As you know, we've had a lot of trouble with the short range of our Pololu IR transceivers
that we use with our Blimp UAV
. They're rated at up to 20 feet, but we can't seem to get more than 10 feet (and usually more like 5) in real world conditions, with the usual amount of IR noise and the two transceivers not being on the same horizontal plane. I know that… Continue

Frustrated by difficulties in achieving adequate stability with my coaxial and quad flyers, and inspired by the efforts of Chris and Jordi with their BlimpBot project, I commenced yet another attempt to defeat gravity with a robotic entity.
This new project employs a relatively inexpensive 66-inch helium blimp from RC Guys
, modified for direct motor control using the H-bridge built into the radio board portion of the… Continue

I finally got my Wiring board form Sparkfun! Wiring
is a platform similar to the Arduino but using an AVR atmega128 chip. This chip is clocked at 16Mhz while the Arduino is clocked at 20Mhz. The advantage of the 128 is the increased RAM, ROM & Flash capacity over the Arduino. Both share the same development environment and code written for one can be made to run on the other. A '… Continue

I'll be the first to admit it: I had to relearn a lot of trig that I was last taught in 7th grade when I started work on autopilots. Now Freescale, who makes accelerometers, has come out with a really easy to understand primer

I went to the AUVSI (Association for Unmanned Vehicle Systems International) conference In Washington DC from Febraury 27-29. Each day focused on a different type of unmanned system. The first day was exclusively ground systems, the second day was maritime systems and the third day was air systems.
For the most part, the presentations were military related. One point that was repeated again and again during all three days was the need for integration and interoperability. The… Continue

Yesterday Jordi and his wife drove up with the BlimpBot to Monterey, where I was attending the TED conference
, so I could demo it. This was a pretty high-stakes demo, since not only would there be 2,000 of the most influential people in the technology, entertainment and design (TED) worlds watching, but… Continue

Finally we have the final version of the first prototype of ArduBlimp, wells know as the "Minimun Blimp".
* Hold altitude with PING))) sensor...
* Fly around the infrared beacon...
* Use Arduino Lilypad, for low power consumption ...
Some High… Continue

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

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

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

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.
Using a SMD Accipiter Badius as a basis,enlarge the airframe by 2.5 times.
Using a weedeater motor, centre… Continue

Some of you may have noticed that for quite a while SparkFun has been listing a "UAV Development Platform - ET312 + IMU

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
