I am working on a project of finding the bevel angle of a worm drive blade. To find the angle, I have decided to use 2 accelerometers. One of it being my reference and will sit on the footplate, the other one will be on the housing and moves with the bevel pivot.
I want the accelerometer sitting on the footplate to be my reference. Hence, whenever it moves, gravity will be perpendicular to the accelerometer. This is of course impossible to create because gravity is always pointing DOWN!! Is there a math equation or algorithm such that it would take the G values of the footplate accelerometer and create a " nonconventional, pseudo" gravity ?
Please let me know if there is any clarification needed. I am using the MPU6050 accelerometer.
