I want to Assess where someone’s ankle is relative to their hip. I have an IMU on the thigh and leg/shin (capturing orientation) and know the lengths of these. I want to know the distance down, across and forward between the hip and ankle. Is there code already suited for this application?
I have an IMU on the persons lower back and want the direction of forward/back and side/side to be relative to this IMU i.e the way the persons facing, defines what is forward.
Are you able to record the data in the experimental phase for later analysis?
Getting the Arduino nano to record the data onto an SD card would be easy. Then you can figure out all the vector stuff in a higher level language with more visual tools like julia.
Would that work for your use case?
Not sure I’m afraid. Swapping gyroscopes might make a difference but if I had to guess I think the clock speed of the Arduino nano will be the limiting factor here. i.e. the faster your clock the faster your sampling the gyroscope and the more resolution you’ll have.
There was some discussion on this thread on “drift”. I didn’t quite understand it but I think it’s worth your time researching that or prodding that thread for more detail.
