How the Aibo Donor Program Works

As fellow Aibo owners we all know how difficult it is when things go wrong and our lithium ion powered pals need repair.

Whilst this is almost always possible, it can get expensive if parts are required and the repairs needed are extensive.  It is for this reason that we have launched the Aibo Donor Program.

You see, we believe that every Aibo deserves the right to live on through repair but the sad fact of life is that not every owner can afford this.  After all some of us have had our Aibo's for 20 years now

and personal circumstances change.  Some were given as generous gifts and some were even as prizes in competitions but what this means is that although we have a high tech powered pal to keep

us company we can't always afford to keep them fit and healthy.

That's where the donor program comes in.  We accept Aibo's in all types of condition or age from generous owners who want their pals to live on in others when they reach their end of life.

We then respectfully and carefully asses how these donated Aibo's can benefit others and then store them accordingly.  We will also provide the original owners with a certificate of donation showing the date, name and model and serial number details of their donation

as these details are added onto our Aibo donation register.  The original owners will then be notified as and when their pal has helped others to keep going.  This allows the original owners to take some solace in the fact that they are helping others

and that their own powered pal is living on within another.  According to our strict privacy policy we will not divulge any owner information unless given permission to do so and this is all confirmed upon donation.

Should anyone have any questions about the Aibo Donor program we are always happy to help by text, email, phone or email and we can answer any question you may have.



The ERS-220 was released by Sony in November 2001.

The ERS-220 was designed by Japanese designer, artist, and producer Shoji Kawamori. Notably, he also created the anime series Macross and worked on mechanical design for Ghost in the Shell.
Unlike other AIBO models, the ERS-220 was not designed to appear at all organic but instead took a directly mecha-inspired approach.



The hardware of the ERS-220 is identical to the ERS-210 with the exclusion of four degrees of freedom (no moving "tail" module or articulated ears). A variety of LEDs were added that were not present on the ERS-210.

Leg: 16 degrees of freedom per leg
(20 degrees of freedom in total)
Power consumption Approx 9 W (in normal mode)



Along with ERS-210's, the ERS-220 was released as a Supercore AIBO. However, the ERS-220 was not utilized in RoboCup competition. Worth noting is the ERS-220's dependence on OPEN-R 1.1.3, which shipped out-of-the box with Supercore modules but not the initial releases of 2x0 cores.

Special Editions

The ERS-220 was also released as the Transformation Kit, or ERS-220E1 (referred to as ERS-220/TK frequently by the community.) The kit included the ERS-220's modular components (head, tail, legs) without a core as to offer a way for ERS-210 owners to update, if desired, to the newer AIBO.

The third generation of original AIBOs, the ERS-7 was the most advanced AIBO of its era.

"AIBO" [ERS-110] is an autonomous robot that acts both in response to external stimuli and according to its own judgement. "AIBO" can express various emotions, grow through learning, and communicate with human beings to bring an entirely new form of entertainment into the home.

Not only is "AIBO" capable of four-legged locomotion by virtue of the 3 degrees-of-freedom in each of its legs, but it can also perform other complex movements using its mouth, tail, and head, which have 1, 2, and 3 degrees-of freedom, respectively. "AIBO" incorporates various sensors and autonomous programs that enable it to behave like a living creature, reacting to external stimuli and acting on its own judgement. "AIBO's" capacity for learning and growth is based on state-of-the-art artificial intelligence technology that shapes the robot's behavior and response as a result of repeated communication with the user and interaction with the external environment.

The "AIBO Performer Kit" [ERF-510] includes an easy-to-use motion editor tool that allows users to create original motions for "AIBO". A graphical user interface that makes it simple to create motion programs for "AIBO" on a personal computer.

Main Features of "AIBO" [ERS-110]

1. Autonomous Judgement and Response
"AIBO" incorporates emotions such as happiness and anger and instincts such as the need for companionship. It operates autonomously in response to external stimuli and its own temperament and express emotions as well. "AIBO" is equipped with adaptive learning and growth capabilities that allow each unit to develop a unique personality including behavior shaped by the praise and scolding of its owner. Moreover, "AIBO" features 'game' and 'performance' modes that allow the user to give instructions to the robot using a tone-based remote control unit called the "Sound Commander." Users can also create motion data using a PC-based motion editor tool, which is sold separately, for the performance mode.

2. Smooth Movement with 18 Degrees-of-Freedom
A total of 18 degrees-of-freedom (1 for mouth, 2 for tail, 3 for head, and 3 for each leg) allow "AIBO" to walk smoothly on four legs as well as perform other complex motions.

