with very due respect it is stated I am working on unmanned ground vehicle, which is more or less look like a fighting robot with robotic arm mounted on it, I want to know how to control my robot with ps4 gamepad and using ROS.
any advice would be highly appreciated.
I am using raspberry pi 3 as a SBC
The ps4 gamepad should work with http://wiki.ros.org/joy in at least usb wired mode, otherwise bluetooth needs to be set up with your pi.
Some of these instructions https://github.com/solbach/ps4-ros regarding ds4drv should help with running bluetooth (not sure if working that on a pi is different- there are posts in forums elsewhere from people using a ps4 controller to connect to a pi to play games that could help). The actual code in that github repository maybe is a useful example, but not probably not necessary for your robot (it looks specific to someone else's custom robot).
Maybe this https://lifehacker.com/everything-you... is still relevant but it could be easier/different now.
http://wiki.ros.org/teleop_twist_joy converts joy messages to messages you could design your robot to be able to drive with, or you could make a custom node that translates joy messages to something that works for you.

This is a HUGE question. We'll need to know a lot more about your setup to help. Maybe start with just the mobile base, how do you control the motors? Do you have encoders or and IMU?
Yes,i have a motor with encoders
