Ubitus announced a collaboration with MacKay Memorial Hospital to debut Artificial Intelligence powered multi‑modal medical robots at Nvidia GTC Taiwan 2025. In a session titled “Artificial Intelligence enabled healthcare: multi‑modal robot collaboration inspired by MacKay’s case study,” the partners detailed how Nvidia technologies including Blackwell GPUs, Omniverse, Isaac GR00T, ACE, and Jetson AGX Orin are being combined to automate routine tasks, improve patient services, and increase operational efficiency inside hospitals.
The project produced three distinct robots tuned for hospital workflows. An autonomous mobile robot equipped with a virtual assistant handles patient navigation, interactive companionship, and registration assistance to streamline front‑of‑house operations. A humanoid robot built on Nvidia Isaac GR00T N1 provides advanced dual‑arm manipulation for autonomous specimen transport and material handling in unmanned environments, targeting logistics bottlenecks. A quadruped robot running on Nvidia Jetson AGX Orin with Isaac GR00T ReMemBr and X‑mobility traverses high‑risk, hard‑to‑reach areas to perform environmental monitoring such as gas detection, thermal sensing, and water leakage detection, transmitting real‑time data to reduce safety risks.
To enable natural, multilingual interactions, each robot uses Nvidia Blackwell GPUs paired with the Llama 4 large language model and Nvidia Riva. The virtual assistant leverages Nvidia ACE digital human technologies to present customizable avatars that provide emotional support, health education, and companionship, with the goal of delivering more empathetic patient engagement alongside functional guidance.
Before deployment, the teams relied on Nvidia Omniverse and Isaac Sim to recreate hospital environments, run virtual tests, and train tasks. This virtual‑physical integration reduced risk and cost, shortened rollout timelines, and helped optimize workflows. Ubitus CEO Wesley Kuo said the partnership positions MacKay as the first smart hospital in Taiwan to adopt Nvidia B200 and demonstrates the real‑world impact of Artificial Intelligence in healthcare. Looking ahead, Ubitus plans to expand the collaboration across emergency, inpatient, rehabilitation, and long‑term care settings to deliver scalable solutions that integrate Artificial Intelligence into clinical workflows. MacKay’s leadership and staff cited improved patient service quality, optimized internal processes, enhanced safety management, lower workloads, and better clinical efficiency as early benefits.
