Thank you quazar but i am still having problems getting the servo to move. It is as if the servo doesn't respond at all. According to quazar, the arm should move at a 30 degree angle down and 30 degree angle back up and if no input then I want it to not move.
Ofcourse this doesn't work because it was way too easy. Does someone know what I am doing wrong? Just to be clear, I haven't used RobotC - my advice was based on looking at the guide I provided a link to. Also, the number provided to the routine isn't degrees; it is just a scalar value. Forefront Security License Agreement Number Programs. In practice, each increment corresponds to about 1/2 of a degree of movement, but that is just approximate and may vary slightly between servos.
I am trying to insert servos into the teleop program, but they are not working. I am just trying to have the servos move to one position at the beginning at the. Operating Two Servos with the. For example, in a two-wheeled differentially-steered robot you might call one servo object. And type the program as shown.
As for what is going wrong, it's hard to say. If you have the program successfully driving a motor, then you should be able to plug a servo into that same port and get at least some motion. It really should be that easy - it is with EasyC and MPLAB. Are you certain that your servo works? Yes i am sure my servo works, but where in that article does it talk about a servo. All of it is just basic commands that i already knew. By googling i found this article: That thread has some confused information on it, though it looks like jkjellman has it right.
Vex Motors and Vex Servos use the same signal. If one works, the other should. The PWM value sets position on a servo, and speed on a motor. For MPLAB and EasyC, the range is (0.255), whereas it looks like RobotC uses (-127.127).
For motors, the lowest value causes it to run full-speed CCW, the mid value causes it to stop, and the highest value causes it to run full-speed CW. Values in between set intermediate speeds. For servos, the lower value causes it to move as far CCW as it can, the mid value causes to to return to center, and the highest value causes it to move as far CW as it can. Values in between set intermediate positions. The Game Michael Douglas French.
This is just the way the vex motors and servos work, and it really doesn't matter what language you use. If a Vex motor runs fine, but a Vex servo does not when plugged into the same port, running the same software, then I'm not sure what to tell you. But i am still confused on what they are saying so it didn't help me.

You don't need PID software to drive a Vex servo, since the position sensor and PID control logic are already built into them. Cheers, - Dean.
