School of Engineering Department of Electronic and Computer Engineering 149 Coastal Underwater Evidence Search System with Surface-Underwater Collaboration Supervisor: SHI Ling / ECE Student: BAO Fangming / ELEC Course: UROP 1100, Fall The development of efficient robotic systems for locating underwater evidence in shallow coastal areas has long concerned law enforcement. The "Coastal Underwater Evidence Search System with Air-Sea Collaboration" project integrates advanced underwater robots with unmanned surface vehicles to create a search system. The robotic design includes biomimetic underwater robots connected to a boat via tether for control and data transmission. This report mainly focuses on the underwater robot, including its function, limitations, and further improvement. Coastal Underwater Evidence Search System with Surface-Underwater Collaboration Supervisor: SHI Ling / ECE Student: BAO Fangming / ELEC LEUNG Ka Chun / COGBM Course: UROP 2100, Spring UROP 4100, Spring This research introduces an innovative project, aimed at improving underwater evidence search operations in shallow waters. The project addresses the limitations of traditional methods, which rely on divers and tethered remotely operated vehicles (ROVs), by integrating advanced robotic platforms, including underwater robots and autonomous surface vehicles (ASVs). The heart of the system is a biomimetic underwater robot, inspired by efficient marine creatures like crabs and octopuses. The robot can navigate complex underwater terrains with minimal sediment disturbance and establish a collaboration framework between the underwater robot and the ASVs, enhancing their operational range and capabilities. This integration aims to provide a robust solution for law enforcement agencies, particularly the Hong Kong Police Force, to improve their search and recovery operations. Unmanned Delivery Cart Trajectory Planning Supervisor: SHI Ling / ECE Student: ZHU Quanhao / ELEC Course: UROP 1100, Fall This UROP focuses on developing an autonomous delivery system by using a four-wheel differential trolley. The system is designed to pick up and deliver packages within a building, navigating through different floors using an elevator. Key aspects include trajectory planning, path following, and robot arm control. The project also involves studying image acquisition and processing, and mechanical design. The goal is to create a reliable and impressive demonstration of the system’s capabilities. My research this time is aimed at the mechanical design part of the vehicle. The device needs to grab and retrieve objects appropriately leave them on the vehicle, and then take the items out again after reaching the destination, so the design of a practical mechanical arm is very necessary.
