I have a proof of concept working with OpenCV running on a PC and using a Logitech webcam we had lying around. I have very professionally taped the webcam to a servo that I am driving from an arduino. The python code is interfacing with the arduino over usb serial.

I have ordered the hardware for the robot and am awaiting it's arrival. Once I get OpenCV up and running on the RPI3 then I will work on the hardware interface on Rosie.
