FindHuman Service

javadoc

Attempts to find humans through OpenCV facedetect. Utilizes a pan / tilt kit and LKOptical track points to track human after detection.

 

 

So far you have to use Eclipse and change the FindHuman.java file in the service directory to set your Arduino pin and com port settings, etc. Then start it like you would any other MRL Service.

Serial Communication with Arduino?

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?

Controlling pendulum-like oscillations?

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?
