Anthropomorphic Robots

Could robot’s ever duplicate humans? Since humans first conceptualised robots we have aspired to give robots human form and abilities. Science fiction has long represented humanoid robots in film and literature. Even our children’s robotic toys aspire to human form – eg Robosapien - A fusion of technology & personality

Even our pets haven’t been left out of the robotic picture- eg Sony Aibo, roboraptor etc. Questions: What are the advantages/ disadvantages of a robotic pet over a biologically live pet? Why are humanoid robots so difficult to make? Why don’t we have 2 legged ambulatory robots everywhere by now?

Could robots ever replicate human beings

physical , emotional and reasoning abilities?

Could technology improve on

humans?

What facets could we improve, delete,

modify?

What makes us human?

What advantages do robots have over human beings?

Is the ability to have emotional responses an advantage or disadvantage.

What is a 6th sense?

Could this pose dangers to human beings?

Isaac Asimov in his 1942 short story “Runaround”, c reated these laws for robots A robot may not injure a human being or, through inaction, allow a human being to come to harm. A robot must obey orders given it by human beings except where such orders would conflict with the First Law. A robot must protect its own existence as long as such protection does not conflict with the First or Second Law. Would these laws protect us? How would a robot process the word harm? Can we quantify “harm” in such a way that we could program a “harm” response in a robot?

LET’S CONCENTRATE ON EMOTIONS

Question - Is personality a function of emotions? Question - Does our physiology affect our personality?

“Benedict de Spinoza in the 17th century described emotions as bodily changes that result in the amplification or attenuation of action and as processes that can facilitate or impede action. For Spinoza, emotion also included the ideas, or mental representations, of the bodily changes in emotion.

Today, there continue to be researchers who define emotions in different ways. At the extremes,

emotions can be seen as biological responses to situations over which we have little control. Plutchiks

theory of emotions is one that stems from the biological perspective. At the other extreme, there are

psychologists who define emotions more by the conscious experience rather than by the biological response. One of these is Schachter.

Most researchers today accept that emotions operate on a number of levels. A common view is that emotions consist of:”

Subjective

feeling That is how the individual interprets what they are feeling at any point. These are

inner personal experiences. How one individual interprets "being in love" will often be

different to the next person. Subjective feelings in response to an emotion cannot be

readily observed. As a result, the self-report method is often used to collect data in

this area. Expressive

behaviour This refers to the outward signs that an emotion is being experienced. Such

behaviour can be intentional or unintentional and includes facial expressions as well

as body language. Physiological

responses This involves bodily changes which occur when we experience an emotion. This

involves the operation of the brain as well as the Autonomic Nervous system and

research by Candace Pert suggests that it also involves the cells in our body. It is

often our awareness of the arousal that makes us suddenly aware that we are

experiencing an emotion.

Which of these could make a robot more effective?

Which of these could be ignored in robot design?

Why would we program these responses?

The practical element of this section of the unit w ill focus on creating expressive behaviour, primarily of the fac e, in LEGO

robots within the limitations of our students abil ities


The simplest starting point is looking at cartooning. Students should research the way cartoonists simplify the basic expressions of the human face to a universally recognised expression. The idea is to refine these facial expressions to a minimum. Direct the students to concentrate on 3 features – the eyes, eyebrows and mouth. By using a combination of LEGO building elements and non LEGO materials such as sausage balloons, LED’s and plastics it is possible to create a basic robotic face that is able to exhibit simple expressions. Some simple robo-toys show basic “emotions” using coloured LED’s

Bottom left pictures a basic LEGO face that is programmed to show simple facial expressions.


