Hi all, the ArduIMU+ V2 is sold out at the DIYdrones shop.The ArduIMU+ V2 has been discontinued without replacement at Sparkfun.The Ultimate IMU has been discontinued at Sparkfun.I think there was a…Continue
"The good old chinese south pointing chariot. Believe it or not most automotove dr systems now use that exact concept.
The wheel abs sensors on each wheel are used to differentiate a change of coure as each wheel will give a different reading
"The difficulty is the fusion of sensors. It's easy to make a navigation system with GPS telling you where you are, but the moment you start judging your position based upon other sensors, you start accumulating error. Allow me to…"
"A good new IMU is the Mongoose by http://store.ckdevices.com for 115 $US incl. shipping.
In addition to ADXL345 triple axis accelerometer, ITG-3200 triple axis gyroscope, HMC5883L triple axis magnetometer it has a BMP085 barometric…"
"I'm attempting to use the Sparkfun 9DOF AHRS in a real aircraft using the sf9domahrs code running on the IMU. With the AHRS taped to the top of the instrument panel, I am getting inaccurate pitch and roll data however everything works…"
I find myself in a position of being down to 1 ArduIMU and I would like to continue using the legacy Ardupilot. Thanks for the update as to available IMU's. The Mongoose looks like an alternative."
seems you are not even sure if is this going to be a AHRS or just a breakout board for a couple of sensors?
If I were you, I would do some research, then compare features of existing and upcoming IMUs, and then think about what…"
"I think the may difference is that the ArduIMU+ has a processor and runs a DCM filter to process it's sensors raw data.
While your Sparkfun 9DOF Sensor stick is a breakout board for three sensors only. No processing of the raw sensor data at…"
sounds easy to do.
Should it really be that simple to achieve?
My initial idea was to edit the AHRS code to read the data from the GPS, then add it to the IMU data, and then output it as it's done with the IMU data. Way more…"
"The GPS model you are planning to use may have an impact on the most suitable connection in regards to direct compatibility with the existing parsers available in the libraries. In order to use gps units that require initialization,
"Sure you can connect your GPS to it. Razor board have 1 uart port so to connect GPS you need to piggyback on it. Just connect your GND/TX from GPS to Razors GND and RX pins. Make sure that all serials are on same speed and voila, gps data starts to…"
