OVERVIEW

The Sony aibo ERS-311 LATTE is a discontinued robotic companion dog designed for personality development, voice interaction, emotional expression, photography, longer battery life, and collecting.

Released in 2001 alongside the ERS-312 MACARON, LATTE uses 15 degrees of freedom, a 100,000-pixel CMOS camera, stereo microphones, infrared distance sensing, acceleration, vibration, inclination, head, tail, and paw sensors.

The approximately 1.5 kg robot originally operated for about 2.5 hours, could respond to voice commands, take up to seven photographs, and expressed emotion through a horn-shaped head lamp.

The ERS-311 LATTE is now primarily a collectible and legacy companion robot, with its practical use shaped by battery health, original software, included accessories, sensor condition, and the availability of repairs.

FAQ

Frequently asked questions

How much does the Sony aibo ERS-311 cost? +

The Sony aibo ERS-311 price was 98,000 yen excluding tax at its 2001 Japanese launch, but it now has no official Sony retail price. Current collector value depends on cream LATTE condition, battery, charger, AIBO-ware Memory Stick, stand, ball, packaging, accessories and repairs. A displayed figure is not always the final delivered and usable cost. Buyers may also need to account for shipping, taxes, customs duties, batteries, controllers, payloads, software, subscriptions, installation, training, warranty, spare parts, local support and application integration.

Before comparing offers, confirm the exact model or condition, commercial status, included hardware, software rights, delivery terms and after-sales process. The better buying question is: what is included, what is excluded, and who supports the robot after delivery?

You can request Sony aibo ERS-311 pricing, availability or a package review through Anton Robots before committing.

Where can I buy the Sony aibo ERS-311? +

You can request verified used or collector sourcing for the Sony aibo ERS-311 through Anton Robots. Anton Robots helps buyers verify the real commercial route, compare legitimate packages, understand what is included and decide whether the Sony aibo ERS-311 is appropriate for the intended use case. ERS-311 is a discontinued legacy AIBO and is available only through collectors, auctions, specialist sellers and secondary marketplaces.

Before buying, commissioning or importing a unit, confirm the exact version, regional availability, included hardware, software access, shipping, taxes, warranty, spare parts and technical support. A product page, historical launch announcement or secondary-market listing does not always mean that a robot is available for immediate supported purchase in every country. Professional buyers should compare the complete operational package and support route rather than only the lowest displayed price.

To start, request Sony aibo ERS-311 buying or sourcing guidance through Anton Robots.

Where can I find a Sony aibo ERS-311 for sale? +

You may find a Sony aibo ERS-311 for sale through AIBO collectors, specialist repair communities and used marketplaces. Finding a Sony aibo ERS-311 for sale is only the first step. Buyers should verify whether the offer is current, new, used, refurbished, backordered, programme-limited, unsupported outside its original region or missing essential accessories. Confirm that the robot is the ERS-311 LATTE rather than ERS-312 MACARON or a later 31-series variant and verify software, battery, charger, camera, joints and sensors.

A useful comparison should cover the exact generation, included equipment, software access, delivery country, expected lead time, warranty, replacement parts and who provides support after delivery. Avoid treating a third-party listing as proof of manufacturer support or legal access to proprietary software.

If you are looking for a Sony aibo ERS-311 and want help checking the offer, contact Anton Robots. We can also compare it with other robots in the same category.

Can I get a quote for the Sony aibo ERS-311? +

There is no current Sony quote, but you can request an ERS-311 used-unit review through Anton Robots. A useful quote or commercial review should identify the exact version, ownership or programme structure, included equipment, software, accessories, shipping assumptions, taxes or import notes, warranty, delivery estimate, training and available support. The review should identify model, colour, AIBO-ware software, battery runtime, adapter, stand, ball, packaging, repairs, provenance and return protection.

Buyers should provide the destination country, intended application, operating environment, required delivery date and any integration needs. That information helps determine whether the robot is commercially obtainable and whether the proposed package is technically suitable. The proposal should also state who commissions the system and what happens if the robot cannot meet the intended workflow.

Anton Robots can help compare the Sony aibo ERS-311 against other relevant robots.

What is included when you buy the Sony aibo ERS-311? +

A typical Sony aibo ERS-311 package originally included the ERS-311 robot, AC adapter, conversion plug, lithium-ion battery, stand, pink ball and documentation. The exact contents vary by seller, programme, configuration, product condition and country, so buyers should request a written packing and service list:

  • Sony aibo ERS-311 LATTE robot
  • ERA-301B1 battery and AC adapter
  • Stand and pink ball
  • Compatible AIBO-ware Memory Stick
  • Documentation and original packaging
  • Optional Energy Station core or carrying bag
  • Condition and repair history
  • Protective shipping and seller guarantee

The autonomous personality depends on compatible AIBO-ware, while optional charging-station equipment was sold separately. Hardware, software and support are often separated in robotics purchases. A low advertised price may exclude the charger, controller, compute, payload, spare battery, installation, training or warranty handling required for practical use. For business, education, research and collector buyers, the complete operational package is more important than the headline price.

