AUTONOMOUS DRIVING / HUMAN–AI INTERACTION/ PHYSICAL AI/ ASSISTIVE TOOLS
01 / OUR MISSION
Safe decisions. Shared environments.
Our research asks how autonomous systems can act safely when the world is uncertain and other agents are adapting. We connect planning, control and learning to study autonomy in human environments.
Led by Chen Sun at the University of Hong Kong, our work spans field robotics, autonomous driving and human-centered cyber-physical systems.
02 / RESEARCH
From interaction to assurance.
01
Social & interactive
robotics
How should robots anticipate people and navigate shared spaces? We study social navigation and proactive human–robot interaction.
PHYSICAL AI
02
Safe planning &
multi-agent systems
How can vehicles and robots coordinate under uncertainty? We investigate game-theoretic planning and safety-aware decision-making.
PLANNING & CONTROL
03
Trustworthy
autonomous intelligence
How can we understand, calibrate and build trust in AI? We explore social contracts and safety for autonomous systems.
HUMAN-CENTERED AUTONOMY
03 / PEOPLE
The people behind the research.
Exploring safe autonomy, together.
