I am currently a Ph.D candidate at the National University of Singapore. My research deals with using mobile robots, to track and follow a target of unknown intentions in an unknown environment, using only local information. I am being supervised by David HSU and Marcelo ANG.

Local Exploration
Quicktime video,	Local exploration deals with mapping the immediate neigbourhood rather than find a map of the whole environment. Our work tries to apply a local greedy approach to move to regions of higher visibility. We find that even though such an approach is meant for efficient local exploration, the robot is able to cover completely even some complicated environments.