You can request an itemised Sony aibo ERS-311 offer or availability review through Anton Robots before committing.

What was the original Sony aibo ERS-311 price? +

Sony launched the ERS-311 LATTE at 98,000 yen excluding tax in Japan in 2001. It was sold alongside the mischievous black ERS-312 MACARON through online, telephone and normal retail channels. The practical result depends on the exact configuration, software, environment, accessories and operator workflow rather than the headline specification alone. Historical price does not determine current collector value and excludes the condition, software, station and rarity of a specific unit.

Before buying or deploying the robot, verify model authenticity, colour, software, battery, accessories, packaging, repairs, recent sales and buyer protection. A proper evaluation should use the real tasks, routes, objects, users or operating conditions instead of relying only on a promotional video. Price the exact complete working robot.

You can request Sony aibo ERS-311 application advice through Anton Robots and compare the complete package or a more suitable alternative.

What is the difference between Sony aibo ERS-311 and ERS-312? +

The ERS-311 is the cream-coloured LATTE with an adorable personality, while ERS-312 is the black MACARON with a mischievous personality. The two models share the same core 15-axis hardware, camera, sensors, battery platform and 31-series design. The practical result depends on the exact configuration, software, environment, accessories and operator workflow rather than the headline specification alone. Later variants and software can change colour, behaviour or packaging, so appearance alone does not prove the exact model.

Before buying or deploying the robot, verify model label, shell colour, software Memory Stick, documentation, serial number, accessories and boot behaviour. A proper evaluation should use the real tasks, routes, objects, users or operating conditions instead of relying only on a promotional video. Choose between them mainly for design, personality and collector preference.

You can request Sony aibo ERS-311 application advice through Anton Robots and compare the complete package or a more suitable alternative.

How long does the Sony aibo ERS-311 battery last? +

Sony originally specified approximately 2.5 hours of operation using a fully charged ERA-301B1 battery. The battery charged in approximately 1.5 to two hours under the original specification. The practical result depends on the exact configuration, software, environment, accessories and operator workflow rather than the headline specification alone. Original batteries are now old and may have reduced runtime, swelling or unsafe cells, while rebuilt packs vary in quality.

Before buying or deploying the robot, verify battery origin, rebuild service, measured runtime, charging temperature, adapter, contacts, swelling and replacement availability. A proper evaluation should use the real tasks, routes, objects, users or operating conditions instead of relying only on a promotional video. A good battery can materially improve the usability and value of an ERS-311.

You can request Sony aibo ERS-311 application advice through Anton Robots and compare the complete package or a more suitable alternative.

How many degrees of freedom does the Sony aibo ERS-311 have? +

The ERS-311 uses 15 degrees of freedom. Three axes in the neck and three in each of the four legs support walking, posture and expressive companion movement. The practical result depends on the exact configuration, software, environment, accessories and operator workflow rather than the headline specification alone. It has fewer movable ears, tail and facial mechanisms than ERS-210 or ERS-7, and ageing joints may not deliver original motion quality.

Before buying or deploying the robot, verify all legs and neck joints, startup motion, abnormal noise, looseness, cracking, falls and repair history. A proper evaluation should use the real tasks, routes, objects, users or operating conditions instead of relying only on a promotional video. Its simpler mechanism contributes to its distinct relaxed character.

You can request Sony aibo ERS-311 application advice through Anton Robots and compare the complete package or a more suitable alternative.

Can the Sony aibo ERS-311 take photos? +

Yes, the ERS-311 can take up to seven photographs in response to a voice instruction. A 100,000-pixel CMOS camera in the mouth stores JPEG images on the compatible AIBO-ware Memory Stick. The practical result depends on the exact configuration, software, environment, accessories and operator workflow rather than the headline specification alone. Image quality is extremely low by modern standards, and the function depends on the correct software, Memory Stick and healthy camera.

Before buying or deploying the robot, verify camera image, voice command, Memory Stick, file transfer, lighting, software version and stored-photo retrieval. A proper evaluation should use the real tasks, routes, objects, users or operating conditions instead of relying only on a promotional video. Treat photography as a historical interactive feature, not a practical camera.

You can request Sony aibo ERS-311 application advice through Anton Robots and compare the complete package or a more suitable alternative.

