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.

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.
