Claw Programming

VEX V5 General Discussion

Hi,
I am trying to code a claw so it always closes with motors at 25 power. Pretty much, I want it so when you open the claw, there is a 0.25 second delay to when it automatically closes. When i put the wait command in there, it delays the entire bot. I am using Vex Cortex for RobotC.


if(vexRT[Btn8U]){
motor[Claw] = 127;
}else{
motor[Claw]=-25;
}

Try putting the claw control code in its own task. Something like this.

task clawTask() {
  int delay = 0;
  
  while(1) {
    if(vexRT[Btn8U]) {
      motor[Claw] = 127;
      delay = 25;
    }
    else {
      if(delay-- <= 0) {
        motor[Claw]=-25;
        delay = 0;
      }
    }
  
    wait1Msec(10);
  }
}

task main()
{
    startTask( clawTask );
    while(1) {
      // drive code   
      wait1Msec(10);
    }
}

Oops, never mind my response. My dumb idea would have kept the robot from seeing the rest of your code. jpearman has the correct way.

I showed one way, there are others. You could also use similar code in a single task.
