Situated Knowability: 공간-맥락적 인식 가능성 연구

Mobile Robots (Physical)

Four kinds of mobile robots in the physical world Four stationary mobile robots stand over a floor whose flowing contour lines indicate forward motion.

World Model (Virtual)

A virtual world model connecting perception, memory, and action A translucent brain connects spatial representation, memory, uncertainty, a world model, world state, and action.

Mission & Vision

Our Lab's Mission

00

To build an intelligence that understands what is observed, what remains uncertain, and what evidence is needed for reliable action.

Our Lab's Vision

01

To build a scientific foundationfor sensor-based understanding of real-world environments, grounded in observability, uncertainty, and spatial reasoning.

02

To develop robot perception systemsthat can localize, map, recognize, and interact with the physical world while knowing the limits of their own perception.

03

To advance spatial representationsthat support certifiable world claims, cross-modal reasoning, long-term memory, and operation under ambiguity and change.

04

To define the principlesthat let robots identify what is observable, locate the boundary of reliable perception, and acquire the evidence needed for action.
