I believe you are remembering "Eliminators," which features a cyborg
called "Mandroid" that can roll like a tank. This movie was released n
1986, a year earlier than "Robocop," to which the storyline has many
similarities.
Here you'll find a nice plot description:
"The Mandoid was once a pilot who was badly injured in a plane crash.
Reeves rescued him and turned him into a cyborg. He can't remember
anything else about himself, and he wants to kill Reeves. Hunter
decides to accompany him on his quest, taking with her a little
annoying robot called Spot. They hire a guide, Harry Fontana head for
Reeves secret compound. Along Fontana and Hunter are kidnapped by
Cavemen that Reeves brought to the present, and are rescued by Kuji
Takada, Dr. Takada's ninja son, come to find out what happened to his
father."

And this page not only has a nifty synopsis, but offers audio clips
and still photos:
"I think that one of the reasons "Eliminators" comes off better than
many budget (read: crap) science fiction movies is the work put into
the "Mandroid." John can freely detach and reattach limbs, but so can
robots or cyborgs in other films. However, he has a unit on his back
that appears to be a cooling system - a human radiator so to speak (no
Frank jokes). Also, the "mobile unit" is extremely cool. By detaching
his legs, the cyborg can mount his torso on a tracked chassis. It
makes John look like something straight out of Star Frontiers. If
anything, the shortcoming is that the mobile unit only increases the
mandroid's speed over fairly level ground."

The IMDB provides some mini-reviews by users, and a list of the cast:
"If it took itself seriously it wouldn't be much fun, but fortunately
it has a light touch. A man who is half machine, the "mandroid" John
Doe, goes on a quest to find and kill the mad scientist who installed
the half-machine part. Joining him are a scientist (Denise Crosby), an
R2D2 wannabe, an Indiana Jones wannabe, and a ninja! Along the way,
there are boat chases, a barroom brawl, inept bad guys, Roman
soldiers, and goofy physical comedy."
