You may have problems with the Logitech Pro 9000, the C600 may be a
better choice since it has fixed focus and you can swap the lens for a
wider field of view. With both of these however, if you are putting this
on a flying robot you may have issues a 'jello' effect caused by the
rolling shutter.
We have been using the Point Gray Chameleon cameras because of this.
