Today, Alexis found a pretty impressive component. The BNO055 from Bosch is a “9-axis orientation sensor” which is able to provide an absolute orientation ! Like an IMU, it integrates accelerometers, gyroscopes, and magnenometers, as sensors. A microcontroller running sensor fusion algorithms is also present in the chip. It communicates through an I2C or an UART bus. Moreover, it is already calibrated. It is just the perfect component for us. Here is a video of the sensor. We observe a short latency. It could come from the display. We’ll see when we’ll receive it.
I am very excited by this news. It will really help us in our project, AHRS seems very difficult implement.
