I want to access usb port of raspberry pi of my robot. I have a program which is stored/run on pi of my bot and give me some values as results. How can i modify that code so that it run in my PC and access the output from USB port of pi ? I just want to access it in my PC. i am using turtlebot burger with ubuntu 16.04 and kinetic. Can i use rossserial_python for this purpose? If yes, then if you could share some example or suggest me how to use this?

This is not what rosserial is designed for, you'll need to use a different approach.

The way to solve your problem using ROS is not to connect to the PIs USB port from your PC but to run a ROS node on the PI that collects the sensor data you need, then publishes via a topic to other nodes (and computers) on the network.

If you follow the python publisher tutorial you'll see how to publish data to a ROS topic. If you combine this code with the code you're using now to read data on the PI then you can publish the data on a topic to all ROS nodes.

Hope this helps.
