Robotics and Artificial Intelligence are two promising directions in the future. RoboMaster University AI challenge is an AI-based robotics challenge for university students aimed to inspire AI and robotics research for young engineers and scientists.
Play2study is an interactive and fun educational game app. Currently, it is targeted to HKDSE candidates who study Chemistry (we plan to expand into other subjects in the future), with each chapter of the game corresponding to relevant topics of the syllabus. This game is a vivid example of ‘saying no to just reading long boring texts and books’. Upon playing this game, users can find their strengths and weaknesses in each topic and various skills, which will be provided by the game through detailed analysis from the users’ gameplay.
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.
BREED is a student group committed to developing and promoting bio-inspired technology. Our flagship VAYU project – the world’s fastest robotic fish – and our upcoming initiatives such as our robotic dog aim to educate and enhance awareness in the general student body. Using designs perfected by millions of years of natural evolution, we adapt selected features into increasing effectiveness of man-made robots. We aim to establish a hub based in the Innovation Wing where this development can take root in the local community, increasing awareness and interest while promoting scientific innovation: this will be done through outreach projects, educational initiatives, as well as the continuation of various bio-inspired initiatives under BREED.
Due to the outbreak of COVID 19 pandemic, over millions of people infected in foreign countries every day. To fight back the coronavirus, we are here to present our product – SORBOT. SORBOT is an ozone sterilizing robot combining AGV technology and ozone generator. Ozone is a non-polluting method to sterilize the air. Robot Operating System will act as a bridge for the controlling programs of both motors and the sensors to communicate and coordinate. Using both cloud and database platforms, we can provide an easy monitoring system for our customers to track the ozone concentration and robot inside a room area. We believed that it is beneficial to the public.
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.
Due to the outbreak of COVID-19, a face mask has help us to reduce the spread of the COVID-19 viruses. The use of the mask has been substantially increased. For further enhancing the functionality of the mask, it is desirable for developing a smart product with an integration of digital technologies, including IoT, AI, mobile devices, and cloud computing. The smart product has the following features to minimize the spread of the COVID-19:
The Chair Stacking System(CSS) aims to build an intelligent system for the centre that helps to stack up chairs in conference rooms. The chair stacking system detects and stacking chairs automatically. The machine mainly consists of lifting system and robotic arms system, which is programmed by using Arduino platform. The lifting system acts as the basic support, and it controls vertical position of the arms. The robotic arms provide accurate movement to grab chairs in hand. Various mechanisms that are used, including belt-driven actuator, lead screw actuator, rack and pinion, and etc.
Chloride attack of concrete in particular for marine structures is a serious global issue where it can lead to severe deterioration of the concrete, drastic reduction in strength of structures and safety concerns. The world is urging for a remedy to this situation. A green alternative to Ordinary Portland Cement (OPC), Alkaline-activated Slag (AAS), is found to be having 70%-150% higher chloride binding capacity than that of OPC, making it a potential antidote to this issue. This project aimed to analyse the chloride resistance of AAS in the marine environment, to provide better predict the service life of marine structures and to find ways to enhance the durability of concrete in aggressive conditions. With AAS, let us ‘cement’ a sustainable future.
Seawater desalination offers the vast potential of producing unlimited clean water. Membrane-based desalination technologies can be used to produce alternation water source. Reverse osmosis (RO) is regarded as a reliable technique for seawater desalination. Most RO membranes have a thin-film composite (TFC) structure, and the performance of the membrane is predominantly determined by the physiochemical properties of the polyamide (PA) layer. The performance and the formation mechanism of the PA layer have been intensively studied in recent years. This project aims at fabricating the TFC membrane using a support-free IP reaction, and to explore the formation mechanisms of the PA layer in the SFIP reaction system. Results show that the performance of the fabricated RO membranes is satisfactory.
