Gripper Servo JS Conversion

Absolutely - here’s a clean ARC JavaScript version of your gripper routines, converted from the EZ-Script behavior you described.

A couple of important notes first:

• In ARC JavaScript, Servo.setPosition() is used instead of Servo(...)
• ADC.waitForLower() is the direct equivalent of ADC_Wait(Adc#,lower,#)
• To stop a servo when the lever switch hits, you’ll typically use Servo.release() on that servo port
• I’d recommend using JavaScript over EZ-Script going forward for this in ARC

1) Open/Close both grippers

// Open Grippers
Servo.setPosition(v25, 180)
Servo.setPosition(v9, 180)

// Close Grippers
Servo.setPosition(v25, 1)
Servo.setPosition(v9, 1)

2) Left gripper IR detect loop

This matches your old Grip_detectL behavior:

while (true) {
  ADC.waitForLower(ADC2, 35)
  Servo.setPosition(v25, 30)
}

3) Right gripper IR detect loop

while (true) {
  ADC.waitForLower(ADC1, 35)
  Servo.setPosition(v9, 30)
}

4) Lever-switch stop routine

Your EZ-Script version is close, but in JavaScript you’ll want to poll the ADC values and then release the servo when the lever switch is triggered.

Assuming:

• ADC6 = right lever switch
• ADC7 = left lever switch
• lever switch reads 0 when pressed

while (true) {
  var rightLever = ADC.get(ADC6)
  if (rightLever == 0) {
    Audio.sayEZB("Object now gripped")
    Servo.release(v9)
    break
  }

  var leftLever = ADC.get(ADC7)
  if (leftLever == 0) {
    Audio.sayEZB("Object now gripped")
    Servo.release(v25)
    break
  }

  sleep(20)
}

Combined example: gripper close until lever switch hits

If you want the servo to move closed until the switch is pressed, this is usually the best pattern:

// Start closing both grippers
Servo.setPosition(v25, 1)
Servo.setPosition(v9, 1)

while (true) {
  var rightLever = ADC.get(ADC6)
  if (rightLever == 0) {
    Audio.sayEZB("Object now gripped")
    Servo.release(v9)
  }

  var leftLever = ADC.get(ADC7)
  if (leftLever == 0) {
    Audio.sayEZB("Object now gripped")
    Servo.release(v25)
  }

  // If both are triggered, stop checking
  if (rightLever == 0 && leftLever == 0) {
    break
  }

  sleep(20)
}

Important correction about "stop"

In ARC, there isn’t really a generic stop() for a servo the way EZ-Script may imply in some script patterns. For a servo, the usual way to stop holding position is:

Servo.release(v9)

or

Servo.release(v25)

That turns off torque/holding for that servo.

ARC Script Skill setup tip

If you’re placing this in a Script Robot Skill, you can use the kebab menu on the Script skill and open Settings, then choose JavaScript, paste the script, and save it.

One thing I’d like to confirm

To make sure the conversion behaves exactly right, can you confirm these two details?

1. Are v25 and v9 definitely virtual servo ports from a servo plugin skill, or are those actual servo ports on the EZ-B?
2. Do you want the lever switch to:
   • release the servo immediately when touched, or
   • hold at the current position by stopping movement some other way?

If you want, I can also rewrite this as a more complete single ARC JavaScript routine with:

• openGrippers()
• closeGrippers()
• monitorGrippers()

so it’s easier to reuse in your project.