3. Memory Stick for Easy Replacement of Programs
A pre-recorded 8MB "Memory Stick" comes as an accessory to "AIBO". It is used to store the software modules that control "AIBO's" movements and data that is generated during the learning process. "Memory Stick" makes it easy for users to insert new software modules into "AIBO," including original motion programs created by the user using the motion editor (sold separately).

4. Modular Software Based on the OPEN-R Architecture
"AIBO" employs modular software based on the OPEN-R architecture to facilitate the quick and easy addition and/or replacement of individual software modules.

5. Advanced Sensors Provide Increased Autonomy
The use of sensors, microphones, and speakers that roughly correspond to the sensory organs of a living creature make it possible for "AIBO" to communicate and react to external stimuli with a high degree of autonomy.

Touch Sensor : For recognizing tactile stimulation like being pet or hit
Color CCD Camera : For detecting the shapes and colors of objects when approaching or avoiding them
Range Finder : For detecting the distance to objects
LED Lamps : For expressing happiness (green) and anger (red)
Mini Stereo Microphone : For detecting the direction of a sound source and hearing sound from the Sound Commander remote control
Miniature Speaker : Allows "AIBO" to make sounds
Acceleration Sensor : For use in maintaining balance and regaining balance when recovering from a fall
Angular Velocity Sensor : For detecting rotary motion

6. Other Features

- Powerful 64-bit RISC processor
- Equipped with 16MB of Main Memory

Yes you saw that for real, I can and will repair most faults to the pcb contained within the battery of all Aibo models.

One of the biggest killers of Aibo batteries is lack of use, yes this may sound odd but when the cells drop below a certain value a protection circuit kicks in and then this prevents the cells form being charged (as it could overload the charging circuit and/or damage the battery).

This protection circuit is necessary because of the way lithium ion batteries are charged.  Their initial charge period is called constant current where the current is allowed to ramp up to the max available by the charging circuit.

After this initial flood charge period the battery will achieve it's potential max voltage (8.4volts for 7.4 volt packs) the charger then switches to constant voltage charging mode where the voltage is held at 8.4 volts (for 7.4 volt packs) and the current is slowly reduced by the battery demanding less and less from the charging circuit.

Eventually this current will drop to the float level which is the value required to keep the pack topped up but not over charge it and cause overheating.


Aibo batteries suffer have this charger design and like most lithium ion battery packs they are of the smart battery design, this has some of the protection circuitry within the battery itself and is part of the problem that Li-ioN smart batteries suffer from as a whole.

Once that pack voltage drops below a certain threshold it's days are numbered.

What this then means is that the voltage inside can only drop as the cells gradually leak voltage unless charged to a very specific storage charge, flaws in the design of the circuit meant that even new unused batteries become useless after prolonged periods of storage.

This then created that catch 22 situation where the battery needed charging but the battery refused to let the system charge it - effectively disabling itself forever (in most cases).

The internal cells then continue to reduce in voltage until they get to a stage that they will never recover, even if they are charged outside of their internal charging circuitry by opening the case.  This is the case for the vast majority of original Aibo 110/111/210/220/300 and 7 series batteries and re-celling is the only option.

We can replace the cells in all models of battery and when re-celled the batteries will be of a higher capacity than they were when manufactured as the batteries available today have higher energy densities than were available back then.  However this does not necessarily mean your AIbo will run twice as long with a 4ah cell structure as opposed to a 2ah one.

The reason for this is that inside there is a control circuit that knows exactly what the programmed capacity of the battery is and this configuration is protected by a password so just putting bigger capacity batteries in doesn't necessarily mean they will run for longer.

This is however something I have been working on for some time and at some point I hope to be able to replace the existing chip with one of my own programming and then the full benefits of higher capacities will be achieved.

It is worth mentioning that the batteries do run longer but not to their full potential (still longer than standard though).

When it comes to repairing the pcb's within I reserve the right to reject any repairs that are clearly beyond economic repair because a budding diy enthusiast has fried it big time.


We would like to point out that to our knowledge we are the only repair centre that currently re cells ERA-110B batteries for the Sony AIbo ERS-110 & ERS-111 models.  We can also (in most cases) repair ERA-110 batteries that have had unsuccessful re cell attempts made that have left the battery non functional.


The ERS-1100 is a rare version of the ERS-110 that was made exclusively for projects like RoboCup’s Four Legged League in 1999 and 2000.

In 2000, 12 different groups competed, for a total of at least 36 ERS-1100 robots existing.

It’s not known if many of these special pups are still around, but one is known to have spent some time at the AIBO Ranch in California!

