"zumo1" has the name "0"? does not match with the other config files.

the RobotName defined here is the topic or aruco marcer number and has to match the one provided by SSR

Then rename the file. It's confusing that robotName does not match the filename.

Can't you use int64_t in the first place?

you mean because of the repetitive casts?

Can't you use float here?

I'm not 100% sure, but i will try