The following is a simplified form created from LEGO and other materials that is able to show simple facial expressions: Scientists have already made progress with robots that can exhibit basic facial expressions NEXI ZENO

At right – Ever2 The NXT Robot has the ability to also show simple graphics on the LCD panel as well as play sounds. It is therefore well within your students capabilities to program their robot to respond to tone of voice with a graphic and sound effect Please refer to these documents/ programs for further information Creating Graphics for NXT Creating sounds for NXT NXT sound and graphics samples

“should we create such a machine, if the possibility becomes available to us. Are there uses for such a

machine that could not be satisfied by a complex automaton? Is there anything about real emotional

response that would be necessary for a machine to operate autonomously, and still interact with human

beings? What are the dangers? What are the ethical ramifications?

Simulation and Replication

By simulation, I mean a robot that is functionally the same as a human in its behavior, but is still to be

considered simply a machine. A robot that will react to inputs from its environment exactly the same as a

person would, but is not itself a person, only a clever imitation of one. By replication, I mean a robot that

actually is a person, not just an imitation of one. A “strong AI” intelligence that has a real, conscious mind,

and emotions, just like a human being.

Both of these arguments can be looked upon as controversial, in regards to the argument over

whether or not a replication AI can actually be built. Few would argue that an excellent simulation of a

human would not eventually be built. Sooner or later, as technology advances, it is highly likely a

simulation that can pass for human will be devised. What seems to be controversial about this idea of

simulation is that some in the field of AI feel that there would be no difference between a perfect simulation

of a person and a replication of a person. That is, a functionally perfect simulation would be a replication.

This seems to me somewhat of a behaviorist view, one in which only the inputs and outputs are important,

not the mysterious inner workings of the person or the machine.

“Folk” psychologists, as well as philosophers, believe that computers lack the ability to reproduce

some fundamental properties of the mind, such as semantic content, or intentionality


Emotional Response and Practicality

Before considering whether or not robots should have emotions, I think it will be useful to take a

cursory look at least into why human beings have emotions. I think there are a couple of ways of looking at

this. First of all, human emotions are integral to our lives, the way we define ourselves as persons. Our

personalities are closely connected and determined by the things we love and hate, our fears and our search

for happiness. We value our emotions as intrinsic to our beings, even when they cause us pain, fear, or

anxiety. That said, another way of considering emotions is to ask how they are functionally beneficial to us.

It is not impossible to imagine human beings without emotions, cold calculating beings still fully capable of

forming communities, procreating, and providing for their own survival.

The question is, do emotions serve a functional purpose that cannot be satisfied by a purely reason-

based process?

Philosophical psychologist Patricia S Greenspan describes emotions as “propositional feelings”, with

important differences from more rational beliefs and judgments (Emotions & Reasons, p. 4):

(1) Although its appropriateness may be explained in terms of belief warrant, the evaluative component of

emotions need not rest on reasons adequate for belief.

(2) The affective component of emotions gives them a special role to play in rational motivation, as “extrajudgmental”

reasons for action.

Because of this, imagination and intuition can play a role in our actions, as these “extrajudgmental”

emotions allow them as reasons for action. Greenspan also describes emotions as resistant to direct rational

control, saying “..it will assume resistance to direct control, of the sort we have over action. In this respect

and others emotion seems to stand in between action and belief, exhibiting some features of both

categories.” (p. 10)

From this I think we can determine some practical uses for human beings to have emotions.

Emotions may help us to take action in situations where we may feel something that we can’t justify through

conscious rational beliefs .


The Danger of Emotion

After looking at some practical applications for emotion, some of the dangers inherent in emotion

should become readily apparent. Emotions can and often do lead people to take unwarranted action. A

perfect example of this is jealousy. Science fiction abounds with stories warning of the dangers of an

emotional robot. For instance, HAL 9000, the conscious computer in Arthur C Clarke’s book 2001: A Space

Odyssey becomes paranoid, afraid for his life, leading him to murder the crew of the ship he controls.

Another science fiction author, Isaac Asimov, envisioned such robots being kept in check by his famous

Three Laws of Robotics, central beliefs programmed into the robot to prevent it from harming humans.

However, human emotions have the ability to circumvent even our most basic beliefs (consider the jealous

husband), so one could easily argue that an emotional robot might ignore such laws when in a highly

emotional state. .

