basically what i'm trying to do is make the servo move like a clock pendulum, back and forth through the entire range of movement

i want it to start when the vex module is turned on, but if there is any way to link it to run whenever the robot is being actively controlled (i.e., the controls are being manipulated), that would be great, although it seems like it would be very complicated

btw we're using the tank 2-motor "block" (i guess thats what you'd call it) to control the robot's movement.
