Continuity mistake: When the girl is spraying graffiti on Robocop, the last mark on his head is a light dot. Yet a moment later when shooting at the smoker, it's a bright orange line.
Visible crew/equipment: As Robocop is stood up after electrocuting himself, the crew and equipment is reflected on his front.
Continuity mistake: When all the cops go into the nuke factory and one cop is hit in the leg, the other cop puts his hand over a bar and yells "give me your hand." As he pulls him, his hand is now under the bar, even though he never let go of the cop's hand. (01:02:00)
Factual error: At the beginning, when those guys robbing the gun store blow Robo's car all to hell, it bursts into flames before he gets out. If he were in the fire, his human face would burn off, being regular flesh.
Continuity mistake: Robocop shows up at the presentation of RoboCain, but he disappears in the wide shots, only to suddenly reappear when the shooting starts.
Continuity mistake: When RoboCain steals the remote control, there's a woman in black walking up the bleachers. A shot later, right when RoboCain clicks the button, the woman is suddenly way behind.
Continuity mistake: When RoboCain smashes Robocop against the wall, the shape and size of the hole, plus the cracks around, change 4 times during the fight, depending on the shot.
Continuity mistake: When Robocop lectures the kids about the hydrant, they are suddenly standing closer together between the first and second shot.
Visible crew/equipment: When Robocop talks to the baseball kids, the moving boom mic is reflected on his helmet.
Revealing mistake: After Robocop kills the man holding a baby, one can see the baby is a doll.
Revealing mistake: When the truck drives through the bar, the brick walls are a blatant thin piece of painted cardboard.
Revealing mistake: When Robocop is on the bike, he does a skid. in the exact place where he does this, there is already skid marks from previous takes.
Continuity mistake: When "Robocop 2" goes beserk, he shoots several civilians and a row of OCP security. The last civilian to be hit in that scene is later seen being helped down a flight of stairs by two folks as the President of OCP talks with some of his subordinates about who to lay blame on for the incident.
Revealing mistake: The Mayor looks into the armoured van at the money, and picks up a gold bar. It looks bad, is obviously too light to be gold, and doesn't clink when put back.
Answer: To answer the first question, it's some sort of tubing and fluid from inside of Robocop... so something like oil or something along those lines. Something that Robocop's robotic body uses to function. As for the second question, I do not believe it's ever mentioned specifically, but online searches say it's over 300 new directives. (Though we never see all of them).
