Measure speed of rotation pole

Projects General Guidance
1

Hi Forum,

I am working on an Arduino project and needing a bit of help.

I need to measure the speed of rotation of a long pole (shaft) that also moves around on other axes. I can measure a fixed rotating position but how do I get a value if the pole is moving on other axes in a fairly random way? (i.e. it is being held and moved around while spinning).

Currently, I'm using the MPU6050, which is working, but I'm struggling to process the values.

I'm open to any suggestions and would be really grateful if anyone knows of any code I might use. If need be I could source another board rather than MPU6050.

Hope that makes sense, thanks.

Is the MPU6050 mounted to the pole? Fixed to it, so that one of the gyro axes is parallel to the axis you're trying to measure?

More info (images at least) needed, as I am having a problem imagining what you're up against.
