02 / THE WORKBENCH
Robotics tools and research experiments,
with a closer look at how they work.
Robot interaction
A ROS 2 teleoperation tool that maps a gamepad to UR5e end-effector motion and Robotiq gripper commands.
Robot perception
A ROS integration that turns camera images and text prompts into object masks and labels using Grounding DINO and Segment Anything.
Research tools
Experiments in loading research papers, splitting their text, and asking language models questions about selected passages.

04 / ABOUT
RESEARCH INTERESTS
I work on how robots sense, localize, and collaborate.
I am a Research Fellow at the Centre for Advanced Robotics Technology Innovation, Nanyang Technological University, Singapore. My work spans multi-robot localization, active perception, and collaborative control. Alongside research, I build tools for robot interaction and experiment with language models for working with papers.
05 / VISITORS
Different places.
Shared curiosity.
Visits are grouped by approximate country or region. Map points represent regions, never a visitor’s exact location. This feature stores aggregate counts, without IP addresses, cookies, or individual profiles. A short-lived timestamp in this tab helps avoid counting reloads within 30 minutes. Counts are visits, not unique people; other tabs and blocked storage may count separately. Do Not Track and Global Privacy Control preferences are respected. Statistics start when this feature goes live.
Map data: Natural Earth, public domain. Boundaries and positions are approximate.