Societal Integration

We are all integrated into a society, which teaches us morals, ethics, and most importantly here, limits on the

actions we take to express our emotions. The dangerous killer robots of science fiction tend to exist in a

social vacuum, removed from human society and without a society of their own. A possible solution to the

unpredictability of an emotional robot is social integration. Humanoid robots might be taught to feel as that

the robots we interacted with did not really feel, I think most people would still be happy with simulations as

companions. Only building simulations would eliminate all the risks of an emotional robot deciding to harm

a human, and we still haven’t discussed any practical reason to have a true replication.

Emotional robots learn from people Making robots that interact with people emotionally is the goal of a European project led by British scientists.

Feelix Growing is a research project involving six countries, and 25 roboticists, developmental psychologists and neuroscientists.

Co-ordinator Dr Lola Canamero said the aim was to build robots that "learn from humans and respond in a socially and emotionally appropriate manner".

The 2.3m euros scheme will last for three years.

"The human emotional world is very complex but we respond to simple cues, things we don't notice or we don't pay attention to, such as how someone moves," said Dr Canamero, who is based at the University of Hertfordshire.

Sensory input

The project involves building a series of robots that can take sensory input from the humans they are interacting with and then adapt their behaviour accordingly.

Dr Canamero likens the robots to babies that learn their behaviour from the patterns of movement and emotional state of the world around them.

The robots themselves are simple machines - and in some cases they are off-the-shelf machines. The most interesting aspect of the project is the software.

Dr Canamero said: "We will use very simple robots as the hardware, and for some of the machines we will build expressive heads ourselves.

"We are most interested in programming and developing behavioural capabilities, particularly in social and emotional interactions with humans."

The robots will learn from the feedback they receive from humans.

"It's mostly behavioural and contact feedback.

"Tactile feedback and emotional feedback through positive reinforcement, such as kind words, nice behaviour or helping the robot do something if it is stuck."

The university's partners are building different robots focusing on different emotional interactions.

'Detect expressions'

The robots will get the feedback from simple vision cameras, audio, contact sensors, and sensors that can work out the distance between the machine and the humans.

Movie I Robot depicted emotionally complex machines


"One of the things we are going to use to detect expressions in faces and patterns in motion is a (artificial) neural network."

Artificial neural networks are being used because they are very useful for adapting to changing inputs - in this case detecting patterns in behaviour, voice, movement etc.

"Neural networks learn patterns from examples of observation," said Dr Canamero.

One of the areas the robots will be learning from is human movement.

"Motion tells you a lot about your emotional state.

"The physical proximity between human and robot, and the frequency of human contact - through those things we hope to detect the emotional states we need."

The robots will not be trying to detect emotional states such as disgust but rather will focus on states such as anger, happiness, loneliness; emotions which impact on how the robot should behave.

'Imprinted behaviour'

"It is very important to detect when the human user is angry and the robot has done something wrong or if the human is lonely and the robot needs to cheer him or her up.

"We are focusing on emotions relevant to a baby robot that has to grow and help human with every day life."

One of the first robots built in the project is exhibiting imprinted behaviour - which is found among birds and some mammals when born.

"They get attached to the first object they see when born.

"It is usually the mother and that's what makes them follow the mother around.

"We have a prototype of a robot that follows people around and can adapt to the way humans interact with it.

"It follows closer or further away depending on how the human feels about it."

Dr Canamero says robots that can adapt to people's behaviours are needed if the machines are to play a part in human society.

At the end of the project two robots will be built which integrate the different aspects of the machines being developed across Europe.

The other partners in this project are the Centre National de la Recherche Scientifique, Universite de Cergy Pontoise, Ecole Polytechnique Federale de Lausanne, University of Portsmouth, Institute of Communication and Computer Systems, Greece, Entertainment Robotics, Denmark and SAS Aldebaran Robotics, France.

