Our next ArduPilot: the dual-core ArduPilot Pro!

[NOTE/UPDATE: All the below, from long ago, has been superseded by events. Basic ArduPilot proved capable of every this described here, so we cancelled this version of the product. Thinking about what the next version of ArduPilot could be can be found…

The problem with neural networks

This, from the always interesting Jack Crossfire blog, is the smartest observation on neural networks and genetic algorithms I've seen in ages. Excerpt:



"In our last experience with neural network feedback, the feedback always headed towards 0. That one used straight back propagation to predict cyclic from attitude change. That fiasco has cursed all future investments in the radically different genetic approach. The… Continue

Microsoft Virtual Earth now accepting DIY aerial imagery

Cool news from Microsoft: its Google Earth competitor, Virtual Earth, is now accepting user-generated aerial imagery. Unlike Google Earth, where your own data can only be superimposed on the "real" Google Earth data, and people will only see it if they… Continue

BlimpDuino home page



BlimpDuino is a very low cost open source autonomous blimp. It consists of an Arduino-based blimp controller board with on-board infrared and ultrasonic sensors and an interface for an optional RC mode, a simple gondola with two vectoring (tilting) differential…

ArduPilot Pro home page



[UPDATE Jan, 2009: The description below is our original conception of ArduPilot Pro. However, we were able to achieve all of these features with the basic ArduPilot, so we are now reconsidering what additional features to add to a future dual-core… Continue

Is GPS good enough for altitude hold?

In our quest to create the simplest and cheapest autopilot available, we're debating whether we need a barometric pressure sensor or can do reasonable altitude control with GPS alone. The old answer to this was the GPS alone wouldn't work--not only were errors of as… Continue

Review: new Arduino Nano board

Gravitech has now released a new Arduino board, the Nano ($49.99), which I think is the best one yet. I just got one, and have had a chance to compare it with the two other breadboardable Arduino options: the… Continue

How can we make IR beacons with unique IDs for Blimpduino?

Jordi and I are slightly stuck at the last part of our Blimpduino project. We've got the blimp itself all sorted, from electronics to mechanical assembly, and are ready to move into mass production on that. We intend to… Continue

ArduPilot: New Thermopile Boards!

Those of you following along with the ArduPilot development probably suspected that we weren't going to stick with leaving the stabilization function to the off-the-shelf FMA Co-Pilot for… Continue

New version of FMA Co-Pilot system coming

FMA just announced that a new version of their FS8 flight stabilization system (this is the thermopile-based Co-Pilot integrated into a RC receiver) is coming in the fall. No details on what will be different about the new version.



In the meantime, you can buy the old version (FS8CPI) while supplies last for $149.95. Call the FMA Sales line at 800-343-2934 (phone orders only). Picture of the old one… Continue

DIY Drones in the San Diego Union Tribune

A big story today in San Diego's newspaper about DIY Drones at the AUVSI conference. Excerpt follows:



"'Do-it-yourself drones' create buzz at S.D. convention



The unmanned Predator aircraft developed in San Diego during the mid-1990s has become a workhorse surveillance plane… Continue

RoboGames this weekend in San Francisco

This weekend RoboGames returns to the Bay Area. It describes itself this way:



"RoboGames is the world's largest open robot competition (even the Guinness Book of World Records says so!) We invite the best minds from around the world to compete in over 70 different events. Combat robots, walking humanoids, soccer bots, sumo bots, and even androids that do kung-fu. Some robots are autonomous, some are remote controlled - but they're all…

Five things I learned at AUVSI today

Wandering the amazing show floor at AUVSI in San Diego and talking to engineers there today with Jordi (shown), I learned a ton. Here are five things that maybe everyone else in the world knew, but I didn't:



1) "Primary" (non-rechargeable) batteries have twice the energy density of… Continue

A simple demo of how to read RC signals and drive servos with Arduino

Most autopilots have the ability to read signals from a RC receiver and drive servos. For instance, in the case of ArduPilot, we read the current throttle setting when the autopilot is engaged (so we can maintain that setting, although we'll later nudge it up and down to maintain altitude) and we drive the rudder servo and ESC. In the case of BlimpDuino in RC mode, we read the throttle and left/right commands from the RC receiver and translate them into commands to the motor drivers (the… Continue