Does the Sony aibo ERS-311 charge itself? +

The ERS-311 came with an AC adapter and stand, while the Energy Station core was sold separately. Owners can charge the battery with the original compatible equipment and optional station accessories. The practical result depends on the exact configuration, software, environment, accessories and operator workflow rather than the headline specification alone. Automatic self-docking should not be assumed, and missing or damaged charging equipment can make the robot unusable.

Before buying or deploying the robot, verify adapter, conversion plug, battery, station core, contacts, charge cycle, voltage and safe battery condition. A proper evaluation should use the real tasks, routes, objects, users or operating conditions instead of relying only on a promotional video. Ask the seller to demonstrate the exact charging workflow.

You can request Sony aibo ERS-311 application advice through Anton Robots and compare the complete package or a more suitable alternative.

Should I buy Sony aibo ERS-311, ERS-210 or ERS-7? +

Choose ERS-311 for LATTE design and longer original runtime, ERS-210 for iconic expressive mechanics and ERS-7 for the richest original AIBO features. ERS-311 is simpler and personality-focused, while the later or more articulated models add wireless functions, sensors, self-charging and advanced recognition. The practical result depends on the exact configuration, software, environment, accessories and operator workflow rather than the headline specification alone. All require legacy software, batteries and repair support, and condition can matter more than model ranking.

Before buying or deploying the robot, verify collector preference, desired interaction, software, battery, station, repairability, completeness and price. A proper evaluation should use the real tasks, routes, objects, users or operating conditions instead of relying only on a promotional video. A complete working example is better than a theoretically superior but incomplete robot.

Can the Sony aibo ERS-311 be shipped internationally? +

A used Sony aibo ERS-311 can be shipped internationally, but battery rules and fragile legacy hardware require specialist packing. Delivery depends on the destination country, commercial status, freight method, lithium-battery rules, customs, regional certifications and local service coverage. Confirm voltage, adapter, battery condition, customs, software language, spare parts, repair access and seller return terms before import.

Before ordering, ask who acts as importer of record, whether software and warranty remain valid in the destination country and whether installation requires an approved local partner. Buyers should also confirm package dimensions, battery documentation, insurance, damage procedures, data-hosting requirements and any end-use restrictions. A robot that can physically be transported is not necessarily supported, activatable or legally deployable in every market.

You can request international availability for the Sony aibo ERS-311 through Anton Robots so the complete route can be checked.

Is the Sony aibo ERS-311 in stock and how long does delivery take? +

Sony aibo ERS-311 availability and delivery time can change according to production, regional inventory, programme eligibility, product condition, configuration and current demand. Supply is limited to used and collector listings, with complete LATTE packages appearing irregularly and condition varying widely. A robot appearing online should not automatically be treated as locally stocked and ready to ship.

Before committing to a project or event date, ask whether the order is confirmed, backordered, used, refurbished or only an expression of interest, what equipment and software are available and when the complete package can be delivered and tested. Lead time can also be affected by freight, customs, battery transport, software activation, site preparation and training.

You can request current Sony aibo ERS-311 availability through Anton Robots. Buyers should obtain written confirmation of these points before approving a budget, import, research programme, collector purchase, or deployment.

What warranty and support should I check for the Sony aibo ERS-311? +

Before buying or deploying the Sony aibo ERS-311, check the warranty or support term, covered components, exclusions, service territory, repair process, software entitlement, spare-parts availability and who provides technical help. Sony warranty has expired; require a functional test, battery report, seller guarantee and access to independent AIBO parts and repair specialists. Ask these questions:

  • How long is the hardware warranty or seller guarantee?
  • Who handles diagnostics, repairs and replacement parts?
  • Are batteries, joints, sensors, computers and accessories covered?
  • Is software updating, developer support or training included?
  • What happens if the robot cannot be activated or repaired locally?
  • How long will parts, applications and documentation remain available?

For an industrial platform, discontinued robot or collector model, lifecycle support should be a primary buying criterion. Contact Anton Robots to review the package before purchase or deployment.

Is the Sony aibo ERS-311 worth buying? +

The Sony aibo ERS-311 is worth considering if you want the distinctive LATTE AIBO for collecting, nostalgia, exhibition or a simpler long-runtime original companion. Its strongest value comes from its friendly design, 2.5-hour original runtime, voice and touch interaction, photo function and lower-complexity 15-axis body.

However, it is only a good choice when the use case matches the robot’s maturity, commercial status, regional availability and operating limits. It lacks later wireless, self-charging and advanced recognition features and still depends on rare proprietary software and batteries. Buyers should compare complete ownership cost, software access, support, expected lifetime and alternatives that may perform the same task with less risk. For a business, research or collector purchase, define the required outcome and acceptable maintenance burden before committing.
