In working with newer boards, I'm realizing that parts and part numbers are getting even smaller, while my eyesight is suffering from old age. In working with the Artik 520 board, I had to dig out a USB microscope to determine the part number of a chip that was only slightly larger than a surface mount resistor.
My thinking is this: I need a robotic arm to hold the camera (or a similar camera). It needs enough granularity in its movement that centering the camera view on such a chip is possible. Accuracy and ease of use is priority. Speed of movement is not. Preference is for non-wireless control. I'd also like to avoid the hefty price tag attached to some of the obviously capable industrial arms. Kits are acceptable.
