How to get RPM, position of the JetRacer

[salahzerdaoui]

Hello everyone, I’m looking to get the RPM from a Jetracer robot to calculate the speed (I also need to calculate the angle of steering and the position of the robot). I contact the support about it as I cannot find any documentations about it online. But after trying few stuffs, he tells me to try on this forum. So here it is.
If you have any hint, documentation or information that would help me go further with that issue. You’re welcome to post it here.

Thank’s in advance,

Salah
