I am trying to identify a book based on a few scattered details.
There is a cyborg bounty hunter and/or mercenary that experiences some form of discomfort with his cybernetics (possibly the temperature of the cybernetics being uncmfortable)
there are slime-aliens of some sort, and it is possible a character from the story takes l overs from this species. This species may be acidic, and a character may have lost his legs to one.
There is a psychic alien in the book, who may be small, that apparently drank something at one point that was supposed to be poisonous (maybe) but just made him/her drunk.
One of the primary conflicts of the book seems to be that an robot (possibly ancient, and possibly with six arms) is destroying interstellar pathways it created (may be wormholes, may be stargates, may simply be paths of some sort)
The only other details that can be recalled... are that there is some sort of translator box, and some other sort of device with a nuclear/atomic battery.
The book would most likely have been published before the year 2001
And it definitely has a lot of aspects that make it seem like a post-star-wars science fiction story...
