OTSAW TransCar, Camello+ & O-R3 Robots

OTSAW is a robotics group founded in 2015 in Silicon Valley and now headquartered in Singapore through OTSAW Digital and OTSAW Healthcare Robotics, with a team in Boston. It builds AI-driven autonomous robots for healthcare intralogistics, security, last-mile delivery and disinfection, targeting staff shortages in hospitals and estates.

TransCar is an automated guided vehicle that hauls trolleys of up to 500 kg through hospitals, with onboard weight sensors that log tonnage and food waste. Camello+ is a modular indoor-outdoor AMR for delivery and patrol, with individually locked compartments opened by RFID card or QR code. The O-R3 outdoor security robot uses patented 3D SLAM navigation, HD cameras with 360-degree computer vision and real-time alerts. TransCar serves KK Women's and Children's Hospital and Singapore General Hospital.

• TransCar AGV: heavy-duty hospital porter that hauls trolleys of up to 500 kg.
• Weight sensing: onboard sensors record tonnage delivered and food waste.
• Camello+: modular indoor-outdoor AMR for delivery and security tasks.
• Secure compartments: lockers opened by RFID card or QR code with access logs.
• O-R3 security robot: outdoor patrol with patented 3D SLAM and auto return-to-base.
• Video analytics: HD cameras with 360-degree vision and real-time alerts.

A large hospital in Hanoi or Ho Chi Minh City can use TransCar to move meal and linen trolleys between kitchens and wards. A township or industrial park can deploy O-R3 for night patrols of roads and car parks. A university or resort can use Camello+ for secure parcel delivery across buildings.

TransCar runs 24/7 with a 500 kg payload, and the company states that a fleet of 20 units completes over 1,000 jobs per day. Weight data from TransCar supports food-waste analysis and sustainability reporting. Camello+ fills gaps when porters or guards are short, with tracked access to each compartment. O-R3 adds round-the-clock mobile patrols that complement fixed cameras.

Hospitals in Singapore, Japan and across Asia face ageing populations and porter shortages, which is driving adoption of AGVs for meals, linen and supplies. Security firms are also adding autonomous patrol robots to offset guard shortages, a need that is emerging in large Vietnamese hospitals, townships and industrial parks.

Founded in 2015 in Silicon Valley; parent Otsaw Robotics is headquartered at 10 Tampines North Drive 4, Singapore, with entities OTSAW Digital and OTSAW Healthcare Robotics. In November 2025 it named Moraine Corporation, a Japanese medical distributor serving over 3,000 hospitals, as its strategic distributor in Japan. Also offers Robot-as-a-Service and a partner programme.
