Trivisio Colibri - Inertial Motion Tracker
The Colibri is an universal 3DOF Inertial Measurement Unit (IMU) with very low power consumption, USB interface and both machine and human friendly interfaces.
It carries 3-axis state-of-art sensors to measure acceleration, angular rate and magnetic field.
Built-in temperature sensor helps to eliminate temperature influences on sensors.
Colibri can output both raw sensor data and calibrated floating-point data.
You may enable/disable data from any sensor and change frequency from 10 to more than 100 Hz.
The supplied API for Windows and Linux implements extended Kalman filter for orientation tracking.
Using it you will simply get orientation data in Euler angles or quaternion form.
Colibri comes in a robust, high-precision aluminum case.
