Robomaster is a national robotic competition for university students, hosted by DJI during the summer vacation on a yearly basis. It combines technology and e-gaming competition style, thus being exciting and unconventional. HKU Robomaster has been recruiting enthusiastic engineering students since 2017. We aim to cultivate the quality of members that will benefit their career with the practical experience gained during the preparation and participation process. Our work is divided into technical management, machinal & hardware management, and software & algorithm development.

Conventionally, information suffers from exponential decay in long distance transmission. However, in exciting projects like building the quantum internet, an information carrier has to pass through many intermediate quantum servers before reaching the receiver. Such a goal cannot be achieved without a scheme of reliably transmitting data over a long sequence of noisy channels. Chiribella et al. formulated the second level of quantization of quantum information theory by considering the superposition of quantum trajectories and quantum channels and demonstrated communication advantage of this model. We apply the model further and show the theoretical feasibility of communication through asymptotically many noisy channels.

College Mate is a platform for prospective students to find colleges based on country, majors, cost of attendance, etc, interact with current and future students through social media and chat, and estimate and track savings through an in-app financial planner.

Microbially Induced Calcite Precipitation (MICP) is an emerging bio-geotechnical soil improvement technique to enhance the engineering performance of soil. Application of biotechnology has been suggested as an environmental-friendly alternative to conventional approaches. MICP involves using bacteria to hydrolyze urea into carbonate ions through bacterial metabolism. The carbonate ions combine with calcium ions to produce calcite crystal precipitates, which fill the soil pores and bind the soil grains together.

In this project, the effects of several influencing factors on the engineering properties of the MICP treated silica sand are investigated. Permeability and unconfined compressive strength tests will be carried out to characterize the engineering properties of the treated sand. Precipitation patterns of calcite crystals within the sand after MICP treatment will be investigated using Scanning Electron Microscopy (SEM).

We propose a novel smart robotic walker that targets a convenient-to-use indoor walking aid for the elderly. The walker supports multiple modes of interactions through voice, gait, or haptic touch, and allows intelligent control via learning-based methods to achieve mobility safety. Our design enables a flexible, initiative, and reliable walker due to three main functions. Our walker tracks users in front by detecting lower limb gait while providing close-proximity walking safety support. By monitoring force pressure on a specially designed soft-robotic interface on the handle, the walker can detect human intentions and predict emergency events. Our walker performs reinforcement learning-based sound source localization to locate and navigate to the user based on his/her voice signals.
