- Announcement
-
Sony said on June 26, 2026 that it will discontinue Japan sales of the aibo ERS-1000 once remaining stock is sold, ending new-unit availability in the robot’s home market. The ERS-1000 had been on sale in Japan since January 2018, when it launched at 198,000 yen and reportedly sold about 20,000 units in its first six months, according to coverage of the discontinuation.
- Continuing support
-
Sony said existing services, including technical support, replacement parts and AI Cloud Plan subscriptions that store aibo’s memories, will continue for current owners. A company statement quoted in coverage said the aibo business will continue and that Sony intends to expand its range of products and services around the aibo brand, without naming a specific successor.
- Open questions
-
Reporting on the announcement did not specify whether US sales, which began in 2018, are affected, or whether a new hardware model is planned. No timeline for any successor was given in the coverage reviewed.

WatchingWhether Sony formally codifies an institutional licensing tier or continues to route care facilities through standard consumer subscription terms.
Impact on autonomy
- No autonomy capability changes; Level II classification applies equally in care facility context
- Behavioral personalization operates identically in institutional deployment
- Cloud subscription required per unit regardless of deployment context; no bulk licensing mode documented
Impact on readiness

Technical notes4 sections
- Deployment Context
-
Care facility and eldercare home placements of ERS-1000 operate on the same hardware and subscription infrastructure as consumer units. Sony’s facilitated programs in Japan have included subsidized or loaned units for participating facilities, though standard consumer pricing ($2,899 plus $13/month) applies to direct institutional purchases.
- Interaction Pattern Differences
-
In shared care environments, individual Aibo units interact with multiple residents over a day. The cloud-based behavioral personalization layer is designed for single-owner household use; institutional multi-user interaction produces a blended behavioral profile rather than individual adaptation per resident, per care staff observations documented in eldercare research publications.
- Maintenance in Institutional Context
-
Daily charging requirements (2-3 hour runtime per charge, 3-hour recharge) create scheduling demands in care environments where Aibo is expected to be available during waking hours. Facilities report dedicating overnight charging periods and mid-day breaks as the operational pattern. Joint wear timelines under high-interaction care facility use are not separately documented from consumer data.
- Privacy Considerations
-
ERS-1000 transmits interaction data to Sony cloud servers; care facilities deploying Aibo face additional data governance considerations regarding resident interaction data, particularly in jurisdictions with healthcare privacy regulations. Sony has not published care-specific data handling terms.

Aibo ERS-1000 software update adds home patrol and security monitoring
Sony rolled out aibo's first major software update in March 2019, adding a patrol mode that uses onboard cameras to map assigned rooms and check them on a schedule, plus improved head movement and tail-touch sensing.
Full assessment
AutonomyPatrol autonomy capability addedReadinessReadiness status unchangedScoreNo score changeReporting described the update as aibo's first step toward a home-monitoring role. Whether Sony would expand the feature set to full home security remained to be seen.
Impact on autonomy
- Camera-based room mapping enables scheduled patrol without owner input during set hours
- Facial recognition now flags up to ten registered people encountered during patrol
- Head movement and posture control were refined alongside the patrol feature
Impact on readiness
- Update was delivered free to existing owners, requiring no additional purchase
- New patrol alerts route through the companion app rather than a dedicated hub
- Tail-touch sensing added a documented interaction point absent at original launch

Sony described the update as giving aibo a genuine watchdog roleCoverage clarifies the feature is a scheduled room-check with app notifications, not an active security system with monitoring or alarmsThe patrol feature was framed as fully autonomous home protectionReporting describes it as identifying up to ten registered faces and reporting positions through the app, not detecting unknown intruders as a dedicated security device wouldSony presented the update as a natural extension of aibo's existing intelligenceTechnology press treated it as aibo's first major software revision since the January 2018 launch, a notable but incremental capability additionTechnical notes3 sections
- Patrol feature
-
The March 2019 update let aibo ERS-1000 build a camera-based map of a home, with owners able to assign room names through the companion app. Once configured, aibo could patrol the designated areas at scheduled times, playing a Puppy Patrol melody when a patrol began, according to contemporary technology press coverage.
- Recognition and reporting
-
The patrol mode used aibo’s existing facial recognition to identify up to ten registered people encountered during a patrol and report their locations back through the companion app. The feature was described by reporters as aibo functioning as a household check-in tool rather than a dedicated security system.
- Other changes
-
The same software revision also refined aibo’s head movement and posture, improved photo capture quality, and added the ability for aibo to register when its tail was touched, a change reviewers noted as making the robot feel more responsive to physical interaction. Sony had previewed the patrol concept in January 2019, roughly two months before the update reached owners’ units.

- US launch details
-
Sony Electronics opened pre-orders in the US for the aibo ERS-1000 First Litter Edition on September 18, 2018, priced at $2,899.99. An earlier Sony announcement in late August 2018 had confirmed the price and the coming pre-order date. The bundle included the robot, a charging station, a pink ball toy, an aibone chew toy, paw pads, and an individually numbered commemorative dog tag, according to Sony’s own announcement and contemporary coverage.
- Subscription terms
-
The price included a three-year AI Cloud Plan subscription, the service that stores aibo’s behavioral data and lets its personality develop through interaction. Coverage of the launch noted that continued use after the initial three years would require a paid renewal.
- Distribution
-
At launch, the First Litter Edition was sold directly through Sony’s own US aibo website rather than through general electronics retail. Early purchasers were reported to begin receiving their units in December 2018, roughly eight months after the robot’s January 2018 debut in Japan at a lower yen-denominated price.

- Launch details
-
aibo ERS-1000 went on sale in Japan on January 11, 2018, priced at 198,000 yen (excluding tax), about four months after Sony announced the robot’s return on November 1, 2017 following a roughly 12-year hiatus for the aibo brand. Pre-orders opened the same day as the announcement and sold out within roughly a day, according to contemporary reporting.
- Hardware and software
-
The ERS-1000 uses a 64-bit quad-core processor, two OLED displays for its eyes, and 22 degrees of freedom across its joints, giving it a wider range of motion than earlier AIBO generations. Facial and voice recognition let the robot register up to 100 faces and respond to roughly 50 voice commands, per manufacturer-reported specifications cited in launch coverage.
- Cloud dependency
-
Functionality depends on an internet-connected AI Cloud Plan, which stores behavioral data and lets aibo’s personality develop through interaction. The plan is included for an initial period at purchase, with paid renewal required afterward.
