  2. Usb cam return int raw(x,y) value and How send it to rc car ?

  3. Does Ros have a command to control a steer?

Hi HoJoOnJung,

We don’t have the experience on this topic, but to connect Arduino with TK1 and use ROS might help you to save some efforts on peer to peer communication.
There are seveeral interesting projects can be found from TK1 wiki for your reference:
