I don't see robocop being any more battle effective than a sentinal....sentinals were designed to take down cyk, jean, iceman, and beast....wolverine's cleaved hrough his share of those with enough ease...
also in the lazurus project story arch...wolverine was stacked up against a robot who possessed a gifted fighting ability, strategic tragectory assessment skills, had armor that wolverine couldn't cut through at first, and a robotic healing factor that memiced wolverine's.
durin their second encounter wolverine got pissed and finally had enough of the damned robot....then he found he could cut it with ease while pissed off...he kep slicing it, it kept repairing itself....he said he'd keep at it all day until he hit something vital.....that's exactly what happened and he put the robot at his mercy....
finally there was shiva..another robot fighter...shiva had armor that was claimed as being second to adamantium (or second rate adamantium I can't remember which), he had super speed, enhanced reflexes, flame throwers, rockets, lassers, super strength...(far stronger than sabretooth so probably about the class 10 range)...and...."the triggers" some sort of energy emitor that tapped into wolverine's and sabretooths brains and released a bunch of reality altering memories that were painful beyond desctription...the triggers were created as a failsafe to completely nutralize the weapon x projects....YET...both wolverine and sabretooth over came the triggers in their respective fights wih different shiva robots (just thought I'd clear that up as they never fought shiva together, rather 1 on 1.). FINALLY...shiva not only had a program which had downloaded wolverine's fighting style, making him able to predict wolverine's movements....he also had a program which allowed him to make revisements in his system....thus...you can never kill shiva the same way twice...of course that didn't quite matter all that much to wolverine as he ripped it into a pile of debris on several occasions...
sorry, but I just fail to see how a slow guy with considerably less strength than wolverine's average foe, and a reliance on bullets to bring logan down is going to win...all things considered.