If you look closely at the image you can see the rectangular panel in the middle of the ERS-1100′s back isn't fixe like it is in a 110 and is removable. There is also a covered plug on the back of 1100’s head. With these modifications, the RoboCup teams could connect Aibo to a computer to view data and get a better understanding of how Aibo interacts with and sees the world.

In a book published by one of the teams they go into detail about the challenges they faced due to the narrow field of vision and limited external sensor inputs and also the limited cpu compute performance to enable self driven free roaming commands.

Try to remember this was in the days that a self driving car was still in the realm of science fiction and there they were making consumer level robot companions play autonomous football. Quite an achievement really.

The blue battery next to this pup was made exclusively for the ERS-1100. Not much is known about it or what exactly makes it different from a normal first generation AIBO battery other than the labels and color being different, but these batteries are as hard to find secondhand as the robots that use them.



The ERS-2100 is a developer revision of the ERS-210 used in RoboCup competition.



  • 1History
  • 2Function


The ERS-2100 predated the creation of the ERS-210, although the timeframe is unknown. The robots were confirmed to be used during the 2001 RoboCup 4 Legged League. Currently, to our knowledge there are no working ERS-2100 robots present in the community.

If anyone has one I would be willing to try to repair it even if it has broken parts as I can try to reproduce the broken items using our single item manufacturing processes.  We also have full logic repair technologies to try to repair any logic board problems.


The ERS-2100 is almost entirely unique in it's construction- the modules that make up the model are incompatible with the ERS-210 components, predating their conception and production. The CPU handles 200 million MIPS in comparison to the ERS-210's 100 million. It housed 32MB of memory rather than 16.

The new [ERS-210] has additional movement in both ears and an increased number of LED (face x 4, tail x 2) and touch sensors (head, chin, back) which means that it can show an abundant array of emotions such as "joy" and "anger". In order to increase interaction with people, the [ERS-110] series most distinctive feature, its autonomous robot technology (reacting to external stimulus and making its own judgements) that allows AIBO to learn and mature, has been enhanced. It will now include features frequently requested by AIBO owners such as a Name Recording Function (recognizes its own name), Voice Recognition (recognizes simple words) and Photo Taking.

The technologies that allow the [ERS-210] to communicate, such as the autonomous feature which gives AIBO the ability to learn and mature plus the voice recognition technologies etc. will be available on a special flash memory AIBO Memory Stick software application (Autonomous AIBO-ware) called "AIBO Life" [ERF-210AW01] (*sold separately). So that people can enjoy using AIBO in a variety of new ways an additional two application software (AIBO-ware), "Hello AIBO! Type A" [ERF-210AW02] demonstration software and "Party Mascot" [ERF-210AW03] game software (*both sold separately), are also being introduced. A new line-up of AIBO accessories such as a carrying case and software that enables owners to perform simple edits to AIBO's movements and tonal sounds on a home PC will also be offered to personalize the way owners can enjoy interacting with their AIBO.

Similar to previous AIBO product offerings orders will be accepted by the Internet and telephone, in addition orders will also be accepted for the first time at various retail outlets to allow people to actually experience the product first-hand and understand the charm of AIBO. The stores (department stores, Sony Plaza etc.) have agreed to set up special in-store "AIBO Shops" to display the product and give customers the chance to experience AIBO.

This year on August 1, with the aim of developing a genuine entertainment robot business, the ER Business Division became a separate "Entertainment Robot Company" (ERC) within Sony Corporation. In the future Sony is not solely interested in testing the market and developing the technology for entertainment robots, but is committing itself to establishing and expanding the consumer market for entertainment robots.

(*) Sales of AIBO [ERS-210] are planned for- Austria, Greece, Denmark, Finland, France, Germany, Ireland, Italy, Luxembourg, Portugal, Spain, Switzerland, the UK, Belgium, Holland, Sweden, Norway.

Main Features of "AIBO" [ERS-210]

1) 3 Different Color Variations
The [ERS-210] is available in three color variations (silver, gold and black) so customers can choose the one that suits them best.

2) Autonomous Robot AIBO - actions based on own judgement
When used with Memory Stick application (AIBO-ware) "AIBO Life" (*sold separately) [ERF-210AW01] AIBO acts as a fully autonomous robot and can make independent decisions about its own actions and behavior. AIBO grows up with abundant individuality by interacting with its environment and communicating with people by responding to its own instincts such as "the desire to play with people" and "the desire to look for the objects it loves".

