous hover

Got some timelapse of a hillside in wind. Wanted to face away from the sun this time but there was nothing to see. Note the sun reflecting off water on the hillside. These were 3k images.

a few ideas gleaned from the microblimp design

Along with a couple of Tri-Turbofan toy blimps, one of the purchases for my early blimp experiments was a Plantraco MicroBlimp, which is the company's current offering. After ordering, I found out that it was too small to carry any useful payload, so I left it in the box until deciding to take a closer look yesterday.

Plantraco seems to specialize in really small radio controlled aircraft. They tend to be somewhat expensive, but… Continue

PCB fabbing advice

For those of you getting into creating your own PCBs, here's some quick advice:

We use the CADSoft Eagle software (free version can handle up to two PCB layers). It's powerful but pretty hard to learn. For easier to use (albeit more limited) software, you might try… Continue

New double-sided BlimpBot board!

Our progress towards a $79 UAV mod kit for toy RC blimps is going well. We've now got a much better, two-sided PCB board that we're having fabbed. It's smaller, has more features and now integrates the IR sensors on the same board (Eagle schematic here; mask files… Continue

Interview: Martin Müller and the Paparazzi Project (now less DIY!)

We've been following the Paparazzi autopilot project with interest for several years. It's a European open source technology initiative that has created both thermopile (infrared sensor) and gyro-based autopilot hardware, along with quite sophisticated software to run it. But the problem to date is… Continue

Minimum Blimp V2 PCB files, code

This is just a quick update for those following along with the Minimum Blimp UAV project. We've modded a toy RC blimp and created our own Arduino clone PCB (complete with motor controllers and ports). Here are the PCB files and source code:

Nothing impressive, just my first aerial video.

This is my first aerial video taken with The World Models Super Frontier Senior 46. It's quite a large trainer plane with 2040mm wing span and a lot of dihedral. The fuselage also has a lot of room for my equipments.

The video is taken with the Canon PowerShot A430 digital camera attached to the bottom of the fuselage.

Currently, there is no autopilot system in… Continue

diydrones vs rcgroups vs runryder

Rcgroups & runryder definitely seemed to dry up after diydrones appeared. They're now more focused on promoting businesses while diydrones has attracted the hobbyists, but Ning really needs more organization than the Latest Activity list. Here's a robotic copter update.

Had to point into the wind for more stability. That's also where the sun is.…

Where are the "add blog post" and "add forum discussion" links?!

Last night Ning, our social network hosting platform, pushed out a few new features and in the process changed our look and feel a bit. Among those changes: the "Add a blog post" link at the bottom of the blog listings and "Add a discussion" link at the bottom of the forum listings are gone. So now how do you do those things?

Answer: use the tabs above. You add a discussion topic on the "Forum" tab and… Continue
