I feel like this is a dumb question, but I am going to ask it anyway.
I have been playing around with the vision examples that come with MRL. These are very cool and work well. The OpenCV GUI is very nice and friendly. It is what brought me to MRL. Playing with faceTracking.py, I see that that the location and size of the box is printed to the python window. My question is this, how would one send this data across a serial port?
On many robots, when they move their arm, it tends to sway back and forth as the motion stops. Do you use some sort of sensor system, and active control to compensate for this swaying?

Here are some amazing software projects which warrant being assimilated into MRL ! RESISTANCE IS FUTILE !
Please add your favorite open source Java project to the list as a comment !

Here Leonardo Triassi has made a spectacular InMoov and its now running some of the same scripts from the InMoov service page. Soon they will be sharing Brains !!! Great work Mr. Triassi !

Most of the services I created manually, and used the gui to connect the services methods together.
Like joy.xaXisRaw - > panServo.move()
Here is a Python script to listen for the a certain button press:
