Hi, I am probably going to make a robot tripod head controled by an arduino. I already the arduino and I am going to test some motors soon. Using this kind of thing can't you put some kind of position sensors in the tripod head to get the ypr parameters? I thought about some axial sensor, like some based on resistance or something like that. Don't really know how precise they can be. They could be connected to the same arduino on the robot to register the movement. Another possibility is using step-motors. I also don't know how precise they are, but they do preset known step rotation. I also don't know if they would be strong enough to be used on the arm that moves the camera vertically. I was thinking about using a servo there.
Has anybody here already built your own robot? Is the project available? Another thing that can be used with the robot to maybe put the values directly into the exif is the Magic Lantern firmware for canon<http://magiclantern.wikia.com/>. It is a free software and really makes fantastic things. I bet it could read values through the usb connector of the camera (although I didn't search about it).
