In the latest issue of the US version of Sky and Telescope, there is an article of someone who has "motorized" his dob collimation...
I've not read the article in detail yet but it looks like he has put a motor on each collimation screw via a system of pulleys and gears/steps with the controls near his eyepiece...
While complicated to "two left thumbs" me it at least looks like it eases the completion of a star test and collimation is a "one man job"...
