set_state_led_off (Manual Mode)

This section explains how to use set_state_led_off during Manual (Teach) operations. This function turns off the robot’s State LED completely. It is often used when you want to disable LED indication temporarily during maintenance or quiet operation.

Typical usage

  • Turn off LED illumination during manual operation or diagnostics.

  • Use when LED light may interfere with visual calibration or camera sensing.

  • Disable LED to indicate a “paused” or “standby” condition.

Example

#include "DRFLEx.h"
#include <iostream>
#include <thread>
using namespace std;
using namespace DRAFramework;

int main()
{
    CDRFLEx drfl;
    drfl.open_connection("192.168.137.100");

    drfl.set_state_led_off();
    cout << "[LED] State LED has been turned off.\n";

    this_thread::sleep_for(chrono::seconds(3));
    drfl.state_led_reset();  // Restore LED afterward
    cout << "[LED] LED reset to default state.\n";

    return 0;
}

This function disables all LED output, allowing manual tasks to be performed without LED distraction or ambient light interference.

Tips

  • Use to indicate a standby or inactive state during teaching pauses.

  • Combine with state_led_reset to restore LED behavior after maintenance.

  • Helpful when performing camera calibration or light-sensitive operations.
