ROBOT_STATE	Refer to the Definition of Enumeration Type

Example

#include <thread>
#include <chrono>

if (drfl.get_robot_state() == STATE_STANDBY) {
    if (drfl.get_robot_mode() == ROBOT_MODE_MANUAL) {
        // Manual mode
        drfl.jog(JOG_AXIS_JOINT_3, MOVE_REFERENCE_BASE, 10.0f);  // start jog
        std::this_thread::sleep_for(std::chrono::seconds(2));
        drfl.jog(JOG_AXIS_JOINT_3, MOVE_REFERENCE_BASE, 0.0f);   // stop jog
    }
}

This example checks the robot’s state and mode before motion. When the robot is in standby and Manual mode, it performs a short jog motion on joint 3. No motion is executed otherwise, ensuring safe operation.
