IMU - Orientation to vector to position

[Pixmusix]

Yeah! @Sally261693.
Great to have you on the forum.

That’s totally possible.
Check out this thread that’s super similar to yours.
Here I use an arduino library to extract a vector.

Obtaining orientation from an IMU

Have a look at this library by adafruit that interfaces between the arduino and the lsm6ds3trc You’ll also need some code to calculate the 3d distance travel between each loop. I’d recommend a crude linear algebra approach. /* UNTESTED CODE!!! THIS CODE IS INCOMPLETE AND FOR INSTRUCTIONAL PURPOSES ONLY */ struct GVec { float x; float y; float z; float dist(GVec v) { float dx = x - v.x; float dy = y - v.y; float dz = z - v.z; return (float) Math.sqrt(dx*dx + dy*dy +…

From there you want to finding the heading unit vector (i, j) to figure out which way is forward.
Then you call the angle of the z vector AGAINST that i+j vector.

Vectors

Are you using a microcontroller to read the IMU?
Have you programmed before?
