Hello,

I need your help with the following:

Imagine a rod rotating about a point, its location is unknown. My objective is to find where that point is. If I place two gyroscopic/accelerometer sensors (mpu6050), one at each end, and read the centripetal acceleration. Using the following formula Ac=W^2/R, I can find the distance between the sensor and the instant center of rotation.

1-is this feasible? Are the results a accurate? 2-Is raw data reliable enough to do this calculation or should I use some kind of filter? 3-Now imagine I am holding the rod and i'm moving it sideways, would it mess with the results? I've low programming skills but its not my first time playing around with this sensors on arduino.
