Your View: How would you define a robot?

The word robot made its debut in 1921, in the play R.U.R. (Rossum's Universal Robots) by Karel Capek. It comes from the word "robota", a Czech term for forced labour. But definitions of what a robot actually is vary widely.

Alan Mackworth, the director of the University of British Columbia Laboratory for Computational Intelligence and president of the American Association for Artificial Intelligence, says:

"It's a machine that can sense and act and react in the world and possibly involves some reasoning for performing these actions, and it does so autonomously. By that definition a thermostat would be a robot. Though it's not 'aware' it has a goal, that awareness isn't required."

Rodney Brooks, the director of the Massachusetts Institute of Technology computer science and artificial intelligence laboratory, says:

"To me a robot is something that has some physical effect on the world, but it does it based on how it senses the world and how the world changes around it."

Gregory Dudek, the director of the Centre for Intelligent Machines at McGill University in Montreal, sets three criteria for robots.

"They have to have a way of making measurements of the world, they have to have a way of making decisions — in other words, something like a computer, you could call that thinking informally — and they have to have a way taking actions."

Joseph Engelberger has been called the father of robotics. Asked to define a robot, he once said

"I can't define a robot, but I know one when I see one."

Why are we even concerned with defining 'robot'? Given that what we traditionally consider 'robots' have all been man-made, the definition can be whatever we'd like it to be.

It is rather interesting though that the 2nd and 3rd definitions quoted in the article can both be applied to humans!

A robot is to a machine as a computer is to an electronic device; a generalization that can be programmed to perform the same specific tasks. A robot is a computer that performs physical work. A robot is God's grandchild, who He spoils with refined machine oil and drops off all hyper and ill-tempered. A robot is a mechanical mook, making mensch mendicant and milling mechanisms to manufacture more robots. Johnny Five is ALIVE!

A Robot is a machine created with the ability to reproduce human action in order to better our workforce and even family life.

Personally? I would love to have a little robot vacuum. I'd name it Kirby. I know it doesn't think or feel, but I would still find it adorable and I'd treat it well, considering it has the smarts to avoid obstacles and won't fall down stairs the way my dogs and cats always seem to do. *laughs*

Too many devices which are simply remotely operated machines are being called robots - by their makers and by the media.

A real robot must be able to function autonomously. Then the definition revolves around the complexity of functions it is capable of before it should be called a robot.

The span is from the dishwasher to (the currently fictional) Lt. Commander Data. Where should the line be drawn? I don't know!

Prof. Dudek's definition:

"They have to have a way of making measurements of the world, they have to have a way of making decisions ... and they have to have a way taking actions..."

is lacking an essential 4th element - they have to have goals, or else they cannot respond to their measurements of their environment. Presumably this would involve generic pre-programmed goals (like Asimov's Laws), the ability to acquire goals through communication with other robots and humans and ultimately, the ability to generate goals internally.

My definition of a robot is a machine that can be programmed to perform a given function or task without having to be controlled directly.

A robot doesn't need to possess intelligence, but does need a basic set of instructions that enable it to function in the environment it is placed in.

On a side note, the concept of artificial intelligence is fascinating but I hope emotion can/will never be re-created in a machine. That would just be disastrous.

As a person that has worked with industrial robots for over 15 years, I term a robot as a device that does exactly what we tell it to do, when we tell it to do it. If a robot is told to move to a new location it will.

Robots are now coming into the household to vacuum and cut the grass but still no robot to serve me a cold beer after coming home from working on robots all day! Will that be invented in North America or oversea's?

A "Robot" is a mechanical or organic semi/self controlled machine that perform physical tasks from which humans are capable of, and that it must look somewhat intelligent in the way those movements are performed, and that it must have some of the human body shape to it.

When a "Robot" resemble a human, and can mimic the human behavior, and it's look is organic, it will then be called "Humanoid".

For example...

A microwave oven does not fit this criteria. It looks stupid, does not move, and performs tasks no human can perform.

The Mars rover fit this criteria because it looks intelligent by avoiding obstacles, and can perform tasks that humans are also capable of performing.

Car manufacture robots also fit this criteria because they have arms similar to that of humans, and can pickup/drop and manipulate objects like humans do.

A desktop computer does not fit this criteria because it does not move, and performs no physical tasks whatsoever beside spinning disks and fans, which no human can perform.

"Data" in Star Trek is "Humanoid", not "Robot". We have yet to have a real example as no "Humanoid" has ever been physically created.

Intelligence does not make anything a "Robot", whereas humanoid behavior will.

A microwave is not programmable in three or more axes and it is obviously not a manipulator. If your microwave fits that bill as your article suggests - it must be one horrifyingly over-engineered appliance.

Is the term robot too broad? - What about the term vehicle? A motorcycle, a car, and a snowmobile are all vehicles - but a motorcycle is not a car, is not a snowmobile. Is a rollerskate a vehicle? A running-shoe?

As there are different types of vehicles, there are different types of robots. Like the shoe or skate above, there are also things where you would be making a stretch call a robot, and I think most home appliances fall into this category.

There is also alot of media sensationalism and marketing hype. Marketing a product as vacuum ROBOT sounds alot more exciting then simply calling it an "automatic vacuum cleaner". Although I can understand considering it to be a robot.

