55 Robotics Pan/Tilt Mechanisms part1
A common robotic need. Most pan-tilts sold today by companies such as
Pelco and Vicon are for CCTV applications for continuous scanning or
remote operation. At most these will have potentiometers for feedback.
A number of undersea companies make pan-tilt devices as well that are
rugged and nicely packaged, but these tend to be heavier and more
expensive than their terrestrial counterparts.

Instead of a conventional camera, you use one with a very wide
fish-eye lens. The (very distorted) image is then sent thru a box that
digitizes and processes the data in order to simulate a regular
camera. You can (completely in software) pan, tilt, rotate, and zoom
the image with great flexibility. $10K.

An all-electronic pan/tilt/zoom resampler. That is, they put a box
behind a camera with a fish-eye lens. The box has digital inputs for
pan, tilt, zoom, rotation. The box resamples the video signal and
produces an output as though the image were acquired by a camera with
those parameters. Used as an alternative to pan/tilt devices.
