Hi, I'm a new users of ROS, so I need a lot of advices.

I've a sensor based on UWB technology that provides cartesian coordinates (x,y,z) as output. This sensor can be connected through a serial port.

What I'd like to have is to use data from my sensor to locate and navigate the robot. So what I need is a package that allows me to read data from my sensor and then use them to localize and drive the ROS-robot instead of using data from the sensors which are integrated on the robot.

Pratically I have to:

1: read the data (x,y,z) from a serial port

2: use my data to locate and drive the robot

How can I implement this two things?

@gvdhoorn I'm sorry but I didn't tried anything, I'm a new user of ROS, I know nothing. I'm asking for some help

Taking someone from "nothing" to everything you ask is going to be rather time-consuming. We're all here to help, but we do like to see some initiative on the part of the poster.

Have you read the posts I linked you to?

@gvdhoorn yes I' ve read your post but they are mostly concerned on the navigation. First, I need to learn how to read a serial port and use data from that. I'm trying to understand how this example works: Do you think this a possible idea to read data from a serial port? I think this could work
