set_on_monitoring_data

This is a function for registering a callback that automatically monitors the robot’s operation data such as joint positions, task coordinates, and system status. It is useful when certain tasks must execute automatically upon data updates.

Definition
DRFLEx.h within class CDRFLEx, public section (line 613)

void set_on_monitoring_data(TOnMonitoringDataCB pCallbackFunc) {
    _set_on_monitoring_data(_rbtCtrl, pCallbackFunc);
};

Parameter

Parameter Name	Data Type	Default Value	Description
pCallbackFunc	TOnMonitoringDataCB		Callback function pointer to handle real-time monitoring data updates

Return
None

Example

void OnMonitoringDataCB(const LPMONITORING_DATA pData)
{
    // Displays the current joint position data
    cout << "joint data "
         << pData->_tCtrl._tJoint._fActualPos[0] << ", "
         << pData->_tCtrl._tJoint._fActualPos[1] << ", "
         << pData->_tCtrl._tJoint._fActualPos[2] << ", "
         << pData->_tCtrl._tJoint._fActualPos[3] << ", "
         << pData->_tCtrl._tJoint._fActualPos[4] << ", "
         << pData->_tCtrl._tJoint._fActualPos[5] << endl;
}

int main()
{
    drfl.set_on_monitoring_data(OnMonitoringDataCB);
}

This example registers a data monitoring callback that continuously prints the robot’s joint positions in real time as they are updated by the controller.
