The Enforcement Droid Series 209 (or ED-209) is a fictional character featured as one of the design and special effect highlights of the 1987 movie RoboCop, and its two sequels. ED-209 serves as a heavily-armed obstacle and foil to RoboCop’s title character and others throughout the series, as well as a source of comic relief due to its tendency to malfunction and lack of intelligence. It is an often referred to, and lampooned, fixture of American popular culture.
The ED-209 was designed by Craig Hayes, who also built the full size models, and animated by Phil Tippett, a veteran stop-motion animator. Davies and Tippett would go on to collaborate on many more projects. As one of the setpieces of the movie, the ED-209’s look and animated sequences were under the close supervision of director Paul Verhoeven, who sometimes acted out the robots movements himself.
Director Paul Verhoeven made it clear very early on that ED-209 should not look “cute.” He wanted the robot to look hard and mean. For this reason, various common robot features were left out. There are no eyes on the ED-209, for instance, since Craig Davies believed they conveyed too much emotion as well as being clichéd. According to RoboCop writer Ed Neumeier, the ED-209 robot was designed to resemble a bipedal Vietnam War-era Huey helicopter.
Craig Davies also incorporated his ideas about modern 1980s American design, especially car design, into the robot. He envisioned futuristic designers making the robot look good in order to make it marketable before they made it work well, “just like an American car.” The crew commentary audio track on the Criterion Collection DVD release confirms the obvious commentary on ridiculous corporate design policies, with such features as an obviously over-designed hydraulic system, over-attention paid to cosmetics and the placement of obviously vulnerable features such as the radiator grill on the very front of the robot.
The audio for the ED-209 was composed by Stephen Flick and John Pospisil of audio effects company Screaming Lizard. The hydraulic heavy machinery feel of the robot was composed of various motor and piston noises. An intimidating growl produced by ED-209 in the first movie was created by playing a jaguar growl backwards. Its distorted human voice was recorded by the film’s executive producer Jon Davison. It was never intended to be in RoboCop’s theatrical release and was only recorded for an initial screening. However, it was kept as the voice of ED-209 all the way to the theaters.
The original full-scale 'ED' currently resides at Tippett Studios in Berkeley, California, as well as the original stop-motion puppets. Though the puppets have seen better days, the full-scale model is in remarkable condition. The paint and armament scheme was reconfigured for RoboCop 3, and is how the full-scale ED-209 is preserved.
The ED-209 is featured in every RoboCop major motion picture, while it is missing from the series’ direct-to-video releases and the television series.
ED-209 is primarily featured in the first film, where it appears three times. The 209 series was an attempt to create a series of law enforcement robots, the brain child of the movie’s main villain, OCP Senior President Dick Jones. During its unveiling to the OCP board, it malfunctions and brutally kills an OCP executive, Kinney, even though he had complied with the robot’s orders to “surrender” and put down his gun (Why this demonstration model is loaded with live ammunition on this occasion is unexplained, and could simply be a plot device). Because of this disastrous malfunction, the RoboCop program is given the green light.
The ED-209 appears again when RoboCop confronts and attempts to arrest Dick Jones. The robot seriously damages RoboCop in a brief battle. However, ED-209’s faulty nature is again highlighted when it trips and becomes disabled while attempting to traverse an ordinary flight of stairs. It also loses an arm during the battle when RoboCop forces the other arm into it while it fires.
The robot makes his final appearance stationed in front of OCP Plaza, protecting the building during a police strike. When it attempts to interfere with RoboCop (saying he is "illegally parked on private property"), he destroys it with a Cobra assault cannon taken from Dick Jones and Clarence Boddicker’s minions. RoboCop fires the weapon twice, the first shot incapacitating it and the second annihilating its upper half.
 RoboCop 2
RoboCop 2 features only quick cameos of the robot, where it is featured as a security bot for an OCP building on a television news report. The robot promptly trips on an open manhole and flails about uselessly while trying to disperse demonstrators.
A full-scale model (or out of commission) ED-209 also appears in the background as the executives are discussing their problems with the RoboCop 2 program.
In the widescreen version of the film, just before the Mayor enters the OCP CEO’s office, an ED-209 unit is spotted standing on the right side of the screen outside the building.
 RoboCop 3
RoboCop 3 has one scene of ED-209 once again used as a security bot for an OCP building, this time an armoury. Resistance fighters are able to easily hack the ED-209 via a dataport in its leg with a portable computer (“I am now authorized to...be loyal as a puppy”). The ED-209 is promptly turned against its owners, and opens fire upon OCP security personnel.
 Animated Series
ED-260, the upgradable version of the Enforcement Droid Series 209 has made numerous appearances in RoboCop: The Animated Series, but did not appear in RoboCop: Alpha Commando.
 Video Games
The ED-209 is also used as a boss in RoboCop computer and video games, and the video game RoboCop versus The Terminator.
There were two ED-209s in the comic RoboCop versus The Terminator (though it is mentioned that there are 200 of them deployed), assisting RoboCop in shooting down Terminators bent on killing Flo. However, their limited intelligence remained a problem. In one instance, when ordered by RoboCop to “scan for cybernetic activity,” the ED-209s immediately registered RoboCop as a target and opened fire, hitting each other by accident.
In Marvel’s 1990 RoboCop comic, OCP Vice President Donald Johnson orders the creation of the ED-309.
The ED-209’s primary weapon in all films are three machine guns, two on the left arm and one on the right arm. The left arm contains two external high-capacity ammo magazines and the right arm one which snap into place when the guns are armed. It also featured a three-round rocket launcher on its right arm and twin launchers for mortar rounds or gas grenades behind its head. The grenade launchers are never used on film, but are shown on models and schematics of the ED-209. It is also discussed in the first film that once it's proven itself in Delta City it would be marketed to the military, explaining the extremely powerful weaponry for a police droid.
 ED 209 in popular culture
* In the DuckTales Super DuckTales storyline, Gyro Gearloose builds an electronic bodyguard called GICU2 to protect Scrooge McDuck's Money Bin, which is clearly based on ED-209, as it also malfunctions and tries to kill the ones he was supposed to work for. This leads to creation of GizmoDuck, who, in turn, was partially based on RoboCop.
* In an episode of The Simpsons (“I, D’oh-Bot”), Homer fights an ED-209 look-a-like built by Professor Frink and his son in a robot-fighting television show called Robot Rumble.
* In an episode of South Park (“Korn’s Groovy Pirate Ghost Mystery”), Kenny wears a life-sized ED-209 Halloween costume. Coincidentally, in the RoboCop film, the ED-209 malfunctions and kills a man named “Kinney.”
* Another South Park episode, “A Ladder to Heaven,” featured an ED-209; in this episode the ED-209 is depicted as guarding a house.
* In another South Park episode, “The New Terrance and Phillip Movie Trailer,” the television transforms into a ED-209 because of the confusion with the TV remote.

It attacks her even after she complies.

Isaac Sumdac even mentions a slight malfunction with one of the robots harming the Police Captain’s wife previously. However even the new robot droid is seen malfunctioning one way or another through out the series.
