Hi, I repeated my previous experiments with rotations about the x - axis and the y - axis separately and received contradictory results from what I posted previously. The ONLY change is that I upgraded the firmware on the sensor to version 1.7.3. …

Thank you Matt. How then would I use the mbient sensor to ascertain Range Of Motion (ROM) in degrees of a joint we are testing, say for example the knee?

Please explain to me how you would convert sensor quaternions into Euler angles. I am using the following code: def quaternion_to_euler_angle_vectorized1(w, x, y, z): ysqr = y * y t0 = +2.0 * (w * x + y * z) t1 = +1.0 - 2.0 * (x *…

Using firmware version 1.7.3, I notice that when I COMPUTE Euler angles from quaternions, roll (about x-axis), pitch (about y-axis) and yaw (about z-axis) CORRESPOND with the Euler angles as reported by the sensor. Was this an update that was made …

Sorry, error in my last question, corrected above:
-
If the sensor is oriented with the x-axis pointing up (towards the sky) and I rotate the sensor about the z-axis (yaw), what should I expect to get when I convert the quaternions back to Euler angles? I do not see Euler yaw (z), I see Euler pitch (…

Have the pitch (x) and roll (y) been swapped in the latest sensor firmware (1.7.3)?

Would you be willing to share your code that you used to show the orientation of the sensor from quaternions?
