PeterH thank you for this much support, my aim is to do the project to learn something and I'm ready to try different direction that I took at first. So let's do it the way you suggest, but I've doubt I fully understand you in this (to measure gyro).
Do you mean that I post here simply information like:
- if I keep robot stationary, output of gyro is x
- leaning forward fast to around 45deg I get y
3...
or what best way to answer your question "output of gyro" please?
