Robotic Arm Project

My newest project: a robotic arm controlled by a joystick.· Maybe someday I'll break myself from these VB6/Joystick/BASIC Stamp projects and try something else, but for now:
Can some explain to me how a continuous servo works?· I'll put any number 0-1500 in PULSOUT to my servo and it always seems to spin clockwise at different speeds regardless of the size of number I put in.· Is there a way to control the continuous servo at variable speeds and bi-directional.· I've gotten a standard servo to go both ways without a problem, but I need to be able to rotate beyond 360 degrees.·
I don't want to use a DC Motor because the electronics are so simple for a servo and size is somewhat of an issue.
Thanks !

main: PULSOUT ServoPin,1200 '0 - 1500 I know what this means to the stamp, but what does it mean to the servo GOTO main

what kind of servo are you playing with? If it is an off the shelf RC servo, chances are you might have to modify it for continuous rotation by disassembly of the servo to hack out a bit of plastic and to disengage and set the feedback resistor.

As for the pulseout cmd and what it does for the servo you can go to
http://www.geocities.com/BourbonStreet/3220/servobasics.html
for the skinny on servo inputs.
Chapter 2 in http://www.parallax.com/dl/docs/books/edu/RoboticsV20.pdf·would also be useful to you.
