Razor AHRS Visit project website

An open-source real-time orientation tracker, head-tracker, AHRS (Attitude and Heading Reference System) or what ever you want to call it.

It uses the Arduino-compatible “9DOF Razor IMU” board by SparkFun, which contains a 3-axis gyroscope/accelerometer/magnetometer and a microcontroller to do the sensor fusion. Alternatively the “9DOF Sensor Stick” can be used in combination with an Arduino board. Wireless tracking is possible when using a bluetooth modem, e.g. the “Bluetooth Mate”.

Have a look at the tutorial in the Github wiki for detailed info. The code at Github contains:

  • the Firmware and a Processing test sketch (Mac OSX, Linux, Windows).
  • a C++ library and a test program to read the Razor on Mac OSX, Unix and Linux (sorry, no Windows).
  • an Android Java library and a test App to read the Razor on Android 2.0+ devices.
