Overview
A patented cable-suspended robotic platform developed at The Chinese University of Hong Kong (CUHK) for inspecting deep foundations — replacing costly and hazardous manual methods like Reverse Circulation Drilling (RCD).
The system uses multiple synchronized winches to lower a robotic platform into deep foundation shafts, where it performs inspection and cleaning operations autonomously.

My Contributions
As a Research Assistant (Dec 2022 – Mar 2024), I developed the control software and led field testing:
- Multi-winch synchronization — Programmed coordinated control of multiple cable winches to ensure stable platform deployment at depths up to 15 meters
- Cable-actuated flexible hose control — Developed control logic for an air-lift cleaning system using cable-actuated flexible hoses
- On-site prototype testing — Led testing in active construction zones, troubleshooting sensor feedback loops and system stability under real-world conditions
Context
Deep-foundation inspection is traditionally done via RCD — an expensive, time-consuming process. This robotic platform provides a faster, safer, and more cost-effective alternative by automating the descent, inspection, and cleaning process.
The work built directly on my mechanical engineering background and set the foundation for my current role in construction robotics, where I apply the same cable-suspended principles at a larger scale.
