Step 9Operation
The ServerBot is loaded with very simple "Scripts" which tell it how to get from one point to another (turn to heading, drive to beacon, turn to heading, drive distance, etc.). Button are placed on the robot itself so you can press a button to get it to go to a different location. You can also control it via Telnet or IR Remote or a stand-alone PC application which can also be used to load scripts, view sensor data, and issue other commands.
I haven't built one yet, but I intend to place "CALL" buttons in each room which will use an XBee Radio to send a message to the ServerBot, requesting it to come to the room you are in.
Paths can be uploaded at any time. I intend to write a path-builder app to make for easy setup.
A path consists of a list of instructions to get from point-A to point-B. There are three instructions. Turn to Heading (degrees on a compass), Drive x Inches, and Drive to Beacon #x.
It is programmed with how to get from 1 to 2, 2 to 3, 3 to 4, 4 to 5, 3 to 5, and all in reverse. The program will then determine which paths to take to get to the requested destination.
The ServerBot starts and stops gradually so as not to topply anything on the top. When the sonars detect an object the ServerBot will begin to slow-down and eventually stop if something is within 18" in front. It will then continue on it's path when the object (dog) goes away. A physical Bump will cause the ServerBot to backup, move to the side a few inches, and continue in the proper direction.
In Loop mode the ServerBot will continuously travel from room to room, which could be useful in an office enviroment for mail delivery or coffee service. When you need to add or remove something to the tray, you just stand in front of it and it will stop and wait as long as you are blocking it's path.
