Hello all,I'm thinking of using the following for an autopilot:Arduino Mega connected to:9 Degrees of Freedom - Razor IMU - AHRS compatibleSerial Servo Controller -> connected to at least 3 micro…Continue
We've recently made the move from the old clunky DCM implementation to a new Quaternion approach, and it seems to perform better, or at least the code is much smaller and takes almost no time at all to execute on our 72MHz 32-bit flight controller. I'll be writing an article on the Quaternion method as part of our series on Engineering Insights.
We've also added MAVLink support, and full integration with QGroundControl GCS. This helps greatly with debugging, and of course enables…Continue
Video of ROFL Tuning Session with spectacular crash when we deliberately detune one of the PID values! No quadcopters harmed (much) in the making of this video. Video of stable flight below.
By the way, the ROFL quadcopter kit is still on sale on my website:…Continue
Seraphim is our sensor board for the quadcopter, it includes accelerometer, gyroscope, magnetometer, barometer, GPS and micro-SD card slot. With the exception of the GPS unit, all of these components are a complete pain in the backside to solder properly, and there are some consequences of not…Continue
Here you can see the little guy we have just begun to use and will be releasing for sale in early October. The black Forebrain board is what was running the autopilot code in ROFL up till now, 72MHz ARM Cortex-M3 microcontroller, measures 66mm*23mm. The longer Hivebrain board is what we will switch to and will…Continue
