Robbie the Robot

Dr. Morbius creates Robbie after having his intellectual capacity doubled by the Krell machines. The robot is a man-sized, highly capable domestic servant receiving orders aurally, and responding as needed with a synthesized voice of his own.

Robbie exits the cockpit of his vehicle.

Robbie invites the men inside.

Robbie first appears steering a special vehicle to pick up the officers. It is specially built for him, accommodating his inability to sit down. From this position, he can wirelessly maneuver the vehicle, and even turn his head around to address passengers.

Robbie fires Adams’’ sidearm.

Despite his having only two wide, flat fingers on each hand, he is able to grasp and manipulate objects as a human would. To demonstrate this, Morbius has him aim and fire Commander Adams’’ weapon at a nearby tree. How he pulled the trigger is something of an unanswered question since his hands are hidden from view as he fires, but he does so all the same. This makes him quite useful as an interface, since he is able to use any of the devices already in the environment. Additionally, should he become unavailable, humans can carry on in his absence.

Alta thanks Robbie for offering to make her a new dress.

Given that he must interact with humans, who have social needs, his stature helps ingratiate him. In one scene Alta wishes to express her gratitude for his promise of a new dress, and she gives him a hug. Though he does not hug back, she still smiles through and after the expression. Had he been less anthropometric, she would have had to express her thanks in some other way that was less pleasant to her.

Robbie warms the coffee for Alta and Farman.

In addition to being physically suited for human interaction, he is quite socially aware and able to anticipate basic human needs. In one scene, as Lt. Farman walks with Alta towards a cold pot of coffee, without having been asked, Robbie reaches down to press a button that warms the coffee by the time the two of them arrive. He also knows to leave immediately afterwards to give the two some privacy.

Despite these human-like qualities, some of his inhuman qualities make him useful, too. He is shown to be incredibly strong. He is tireless. He can synthesize any material he “tastes.”

With eyes behind his head, Robbie shoos a pesky monkey.

He even has “eyes in the back of his head,” or a 360-degree field of vision for surveillance of his surroundings. In one charming scene he combines this observation with small nonlethal lasers to shoo away a pesky monkey trying to steal fruit behind his back.

Morbius shows Robbie’’s “sub-electronic dilemma” when asked to harm a human.

Addressing safety concerns, Robbie is built to obey Asimov’’s first law of robotics. After having his creator instruct him to point a weapon at Adams, and “aim right between the eyes and fire,” Robbie’’s servos begin to click and whir noisily. His dome glows a pinkish-red as blue sparks leap across it. Morbius explains, ““He’’s helpless. Locked in a sub-electronic dilemma between my direct orders and his basic inhibitions against harming rational beings.”” When the command is canceled, the sparks stop immediately and the red fades over a few seconds.

This failsafe seems quite serious, as Dr. Morbius explains that if he were to allow the state to continue, that Robbie would “blow every circuit in his body.” Since the fault of such a state is with the one issuing the command and not Robbie, it seems a strange design. It would be like having your email server shut down because someone is trying to send an email infected with a virus. It would make much more sense for Robbie to simply disregard the instruction and politely explain why.

Microfiche reader

One other portable device that bears mention is Lt. Farman’s microfiche reader.

Farman checks Morbius’’ information.

When the officers originally learn Morbius’’ name, Farman fetches the device from a drawer. It is a small, metallic square box about the size of a pack of playing cards. He withdraws one of a set of thin transparent sheets of microfiche held in a pocket on the back, and inserts it to a slot at the top of the device. The device magnifies the contents of the sheet for the viewer, who can scroll by pulling the microfiche up and down. The particular microfiche displays all of the manifest information from the Bellerophon expedition, which Farman uses to verify Morbius’ information.

Farman looks for Julia Marsin on the Bellerephon’s manifest.

Farman uses an even smaller version of this device in the field, which consists of a small, lipstick-sized cylinder with a slit, through which he passes the same film to check for a “Mrs. Morbius.”

Though this seems like miniaturization that is far ahead of its time, microforms and optical magnification had been around and used to compactly store data since the mid 1800s. This device is an extension of these optical concepts, rather than modern digital media which only reached similar portable sizes in the early 2000s.

Military communication

All telecommunications in the film are based on either a public address or a two-way radio metaphor.

Commander Adams addresses the crew.

To address the crew from inside the ship, Commander Adams grabs the microphone from its holder on the wall. Its long handle makes it easy to grab. By speaking into the lit, transparent circle mounted to one end, his voice is automatically broadcast across the ship.

Commander Adams lets Chief Quinn know he’s in command of the ship.

Quinn listens for incoming signals.

The two-way radio on his belt is routed through the communications officer back at the ship. To use it, he unclips the small cylindrical microphone from its clip, flips a small switch at the base of the box, and pulls the microphone on its tether close to his mouth to speak. When the device is active, a small array of lights on the box illuminates.

