How do you calculate that ticks per meter defined in the launch file.

[siddharthbhurat4]

The ticks per meter defined in the launch file is the fixed number we need to use or we need to calculate it for our own case. If we need to calculate it for our case, how to do that. I am confused because I am not able to understand how do these ticks coming from the encoders related to the PPR or CPR given for that particular motor. The motor I am using is the gobilda motor. Please can I know how to do it?

Thanks
