Revealing mistakes: Right after Robo is hit by the grenade, you can see that the bottom of his feet are not covered.

Continuity: In car chase with armored van, we see Robocop's car with the roof missing before it gets blown off a few seconds later.

Revealing mistakes: When in pursuit of two Splatterpunks, Robo walks through a window that shatters before he touches it.
Continuity: When flying over the battle, Robocop's visor is cracked, making his eyes clearly visible. The visor is intact when he crashes into the OCP control room.

Continuity: During the fight with Otomo, in the shot just before Robocop's leg opens up to reveal his pistol, his pistol appears to be already lying on the ground beside him.

Continuity: When Lewis and Robocop confront McDaggett, wounds are visible on Lewis' arm, even though she hadn't been shot yet.
Audio/visual unsynchronized: When one of the Rehab officers shoots Robocop when he's torching the staging area, in the over-the-shoulder view of the officer, there is no muzzle flash from the M16, he's clearly faking the recoil, and the sparks from the "bullets" are on his chest even though he's aiming at his head.
Errors made by characters (possibly deliberate errors by the filmmakers): There is no reason for RoboCop to shoot through the roof of his police cruiser in order to get out. The driver's side door was undamaged and should work just fine.
Revealing mistakes: When the Otomo attacks RoboCop, you can clearly see the floor bounce a few times every time he lands.
