Our group wants me to program the nxt motors to act like a servo. I am not sure how to go around with that so they zero out on a position and then using the joystick to change the angle, does anyone know how to program that?

well, you could just do 1 of two things.

1. Program the servos straight to the joysticks.
servo[servo1] = (joystick function);

2. Set the servos to a variable where the joystick value "adds" to the position so that the servo doesn't move back when the joystick is centered.

int a;
servo[servo1] = a + (joystick function);

They want an nxt motor to act as a servo, not use a servo sunny.
try using an encoder function. nxt encoders are 360 ticks per revoplution. dowside is that you need to know which way you want the motor to go. ill attach some code tomorow as i dnt hv time rt now.
hope this helps

The trick with using an NXT motor as if it were a servo is to remember that you can't just tell it to go to a particular position. You can, however, tell it to go either forward or backwards until the encoder reaches a particular count. You also do not have any way of asking what position the motor is in at the start of your program. So, you will want to ensure that you move the motor by hand to a known starting position before starting your program. Let's say, as an example, that you want to call the starting position 0. That makes things easy. Just define a function like so:

My mistake, I read the question wrong. I through they wanted to control the servo with a joystick or something. .