Is a string puppet a robot? What if one pre-records the movements of the puppet-master and reproduces them electro-mechanically? You end up with what is today called an animatronic. It could be considered autonomous on a very basic level. The old mechanical "player piano" and the wind-up music-box also fall into this category. How are the Japanese receptionist "actroids" any different from animatronics? The entire functionality of the physical animatronic component is purely superfluous.

There are also upper limits. The humanoid type robots are fine to call robots, (Asimo is a good example) but as they become more human-like in appearance, and get better at mimicking intelligence we may prefer to switch to terms like "android", to distinguish them from "robots".

Autonomy with today's software technology has a very limited scope It does not even remotely qualify as thought, and BARELY as "a form of thought". People seem a bit confused between science fiction and modern technology. It is very important to understand - NEVER to forget the "A" in "AI".

A robot is an object containing a chipset and a mechanism which when combined allow the machine to interact with its surronding. note: a camera allows this.) The chip allows calculations from preprogrammed functions to be performed and the mechanism allows those functions to be pratical in a dynamic world.

Here is my definition of a Robot:
A programmable machine that interacts with the physical world autonomously and includes the following features:
* Performs physical tasks autonomously without having every action pre-determined;
* Can sense and react to its environment;
* Can achieve a goal in more than one way autonomously;
* Can move itself, part of itself and/or another object in the physical world;
* After it has been programmed and has started working towards its goal, it can modify its own behaviour and actions in response to unpredictable stimuli from its environment.
* Is able to make decisions for its self using the following constructs:
- Do or test for something a set number of times
- Do or test for something while a certain condition exists or until a certain condition exists
- Choose between a minimum of 3 different courses of action based on a variable

The simplest definition of a Robot is a machine that interacts with the surrounding environment, which means it sense and act based on the data collected by the sensors. So a machine to be called a robot it has to have three parts: sensors, processing unit, feedback

A robot is an artificial system that acts autonomously in the real world for the purpose of achieving goals safely, where its decisions to act are based on its perception of the world and where its goals are defined as desired world states.

Notes:

1. "world state" :- The way everything around the world is right at this instant in time. The moment the next event occurs, the state has changed. You can state a goal in terms of the state you would like the world to have. While this is obviously too inclusive, in practice, it's sufficient to restrict this description of state to what kind of goal you're interested in describing. So, for example, suppose a door is closed and you want to open it: here, the state is that of the door and the goal state is "the door is open". Another example: suppose you're in St. John's and you want to go to Vancouver. The state is that of your position, and your goal state is "my position is St. John's, NFLD". States even let us describe the effect of actions, so suppose you say that your goal is walk around the block for your health. The state is that of what distance you have walked and the goal state is: "the distance travelled is that of the perimeter of the block".

2. "perception", "act". Perception doesn't just mean "sense". Perception is the process of using sensor data to estimate the state of the world sufficient for it to act towards achieving its goals. For a thermostat, the piece of metal that expands or contracts does indeed perceive the temperature sufficiently to act, and in fact the change in the metal change is exactly the action required to throw a switch. The goal state, here, is expressed as a temperature.

I think this definition includes thermostats, Breitenberg machines, etc., and it successfully excludes washing machines (unless they have dirt sensors), microwave ovens, cars (unless it has cruise control or it's that new Lexus that helps you parallel park :) ).

Reply; I do beleive this feat has been acheive through camera's, microphones and speakers.

Robot,
A materialistic object created using wires, circuit boards and memory chips to make a humans life safer and more convienent, or simply for ones amusement/ entertainment. These objects can take pratically any shape or form, weigh a few ounces or tonnes, as tall as a few inches or six feet. They can often be controlled through a computer, or have a memory chip set in them to do whatever that is required of them. A Robots AI (Artificial intelligence) hasn't been reasearched enough to fully function and operate on their own. Their tasks are limited are as too what was added on to them, or how they were built; similar to humans. More times often then not, a robots 'blood and guts' which happens to be circuits wires and eletcricity.

A robot is defined as a person whose work or activities are mechanical. For robots to move, usually they have wheels or tractors. Most robot builders use legs although wheels are more convenient. Some robots are controlled by remote controls which means people are controlling it. People wonder if robots will one day take over the world but in my opinion, I do not think they will have enough exactness or common sense to do this. Although people are still experimenting with robots today, they will improve as the years go on.

The International Organization for Standardization also has a definition. Under ISO 8373, a robot is: "An automatically controlled, reprogrammable, multi-purpose manipulator programmable in three or more axes, which may be either fixed in place or mobile for use in industrial automation applications."

I agree with the International Organization for Standirization. I believe a robot is a device that can serve multiple purposes while being controled automatically. Something as simple as the timer on your microwave. Robots are fascinating creations and it will be awesome to see scientists achieve new and improved ones in the future.

A Robot is a machine that is prgrammed to do something, it does not "think" on it'own. in the future if a robot is somehow programmed to think then they still wouldn't be thinking automatically or on it's own they would be programmed to do so. research groups and all the people who study the human body still find some functions as a mystery. when we understand and can emulate a human body and all of the vital organs then i guess the result would be the robot we all see in hollywood. the thing is a definition for robot all depends on the person's opinion or perception of machinery. my definition would be any machine that can take in their environment and react to it as if it had a brain.

A robot is a machine that can be programmed and reprogrammed. If a machine is programmed to clean a house, it should also be able to be programmed to do something else or to be unprogrammed. I do not think that a microwave or a dishwasher is a robot because it is not allowed to sense its surroundings.
