MrlComm 54

Hi,
 
With the new version, this code doesn't work.
 
  MrlMsg msg(PUBLISH_CUSTOM_MSG);
  msg.countData();
  int i=0;
  while (mrlComm.getCustomMsgSize()){
    int x = mrlComm.getCustomMsg();
    //MrlMsg is the class that build message to send to MRL
    msg.addData(x);
    i++;
  }

MRL Error

See the bold? But that path and file DO EXIST under my ../mrl/ and ../mrl/lab/
so why the error? and how to stop it?
 
17:01:49.757 [python] INFO c.m.s.Python [Python.java:533] exec(String) 
from org.myrobotlab.service import Serial
arduino_serial = Runtime.getService("arduino.serial")
 
 

Output data from 'Floorfinder' in opencv.

I am searching for a couple of days now. Where can i find wich opencv plugin, like floorfinder, outputs wich value? I used the roborealm floorfinder plugin before and that outputs the highest pixel within the selected "floor" area. Does the myrobotlab plugin work the same?

Sill a newb ... having trouble with a NameError 'serial' is not defined

I got this 3 yr-old code for OpenCV to track a face and send the coordinates to an Arduino. I've confirmed that my Arduino is using com3. But as stated above, I'm getting a Name error telling me that 'serial' is not defined and so won't establish a connection to com3. I'm way too inexperienced with MRL to know how to chase down the serial function, so I'm asking for help.

I'm a newb and need help with Python imports for Opencv

Hey everyone! Excellent site! I'm a Python/Java newb in need of help. I just installed the current MRL and the latest Java (9). I tested the Opencv face-tracking on the GUI interface and it tracks my face fine on my built-in laptop camera.
