Check first if the camera you are using works with any existing ROS nodes that work with cameras. If one does then you will just need to install that on the robot (along with a ROS base install). Then you will not need to write code to get a camera feed working, just run that node on the robot that already works with the camera, and image view or rviz on the desktop will be able to display the image (with roscore running on one of the machines).
