JC commented on Sys-Ak's blog post Crash 4 Sure: integrated Autopilot & OSD
"I really like the idea of autopilot+ODS in one system, any updates on the single board."

JC replied to Chris Anderson's discussion Discussion forum for UAVDevBoard, Sparkfun's 3-axis IMU-based autopilot board
"Will there be a UAVDevBoard 3? It seems the next version of ArduPilot is in the works, just wondering if the next UAVDevBoard is in the pipeline. If its not too late I would like to see one with flay gyros, and more R/C inputs and ouputs. Keep up…"

JC replied to Frank's discussion Ublox GS407
"I got a GS407 from sparkfun last month that was bad. It would not get a GPS fix indoors or outdoors. They replaced it with this GPS which is nearly identical, (the GS407 was out of stock). I hooked it up and got a GPS fix in less than a minute."

JC commented on Tim Trueman's blog post Want to test code with the simulator X-Plane?
"Tim, What variables are you using for accelerations from X Plane. From the input/output menu I see the angular rates but not the accels."

JC commented on Ryan Beall's blog post IMU nose Dive problem/solution
"Hi Greg Thats a good point, up elevator can also increase the rate of turn in an aerobatic plane. Its clear now that turn rate is highly dependant on the airframe. When flying an EasyStar the turn is controlled by the rudder (as apposed to…"

Project PropFIT

Posted on May 13, 2009 at 11:30am 7 Comments

Propeller Flying Inertial Testbed



Goal:

To develop and refine software that will read sensor values and perform the necessary calculations to produce a stable and accurate IMU (inertial measurement unit).



Performance:

The quality of the code will be evaluated on how well a simulated horizon aligns with the actual horizon. Using the Propellers video drivers, an artificial horizon will be displayed over a real world view to see how well they… Continue

Introducing the "OughtToPilot"



It seems the parallel processing ability of the prop makes it a top candidate for autopilot brains. This project was entered in the Parallax Design Contest and won second place!! The designer opted for a fuzzy-logic algorithm over a kalman filter for the IMU.





The OughtToPilot employs a… Continue
