About AIBO
The AIBO is a robotic dog manufactured by the Japanese company, Sony. The name AIBO is an acronym for Artificial Intelligence roBOT, but in Japanese, the word AIBO also means "partner" or "companion." The first model was the ERS-110, released in 1999. The model we will be working with is the most recent, the ERS-7 running Mind 3 software.
The AIBO is able to adapt and learn from interaction with people and its environment. It is equipped with a number of sensors for detecting distance, motion, and touch. AIBO also has face and voice recognition and can respond to several different voice commands.
Sony describes the AIBO as an autonomous entertainment robot. Wikipedia defines an autonous robot as a robot which can perform desired tasks in unstructured environments without continuous human guidance. Many kinds of robots are autonomous to some degree, but different robots can be autonomous in different ways. For example, the AIBO monitor's its own battery level, and returns to its docking station to recharge when its battery level drops too low.
According to Wikipedia, a fully autonomous robot in the real world has the ability to:
- Gain information about the environment.
- Work for months or years without human intervention.
- Travel from point A to point B, without human navigation assistance.
- Avoid situations that are harmful to people, property or itself
- Repair itself without outside assistance.
A robot may also be able to learn autonomously. Autonomous learning includes the ability to:
- Learn or gain new capabilities without outside assistance.
- Adjust strategies based on the surroundings.
- Adapt to surroundings without outside assistance.
Of course, autonomous robots still require regular maintenance, as do other machines.... Right now, two of our AIBOs must go to Sony's AIBO hospital.

IMPORTANT NOTE:
The AIBO is a very expensive and delicate piece of equipment. Treat it with the utmost care. The AIBO Handler must always have AIBO lay down or pick it up before turning the power off. When the power is turned off, AIBO's joints go limp and if it is standing at the time, it will fall and might be damaged.
Your Task
In this assignment, you will become familiar with the AIBO and many of the features that it possesses.The AIBO Handler should place the AIBO in a lying position on the floor and turn it on by pressing the button on its back. The startup procedure will take a few moments as AIBO repositions its joints.
The AIBO is designed to be an interactive autonomous robot which has a variety of sensors and can communicate with humans in several ways.
Sight
The AIBO is designed to recognize and respond to human faces. When it recognizes a face, it will display a triangular group of a set of 3 LEDs on its face. See if you can get AIBO to recognize one of your faces.
The AIBO can also recognize its toys, the pink ball and the AIBone. If the programmer will move one of these very slowly in front of the AIBO's face, it should follow the movement.
Touch
The AIBO has a variety of sensors, which with the permission of the AIBO Handler can be lightly stroked. With the permission of the AIBO handler, one by one, each team member may gently stroke one of the sets of sensors located on the head, chin, and back.Sound (Speaking to the AIBO)
The AIBO Trainer can try calling out the following voice commands to see how AIBO responds. The AIBO Trainer must be patient, giving each command one at a time and then waiting, giving the AIBO amble time to respond. Note that the AIBO's mood can affect how it responds to commands. If AIBO isn't happy, it may not respond at all. The AIBO will be much happier once it has been given a name and some owners.
- "Hello, AIBO!"
- "Good Morning!"
- "How are you?"
- "Are you sleepy?"
- "Are you hungry?"
- "Good AIBO!"
- "Lay down"
- "Stand up"
- "Walk around"
- "Let's dance"
- "Talk to your friend"
- "What time is it?"
- "Take a picture"
- "What is your name?"
- "What is your owner's name?"
Each AIBO also has a toy bone and ball that it can interact with. For example the programmer can place the pink ball in front of AIBO and the AIBO Trainer can say, "Find your ball." AIBO will scan the area for the pink ball and "play" with it once it is found. AIBO can also remember the location of the ball, but if you move the AIBO, it will become disoriented. The AIBO Handler can pick up AIBO, sit it down facing away from the ball and the AIBO Trainer can then ask it, "Where's your ball?"
Each AIBO learns his or her name. The AIBO Trainer can try calling the name which have been given to the AIBO.
There are many other voice questions and/or commands that the AIBO recognizes--ask your instructor if you want to try more of them.In addition to understanding communication from humans, the AIBO attempts to communicate back through a variety of modes, the most obvious of which is speaking.
Lights and Mode Indicators (Communication from the AIBO)
The AIBO has a large number of LEDs on its face which can be used to communicate with humans. Different patterns appear for each emotional and/or physical condition as follows:
The AIBO also has Back-lights on its back which indicate mood and condition as follows:
The AIBO has larger lights around its ears which are called mode indicators.
In addition to these non-verbal modes of communication, the AIBO has been programmed to demonstrate emotions through movement.
Your Lab Report
This lab report must be completed INDIVIDUALLY.- The lab number: Lab 20
- Your name
- The name of the AIBO you worked with: for this lab.
- Sight: Describe how well the AIBO responded to visual communication. Did it appear to recognize faces? Was it able to see its pink ball and/or AIBOne?
- Touch: Describe how well the AIBO responded to touch communications. Did it respond when you "pet" it?
- Sound: Describe how well the AIBO responded to verbal communications. Did it respond to the commands?
- Responses: Did the AIBO respond to its name? Describe any non-verbal communication from the AIBO which you recognized. Did you recognize any LED patterns? Did you find its motion to be emotionally expressive?
- Applicability: Although the AIBO was designed as a toy, many of its features could be used in more practical robotic applications. Choose TWO of the following features, describe in a few sentences of detail a practical application of robotics where this feature could be useful and how it would be useful there. Use each practical application only once.
- The AIBO has a video camera in its nose.
- The AIBO has several touch sensors --one on each foot, three on its back, one on the top of its head, and one on its chin.
- The AIBO has a distance sensor in its nose.
- The AIBO has built-in edge detection to detect edges such as a table edge (Do not trust this feature to keep the AIBO on a table!)
- The AIBO has built-in obstacle avoidance software (Do not trust this feature either!)
- The AIBO has face-recognition software and will recognize human faces.
- The AIBO can store information about certain special faces, so it can recognize it's owner's face.
- The AIBO has a microphone and voice-recognition software and will recognize vocal commands.
- The AIBO can store information about certain special voices, so it can recognize it's owner's voice.
- The AIBO has a speaker and can respond to humans vocally.
- The AIBO has adaptive software, so can learn about its environment, including its owner's preferences.
- Active/Passive Sensor Classification: In our text, we learned the difference between active and passive sensors. Briefly explain this difference and choose one of each different sensor type on the AIBO to classify as active or passive.
- Simple/Complex Sensor Classification: In our text, we learned the difference between simple and complex sensors. Briefly explain this difference and choose one of each different sensor type on the AIBO to classify as simple or complex.
- Autonomy: The AIBO is designed to be an autonomous robot, which is not true of the Lego Mindstorms. Briefly describe some of the most important features you believe contribute to this autonomy.
- Lab comments and Suggestions: Write a paragraph that summarizes yourreaction to RoboLab and to this lab. If there are any problems you encountered or any questions that remain, please ask! Also, be sure to include any suggestions you have for how this lab could be improved.
