Continuity mistake: When Bob Morton, Johnson, and Kinney get off the elevator, a computer voice chimes that it's floor 95. After the board meeting, Morton and Johnson leave the board room (and it's the same floor as you can see the two paintings on the wall that lead to the board room) a sign next to the elevator says "120." (00:07:05 - 00:13:40)
Continuity mistake: When the executive is shot by Ed 209 near the beginning, we see bullet holes in his back, so they're obviously going through, but there's no damage to the windows behind him. (00:11:30)

Continuity mistake: RoboCop walks past the police department lobby for the first time, following Bob Morton. Robo is walking at a very slow, deliberate pace. The rest of the cops in the department run as fast as they can to the far end of the building to see where they are taking him. Despite running about four times faster than Robocop he has already cleared the end of the hallway and is in the regeneration room before the cops get there. (00:29:50)
Continuity mistake: In the beginning when the tracking device is shown, the dot is red and the building outlines are orange. When Dick Jones is holding it later, the dot is white and the outlines are red. (00:30:20 - 01:08:05)
Continuity mistake: When the bearded man is robbing the convenience store, he demands that the owner opens the safe. Look at the Lite cans on the safe. When seen from the right, there are four cans. When the owner kneels down to try and open it, there are now three. When we cut back to a view from the right there are again four. Finally when the robber is shooting at Robocop there are only two. (00:33:20)
Continuity mistake: The bullet holes on Robocop in the convenience store appear /disappear between shots. (00:35:05)
Continuity mistake: When the guy holding the mayor hostage gets thrown out of the window, we see the only two TV cameras near the location follow his fall down to the ground. A few seconds later on the news though, the footage is the same shot we saw in the film, staying focused on the window. (00:39:55)
Continuity mistake: When the official is blown out of the window of City Hall, he falls out of screen. During the replay of the scene for the news immediately afterwards, the stunt man's feet are seen popping up into view as he bounces on the padding and rolls to take the impact. (00:40:00)
Continuity mistake: In the scene where Emil is robbing the Shell gas station, he puts the machine gun in his right hand. But when Robocop drives by and sees him from a distance, the guy has the gun in his left hand. When they cut back to the close-up again, it's in his right hand again. (00:49:35)
Continuity mistake: When Robocop looks up his old address, his house number is the 500's on Primrose Street, but when he drives by the sign on his street it says he is in the 3000's section. (00:54:15)
Continuity mistake: When Clarence is in Bob's house killing him, he sets a grenade on the table. If you watch carefully after Clarence pulls the pin out of the grenade, the timer is actually facing towards Bob as it is set on the table. When Bob crawls over to it the numbers are facing towards the camera, so we can see it counting down. (00:58:33)
Continuity mistake: When Clarence sets down the grenade on the table, we can see that there is a glass to the left of the grenade. When the view changes so we can see the whole room the glass has moved to the right of the grenade, then when we see Bob reaching for the grenade, there is no glass on the table. (00:58:34)
Continuity mistake: When Bob is reaching for the grenade on the table, we can see that there is cocaine all over the table, when the camera view changes to Dick's face on the TV and back again to the table, it's clean. (00:58:48)
Continuity mistake: When Robocop is fighting Clarence Boddicker in the cocaine factory he throws Boddicker through a plate glass window. If you watch closely, you can see the window shatter about 1-2 seconds before he goes through it. (01:05:40)
Continuity mistake: The blood Clarence spits on Robocop's visor disappears after he gets thrown through the window. (01:05:40)
Answer: When Bob Morton is told by a tech that one of Murphy's arm was saved, Bob stated that he wants total body prosthesis. Meaning Robocop's entire body was synthetic. None of his actual body was used. The only thing that was used was Murphy's actual face.
Also, his human brain, and possibly his spine, where OCP could wire him into the suit.
