Is there an alternative way to connect to machines through the same ROS?
I want to connect two microcomputers (Odroid or Rasberry Pi) together by ROS.
As I found in http://wiki.ros.org/ROS/NetworkSetup, it seems that two machines can only be connected through network, such as wifi. Can I connect two ROS computer through physical connection, such as USB? If so, how to implement it in detail?
I am new for ROS. Thanks very much.

Via USB? It's not possible AFAIK. What transport protocol would you use through a USB serial connection? You can certainly write your own.

Do you mean that generally two ros machines can be only connected through wifi?

Wifi or LAN.

If you have an Ethernet (RJ-45) port you can use that too.

just a small comment: the 'only' requirement for ROS is that you have a working IP network (ignoring things like rosserial here obviously). If you can use USB networking, then that should work as well.