3) Enhanced Features to Express Emotions
When used in conjunction with "AIBO Life" (*sold separately) AIBO [ERS-210] owners can enjoy the following features to their full capacity:

(1) Touch Sensors on the head, chin and back
In addition to the sensor on the head, new touch sensors have been added to the back and under the chin for more intimate interaction with people.
(2) 20 Degrees of Freedom
A greater variety of expressions due to an increase in the degrees of freedom of movement from 18 on the [ERS-110] and [ERS-111] (mouth x 1, head x 3, tail x 2, leg x3 per leg) to 20 degrees of freedom with new movement added to the ears on the AIBO [ERS-210].
(3) LED on the Tail
In addition to LED (light-emitting diodes) on the face, LED have been added to the tail. A total of 4 LED on the face (expressing emotions such as "joy" "anger") plus 2 on the tail (expressing emotions like "anxiety" "agitation") allows AIBO to express a greater variety of emotions.
4) Enhanced Communication Ability with New Advanced Features
When used in conjunction with "AIBO Life" (*sold separately) AIBO [ERS-210] has the following features:

(1) Personalized Name (name recording & recognition):
Owners can record their own personal name for "AIBO" and it will respond to this name by actions and emitting a special electronic sound.
(2) Word Recognition (voice recognition function):
Depends on AIBO's level of development and maturity. The number of words and numbers AIBO can recognize will change as it grows up until it can recognize about 50 simple words. In response to the words it recognizes AIBO will perform a variety of actions and emit electronic sounds.
(3) Response to Intonation of Speech (synthetic AIBO language):
When spoken to, "AIBO" can imitate the intonation (musical scale) of the words it hears by using its own "AIBO language" (tonal electronic language).
5) Photo Taking Function
If used in conjunction with "AIBO Life" and "AIBO Fun Pack" software applications (*both sold separately) AIBO will take a photograph of what it can see using a special color camera when it hears someone say Take a photo. Using "AIBO Fun Pack" software [ERF-PC01] photographs taken by AIBO can be seen on a home PC screen.

6) Wireless LAN Card
By purchasing a separate IEEE802.11b "AIBO Wireless LAN Card" [ERA-201D1], inserting it into a PC card slot and using "AIBO Master Studio" software (*sold separately) the movements and sounds AIBO makes can be created on a home PC and sent wirelessly to control AIBO's movements.

7) Other Features

Sony really broke the mould when it realised the first Aibo back in 1999.

Aibo DHS or Droopy Head Syndrome (alternately known as Dropping Head Syndrome) is a behaviour that is characterised by the head of the Aibo uncontrollably dropping when passing past the midway point of downward travel in the neck joint.  This problem is caused by a design flaw in the servo mechanism that controls the head's neck joint.

The same servo's are used for the tilt axis and the pan axis similar problems are known to occur in this joints also.

The design flaw is where the manufacturer of the servo (let's say Sony for arguments sake) utilised a very compact method of preventing damage to the gearing system used inside the servo when shocks impact the head or the heads movement is restricted.  To enable such a tiny unit (Aibo is very compact after all) the unit uses a planetary gearing system with multiple drop down stages to amplify the torque that the motor puts out to enable it to move the head joints relatively quickly and smoothly.  The side effect of this is that if the head is jammed or stopped from moving (say perhaps from a child holding onto it) this would cause the motor to have a high chance of causing itself or it's gearbox some irreparable damage.  In practice this never seemed to be the problem as the method used was a plastic insert in-between a bell housing and an internal spinner shaft that was designed to create enough friction to spin both parts at the same time but allow slippage if needed.

Unfortunately it didn't quite work out that way and the insert became worn far too quickly and caused slippage well before the initial warranty period of 1 year had elapsed in most cases.  What was even more unfortunate was that this same part seemed to become brittle with age so even new in box units that had been untouched for many years could come straight out of the box and exhibit symptoms of DHS,PAS or TAS straight away without any prior use.

As time went on the spares supply dwindled to the point where there were almost no spare head assemblies left available and other solutions needed to be found.

One such method utilised a small hole being drilled and a pin inserted through all three components literally fusing the assemblies together.

I wasn't happy with this method as I felt it caused undue stress on the shaft (which then had a hole in it) and a high likelihood of allowing irreparable damage and as such I developed my own method which to date has never failed and doesn't weaken the shaft at all.  It also incorporates a failure point should the head be knocked violently.  Without this failure point a pinned servo slipper clutch gearbox would literally destroy itself as all the gears inside it are plastic.

From time to time I have come across modified servos that have done exactly this as they have stripped the teeth off all 3 planetary gears that act on the outer casing of the gearbox.  This particular problem was very time consuming to fix as I had to try to source replacement gears (which I couldn't) and in the end manufacture my own replacements to bring these poor pups back to life.

Needless to say when it comes to the DHS,PAS,TAS three amigos I know all there is to know about repairing them.
