Programming Servos

the23rdirishman

I am new to robotics, and I can't find anything that explains how to program for the javelin stamp. For example, how would I program the robot to follow the border of a 1x1 meter square? The code should be relatively simple, I just figure out the significance of start(), stop(), and update() in getting the Boe-Bot (Rev to drive in different patterns.

I also don't understand why the following code makes the robot drive straight in some cases, and pulse a few times before driving straight in others:

leftServo.update(230, 2304);
CPU.delay(1000);
rightServo.update(130, 2304);

Get the JBot package located here:
http://tech.groups.yahoo.com/group/JavelinCode/files/Javelin%20Stamp%20IDE/lib/JBot/

Also get the Robotics v2.2 text (also at above link) which uses the basic stamp as the mcu
but that text holds the pictures which are not present in the JBot package.

The·chapters should explain·how·to program the servos.

Is there a version of the Robotics v2.2 text for the Javelin stamp? That's really all I need.

The chapters from the JBot package are the v2.2 robotics text.
Unfortunately Parallax never completed the text and included updated pictures.
So what you need to do is locate the appropiate text in the v2.2 robotics
and then you will find the missing pictures. Although written for the basic stamp
the hardware connections are simular to the javelin connections.
The example code for the javelin is working and as such should be your guide.
