Interview: UNAV's Dave Perry on the PicoPilot autopilot

If you want an autopilot for less than $1,000 today you only have two choices: Do it Yourself or buy a PicoPilot (Dean Goedde's AttoPilot isn't out yet). The PicoPilot, which has been out since 2003, is small, light, and simple, and comes in varieties that range from simple one-axis rudder control to barometrically controlled elevator and/or throttle (prices… Continue

Lego GPS Autopilot code now less buggy!

For those of you interested in building a Lego Mindstorms UAV, two updates:



1) I've improved the RobotC code for the Bluetooth GPS version, in which I caught a lot of bugs. If you were having trouble with it before, download it again and see how it works.



2) At an event in April (can't say more than that), I'll be unveiling the next version of the… Continue

Well it has taken me about a month but I think I finally have a plan!

Well it has taken me about a month but I think I finally have a plan for a UAV.

Please excuse my childlike MS Paint style diagrams! This is what I would like it to be able to do. It is using in the BASIC… Continue

New Concept

Ok bear with me here because i have no drawings or diagrams. Basically this is a device designed [thought up] to transmit or receive or tranceive (im not sure how to spell it). Basically this will transmit information about your aircraft from speed to altitude to lat-long basically this is connected to a receiver attached to an OLED screen so you wear it on your wrist and get all of your information on your wrist instead of a ground station in a big van thats wasting gas. If it happens to be a… Continue

MAKING A UAV FOR WEATHER SPOTTING OUT OF JUNK

SPEC OF PROJECT



Build an airframe to be able to travel aprox 900 miles.

Use a ENT pnd as the controller and gps platform.

Comunicate with the UAV via cellphone modem to laptop.

Use Google Earth as the mapping and position indicator.

Photograph the area of interest storing info on board UAV to be downloaded when recovered.





AIRFRAME

Using a SMD Accipiter Badius as a basis,enlarge the airframe by 2.5 times.

Using a weedeater motor, centre… Continue

BS2p auto pilot under microsoft flight sim 2004

I simulated the bs2p under msfs last night . i programed a waypoint in marysville ,wa ,engaged auto around sea-tac airport, it took an east heading ,flew over the cascades into eastern washington then did a 180 flew to around mt rainer then headed east agian then i think my batteries died and it drifted… Continue

New autopilot/IMU board from SparkFun

Some of you may have noticed that for quite a while SparkFun has been listing a "UAV Development Platform - ET312 + IMU" that's always been out of stock. I backordered one out of curiosity last year, and pretty much forgot about it. Then, last week, SparkFun called and said… Continue

Minimum Blimp UAV bench testing

Jordi and I have been hard at work on the Minimum Blimp UAV and things are coming together nicely. Here are some videos:



First, a test of the Ping))) sensor that we're using for altitude hold. Don't you love the tray-table simulation platform? ;-) The Ping))) sensors are strapped to the far end of the… Continue

Demo of a failsafe board for the Basic Stamp autopilot

In an earlier post, I discussed the importance of having a redundant failsafe board so you can regain control in the advent (likelyhood!) of an autopilot failure. Basically, what that board does is sits in-between your autopilot, RC receiver and servos. You switch it… Continue

GPS simulation with Microsoft Flight Simulator 2004

We love FlightGear and all that it stands for, but the truth is that it's a bit complicated for beginners. For the rest of us, there's the old stand-by, Microsoft Flight simulator. There's a free plug-in for MS Flight Simulator 2004 called… Continue

Short Range I.R. Radar

Basically here is the site it is a short range inferred radar that could be used for a failsafe in case your uav gets close to the ground. However it is slightly bulky but that can be easily modified because it was made for parking cars. This includes a servo with an inferred transceiver or receiver and transmitter separate, i haven't really looked into it very far. If you are board and want to serf the web go to "… Continue

How college Blimp UAV contests work

The main existing US Blimp UAV competition is the Indoor Aerial Robot Competition (IARC) held every year since 2005 at Drexel University in Phladelphia.



The contest is designed mostly as an exercise in remote control, both human and computer. The blimps appear to be all RC, with wireless… Continue

Blimp UAV update: Minimum and Maximum versions

We've forked the Blimp UAV into two projects, a minimum and a maximum one. The maximum one is the one that's using the NorthStar "synthetic GPS" directional system and all sorts of other goodies to be a real indoor UAV, with full room sense and navigation… Continue

Some upgrades/changes to the site

As some of you know, this site is based on the Ning platform, and they've just rolled out some changes. Relevent parts for us include:



--Mass Uploader for Photos, Videos, and Music/Podcasts

You'll now be able to upload up to 100 photos, 30 videos or 100 songs/podcasts in one fell swoop. That's not to say that adding all of this stuff won't take forever, but go grab a snack or five and you'll be all set.

Frankly, this is a… Continue

added duct to coaxial rotor



Big improvement in stability with the addition of a simple duct made from a sheet of 2.5mm RCF (extruded polystyrene) foam from rcfoam.com. The RCF is similar to depron that was recommended by another forum member, but somewhat more flexible and higher density. I was able to bend the RCF sheet to a 12-inch diameter, while a similar thickness depron sheet broke when bending.





There is some yaw rotation at the beginning of the clip, but you can… Continue

Dealing with different GPS versions

Another advantage of GPS simulation: you get to discover horrible glitches in the matrix, such as the inconvenient fact that GPS comes in different dialects, each of which requires different parsing. I found this out when my GPS parser was working with the simulator, but not the real EM406. The problem turned out to be that the simulator outputs GPS time as… Continue

Why you MUST simulate before flying

I've had a couple people ask why there's such an emphasis here on GPS simulation. The simple answer is "Because we don't want to lose our UAVs!" With regular robots, when they've got bugs or software crashes, you just pick them up and fix the problem. With UAVs, they're likely to fly away forever or end up in a pile of pieces. They're more like satellites or Mars rovers than battlebots--you can't fix them from the ground, and when they go wrong in the air, it can be catastrophic.



One… Continue
