Resumo(s)
This work presents relevant theoretical and practical
aspects towards the design of a quaternion-based real-time
Attitude and Heading Reference System (AHRS). The motion
sensor used in this work is the TDK InvenSense MPU-9250
9-degree (gyro + accelerometer + compass) Microelectromechan ical system. Results show that the AHRS developed device is
“gimbal lock” immune, given that the 3D rotations are per formed in quaternions. The tiny electronic device allows real-time transmission of the 3D orientation and can be used as an
AHRS solution for medical, sports science, rehabilitation and
assistive technology. The contribution of this paper is a theoretical
methodology and a practical implementation of an AHRS device
for Biomedical applications.
