Hey all,
I'm finishing up a new quadrotor/octocopter autopilot design. I just got my second revision board populated and tested. I was excited enough about it that I thought I'd share it... :-D
Some of the features of the autopilot are listed below:
Read more…There has been an ongoing discussion/debate about whether accelerometers are actually useful for attitude estimation on flying rotorcraft (quadrotors, in particular). The simple, one sentence answer is "yes, they are."
However, the accelerometer me
Read more…Hey everyone. I recently finished a new AHRS (see the picture below). The firmware is open-source, and I thought it might be interesting to you guys. The firmware supports EKF-based Euler Angle and Quaternion estimation, depending on what you want
Read more…Hey everyone. I'm just finishing up a new AHRS design (see picture below). The sensors it uses are almost exactly equivalent to the Razor from Sparkfun, but I added a nice 3.3V regulator and a STM32 processor running at 72 Mhz. The faster processo
Read more…Hi all,I am finishing up a 6-DOF design using ST's new family of rate gyros and the ADXL335 from Analog Devices. (See http://www.diydrones.com/forum/topics/best-setup-and-pinout-for-6dof for some older posts on the topic).The IMU uses the STM32 micro
Read more…Hi all,I am designing a small 6-DOF IMU with digital outputs that uses the newest MEMs devices on the market (some of which haven't been released yet) to keep the footprint small and the cost low. I'm hoping to make a bunch of them and sell them at l
