Urgent Need

In United States, 4% of patients have at least 1 hospital-acquired infection (HAI), leading to 75,000 deaths per year. Worldwide, 5 to 10% of hospital patients acquire a new infection in hospitals, resulting in millions of fatalities. The number of infections and deaths during pandemic elevates the concerns on public health in hospitals and mass-gathering facilities such as airports. Manual disinfection is the key is time-consuming, labor-intensive, and health-undermining. There is a critical need for automated, intelligent, and precision disinfection to reduce pathogen transmission and exposure, and thus prevent outbreaks of infectious disease and infections alike in hospitals and mass-gathering facilities during pandemic. 

S​olution & Innovation

We make the robot learn when, where, what, and how to disinfect, adapting to the situation and environment. 

  • When to disinfection? The robot can understand the social contexts to plan the disinfection mission and decision. 

  • Where to disinfect? The robot can recognize the high-touch, contaminated, and high-risk surfaces in the room for navigation and disinfection. 

  • What to disinfect? The robot can recognize the object and object surface materials to adapt the disinfection modes.

  • ​How to disinfect? The robot can optimally plan robot trajectories and disinfection parameters for disinfection. 

Research Overview
Research Results


The artificial intelligence (AI) enabled robotic system (value position) adapts to ambient environments, social processes, and building dynamics for automated, continuous, and precision disinfection, thus maintaining environment hygiene and health, and reducing unnecessary labor costs for cleaning and opportunity costs incurred from infections.
