You only need to make the thread in one place. Far as I aware, most of us are in the Eastern Standard Time Zone (GMT-5), so we might not be able to respond immediately.

As for robot, well they are written in java, so a basic primer on java programming might be helpful. If you have never programmed before you might want to read into it first. It is a pretty abstract science.

Aside from that, a robot is just a Java Class with special methods corresponding to specific events that robot may encounter. Such as the onScannedRobot event which occurs when an enemy is scanned, or the run() method which occurs when the robot is started. You can read up on the basics of Robocode robots.

If the program is confusing, you can check out the Getting Started page. If you just want to jump right into the deep end, there is the My First Robot Tutorial.