Confirming their safety by camera, Chief Quinn gets an eyeful of Alta.

The microphone also has a video camera within it. When Chief Quinn asks Commander Adams to “activate the viewer,” he does so by turning the device such that its small end faces outwards, at which time it acts as a camera, sending a video signal back to the ship, to be viewed on the “view plate.”

The Viewplate is used frequently to see outside the ship.

Altair IV looms within view.

The Viewplate is a large video screen with rounded edges that is mounted to a wall off the bridge. To the left of it three analog gauges are arranged in a column, above two lights and a stack of sliders. These are not used during the film.

Commander Adams engages the Viewplate to look for Altair IV.

The Viewplate is controlled by a wall mounted panel with a very curious placement. When Commander Adams rushes to adjust it, he steps to the panel and adjusts a few horizontal sliders, while craning around a cowling station to see if his tweaks are having the desired effect. When he’’s fairly sure it’’s correct, he has to step away from the panel to get a better view and make sure. There is no excuse for this poor placement.

Amazon’s stock is out

A friend pointed out that as of today (September 16), Amazon’s out of stock on the book. Don’t worry, though. For new and relatively-unknown authors, they only order very small amounts for their stock. They’ll be ordering more soon I’m sure, but in the meantime, the publisher is a more reliable source. Just head to and look to the right side of the screen for the order buttons.

Military navigation

The C-57D is a military vessel with much of its technology feeling like that of a naval vessel.

Lt. Farman navigates the ship towards Altair.

The navigator, called an astrogator, sits at a station on the bridge facing a large armillary. He has a binocular scope into which he can peer to see outside the ship. Within easy reach to the left is a table-top panel of concentrically arranged buttons. To his right is a similar panel. Directly in front of him, beyond the scope, is a massive armillary that is the centerpiece of the bridge.

A model of United Planets Cruiser C-57D sits at the center of the ship’s armillary.

A model of the C-57D sits at the center of a transparent globe, which rotates in turn inside of another transparent globe. The surface of the interior globe is detailed with a graduated ring around its equator, semi-meridians extending from the poles, and a number of other colorful graduations. The outer, stationary globe has markings on the surface, which seem to describe stars and major constellations as dots and lines.

The utility of the armillary is somewhat questionable. From a relatively fixed position like the Earth, the celestial sphere doesn’t change. But while astronavigating, the celestial sphere would change. Even though Altair is a relatively close to Earth, the change in position of the stars on the celestial sphere would likely be significant to correct positioning. So, for this to be useful, the markings on the outer sphere should be dynamic. Of course in the short sequence we see the armillary in use, we would not see the markings change, but there are no visual cues that it is dynamic in this way.

Additionally it should be noted that the biggest and most important things with which Lt. Farman would be concerned, i.e. the star Altair and planet Altair IV, are not represented in the display at all and represents a major failing of the design.

The crew makes it safely through decelleration.

One of the movie’’s technology conceits is that deceleration from light speed is a shaky business. To protect the crew during this phase of travel, they stand atop deceleration stations. These small cylindrical pedestals have matching extensions from the ceiling that look vaguely like circular ventilation grills. Ten seconds before deceleration, the lights dim, a beeper sounds ten times, and the crew members step onto the pedestals. They fade from view in a beam of fuzzy aquamarine light. They fade back into view as the blue light disappears. During the period when the crew has passed from view, one would expect the ship to be shaking violently as discussed, but this doesn’’t happen. Nonetheless, as the crew steps out of the station, a few are holding their necks as if in pain.

Military defense

To defend themselves from the monster, the crew erects a defensive perimeter with terrifyingly inadequate affordance. It consists of roughly meter-high posts with eight edge-lit transparent triangles jutting out of opposite sides. When solid matter passes between any two posts, it is dealt a massive jolt of electricity. While useful, perhaps, to trap an invisible, animal-minded monster, the lack of any visual affordance to this effect seems stupidly dangerous to innocent animals and humans that might unknowingly step across its fatal path.

The bosun tests the defensive perimeter.

Forbidden Planet: Overview

Release Date: 15 March 1956, USA

The crew of the military vessel C-57D travels to planet Altair to investigate the fate of the Bellerophon expedition. Ignoring warnings radioed from the surface, they land on the surface where officers Adams, Farman, and Doc meet Morbius, his daughter Altaira (aka “Alta”), and his domestic servant robot Robbie. The same invisible terror that had killed every other member of the expedition begins to threaten the military crew. Adams and Doc confront Morbius, only to learn that he has been hiding the secrets of an ancient alien technology beneath the surface of the planet. They discover that it is Morbius’’ use of this Krell technology that created and controls the monster. Morbius faces the monster and dies, but not before instructing Commander Adams to destroy the planet and save humanity from the temptation of using it and repeating his mistake.