“The most advanced robots in the very fine movie I, Robot had the ability to interpret the emotions of the human beings around them. They did it by analyzing the stress patterns in the voices they heard. In phrasing it just that way, the film pays homage to an earlier computer who did just the same thing - the HAL 9000 computer from 2001: A Space Odyssey.

Today, Affective Media Limited in Scotland is working to help computers better understand people in various stages of emotional stress. Affective Media even has an online demo with an animated character named Tetchy the Turtle, who accepts voice samples and analyzes them. “

This excerpt taken from : http://www.slipperybrick.com/2008/04/mit%E2%80%99s-nexi-the-overly-emotional-robot/

“MIT thinks that the world needs an emo robot. That’s why they created this next-generation tiny humanoid robot called Nexi. It’s an ‘emotional robot’ designed by roboticist Cynthia Breazeal’s group at the MIT Media Lab. It’s known as an MDS (Mobile/Dexterous/Social) robot, which basically means it can move it’s body, hands, and face in a way that suggests human emotions. Its arms, wrists, and hands are fully adaptable to clutch and raise up to 10 pounds and by the looks of it this thing is probably a cutter too.

It possesses changeable features including eyes, eyebrows, eyelids, and mouth movement. It creeps us out in a whole new cartoon way. It also moves on a pair of animatedly self-balancing wheels. So, if you hurt it’s feelings, it will have no problem chasing you down and killing you.”

“Dr Christian Jones, the chief executive of Affective Media, puts it this way:

"When you are depressed or sad, the pitch of your voice drops and your speech slows down. When you are angry, the pitch rises and the volume of your voice goes up. We betray our emotions as we talk in dozens of subtle ways. Our recognition system uses 40 of these. It ignores the words you use, and concentrates exclusively on the sound quality of speech. It can tell your emotional state the very first time it hears your voice." http://www.technovelgy.com/ct/Science-Fiction-News.asp?NewsNum=1648


Asimo http://www.technovelgy.com/ct/Science-Fiction-News.asp?NewsNum=1658 Emotion recognition – face & sound Active Appearance Modeling is an apparently helpful technology developed to help robots identify individual human beings. Let's take a closer look at how this works.

The basic idea is to identify specific landmarks on a person's face, like the eyes, eyebrows, mouth, nose and so on. Then, a mesh can be created by connecting these landmarks. Finally, the computer is able to create a three-dimensional mesh model of an individual face.

Carnegie Mellon University researchers are pushing this idea even further. Their active appearance modeling software can identify faces that are partially occluded by objects.

1. Communicate emotionally - facial expressions, affective sound, bodily gestures. 2. Use multiple sensory modalities that are shared by humans - including vision, touch, and hearing. 3. Make something that can move around independently. 4. Have it move/experience/act through the same physical and social spaces as people do. 5. Make lots of them - and have them exhibit flocking behavior.

Basically, Mike is a robot made by Brazilian students that can express its emotions through the colors of its eyes: red is for anger, green is for happiness, and orange is for sadness. Now we only need to know how a robot can feel those emotions, but that detail will be discussed in a future post.

Mike will be presented tomorrow at the International Robotics and Artificial Intelligence Fair, taking place in SÃ£o Paulo, Brazil.

"Anthropomorphic" Robots, while Animatronic in nature, are in a category of their own, simply because they represent the highest level of expression of Animatronics from the point of view of their more fluid and human-like body motions. International Robotics was responsible for launching two Anthropomorphic Robot programs for its client Ford Motors, which have been used successfully at Auto Shows throughout the world.

The Anthropomorphic Robot offered by IRI is also in a class of its own amongst other Anthropomorphic machines, in that it is the world's first and only Robot combining a revolutionary mix of electric motors and miniature hydraulic chambers, using plain water instead of Hydraulic fluid. We call this "Aquadraulics". Read on, and you'll discover how truly revolutionary this technology is, and how much sense it makes to own or rent one. Of course, we'll give it any shape or appearance you need."
