Kubo Care uses radar technology to keep elders safe at home

Kubo Care is a home-monitoring system for older people. Its main device mounts on a wall or ceiling and uses 60 GHz millimetre-wave radar. It tracks presence and movement without recording video or audio. This helps families and care teams monitor seniors while protecting privacy.

The sensor sends radio signals through a room and creates a three-dimensional map of movement. Kubo Care’s AI analyses this spatial information and identifies movement patterns. A sudden fall can be detected in less than a second. The system can also distinguish a fall from someone deliberately lowering themselves slowly onto the floor.

Kubo Care converts raw point-cloud data into skeletal models that show posture and gait. It has patented software designed to reduce false alarms by more than 99%. The technology is being piloted in India, Japan, and the US, with plans to expand through senior care operators.

The article says more than half of serious falls occur in bathrooms. This makes bathroom monitoring especially important, but cameras may feel intrusive there. Kubo Care’s radar offers another approach because it tracks movement without capturing video or audio.

The system uses a wall- or ceiling-mounted 60 GHz millimetre-wave radar device. It sends radio signals to map a room in three dimensions. Proprietary AI studies the resulting spatial data and recognises sudden changes in posture and movement. Kubo Care says it can detect falls in less than a second.

Speed is only part of the design. The system also distinguishes sudden falls from deliberate actions, such as slowly lowering onto the floor. Its patented method reportedly reduces false alarms by more than 99%. Kubo Care is testing the technology in India, Japan, and the United States.

Radar can be less intrusive because Kubo Care’s system monitors movement without recording video or audio. This matters in private spaces such as bathrooms, where the article says more than half of serious falls occur. Families can receive useful safety information without continuous visual or sound recordings.

The device sends 60 GHz radio signals through a room and creates a three-dimensional map. Kubo Care’s software turns point-cloud data into skeletal models showing posture and gait. AI then interprets movement patterns, rather than storing a camera image or microphone recording. The system can identify falls and routine changes.

Wearables have a different weakness: seniors may forget to wear or charge smartwatches and panic pendants. Radar is mounted in the home and monitors continuously. It is not completely invisible, since hardware must be installed, but it avoids the article’s concerns about intrusive cameras and unreliable wearable use.

When Kubo Care detects a possible fall, its system can generate alerts for the people responsible for care. The information is available to care facility staff through an enterprise management portal. Family members can access it through a mobile application, helping them stay informed even when they live elsewhere.

The software also watches for changes in established daily habits. It tracks sleep restlessness, night-time awakenings, and washroom visits. For institutional operators, alerts can be customised for events such as bed exits, prolonged washroom stays, and wandering. The system can connect to sensors measuring temperature, humidity, lighting, and air quality.

Routine changes are not presented as diagnoses. Instead, they can help care teams identify possible issues, including urinary tract infections or gradual vision decline. Kubo Care is currently conducting pilots in India, Japan, and the US. It plans to expand its B2B work before a broader direct-to-consumer launch.

Full-time attendants require trust and may not always be reliable. Cameras can feel intrusive, especially in bathrooms. Smartwatches and panic pendants provide another safety option, but seniors may forget to wear or charge them. Kubo Care is designed to address these limitations with continuous, in-home monitoring.

Its wall- or ceiling-mounted radar sends radio signals through rooms and tracks movement in three dimensions. The system does not capture video or audio. AI analyses spatial data, detects falls, and learns daily patterns such as sleep and washroom visits. Multiple devices can pass tracking data between rooms in larger spaces.

This does not make the system a replacement for every form of care. Kubo Care is a monitoring and alert platform, not a human attendant. It is currently pre-revenue and running pilots in India, Japan, and the US. Its planned B2B customers are senior care operators, with a future direct-to-consumer launch also planned.

Kubo Care is developing its system for senior care operators and institutional care facilities. The platform gives staff an enterprise management portal with customisable alerts. Family members can use a mobile application to stay informed about relatives living at home. The company also plans a broader direct-to-consumer launch.

Its technology can monitor falls, bed exits, wandering, prolonged washroom stays, and changes in daily routines. Hardware can work across larger spaces by transferring tracking data between multiple wall-mounted devices. This supports continuous monitoring as residents move between rooms, including areas with blind spots.

Kubo Care is conducting pilots in India, Japan, and the US and is currently pre-revenue. It plans to expand B2B operations across those countries over the next year. The founders describe Japan and the US as the two largest senior living markets in the world. In India, retirement community developers are integrating the hardware into model homes.

Millimetre-wave radar is the sensing technology behind Kubo Care’s device. The system uses 60 GHz radio signals to map a room in three dimensions. Point-cloud data is the resulting collection of spatial information about people and their movement. It represents where movement occurs without creating a video or audio recording.

Kubo Care’s patented software converts raw point-cloud data into real-time skeletal models. These models represent posture and gait. The company’s proprietary artificial intelligence analyses the spatial data and looks for movement patterns. It can recognise a sudden fall, distinguish it from deliberate lowering, and track routines such as sleep or washroom visits.

This approach lets the system monitor movement while avoiding camera images. In larger spaces, software transfers tracking data among multiple wall-mounted devices. Kubo Care says a patented method reduces false alarms by more than 99%. The system is being piloted in India, Japan, and the US, with B2B expansion planned.
