SIG – BREED Robotics

The robotic fish project provides aspiring engineers with a platform to gain hands-on experience in applied engineering. With design innovation, we enhance the functionality of the fish to further improve manoeuvrability and control.

Our initial goal to make the robot faster and break the world record again has been achieved. Now, the second goal is to solve real-world problems. From discussions with stakeholders, we have identified an opportunity to apply our robot in data collection for marine exploration and pollution monitoring. It can be used to collect water data such as temperature, pH, etc. and also for real-time mapping and monitoring of specimens in the environment such as coral reefs, microplastics, etc.

We envision a series of such projects under the BREED umbrella to promote bio-robotics with a purpose. Ultimately, we hope to create an organisation that drives social impact through innovative robotics solutions.

SIG – HKU UAS (Unmanned aerial system)

HKU UAS is a student interest group focusing on Unmanned Aerial Systems (UAS). We aim to gather self-motivated drone lovers to learn and work on drone projects together. With the support of Innovation Wing, we plan to join competitions to test our knowledge and skills, also to learn from other teams and gain valuable experience. In 2020, the team build the system based on the rules of AUVSI SUAS 2021.
The AUVSI SUAS Competition is a yearly event, designed to stimulate interest in UAS technologies and careers, and to engage students in a challenging UAS mission.

SAE Design, Build and Drive

HKU racing is the University of Hong Kong’s very first motorsports team. Founded in late July of 2018.
Formula Student is a renowned educational engineering competition, combining practical engineering with soft skills including business planning and project management.
WE as a team are now planning on joining FSUK, Which means the Formula student competition in the UK. Team members will design and build a racing car from the ground up. The car is required to perform in numerous dynamic events that will prove the car’s capabilities in terms of speed and reliability.

BREED Robotics

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.

Chair Stacking System

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.

Automatic Chair Parking System

Automatic Chair Parking System aims to provide a smart solution in classroom and other similar environment by helping to move and arrange chairs, while reducing the risk of occupational injuries and potential dangers related to the repetitive works. This can also reduce the reliance on labour force and ultimately improve the efficiency. The system therefore is designed to autonomously transport chairs to the designated parking area with minimal human control.

Fever screening using smartphones

Every day, millions of Hong Kongers use public transport to travel across the city. With the ongoing COVID-19 pandemic, public transport has the potential to spread the novel Coronavirus. This can be avoided if strict preventive measures are in place.

The solution to this is a non-intrusive, real time application that automates fever screening in public transport vehicles. This is made possible thanks to a mobile application that we are developing at HKU. We use a portable thermal camera and a mobile device to detect faces in a stream of thermal images, and then measure forehead temperatures. This can be done in real-time, and requires little to no manual intervention.

Automatic Fabric Roll Edge Extractor

Automation technology has been highly adopted by different manufacturing industries in the past two decades. It shows an increasing investment in research and development throughout these two decades to replace labor in production lines. The leading dyeing and finishing machinery development company Fong’s National Engineering Co. Ltd. offered us a project in device designing to smooth their production line. The head of the raw fabric rolls is usually attached with an adhesive tape to prevent the head from falling out in the transportation process. This project aims to design and build a prototype of an Automatic fabric roll edge extractor with the concept of engineering design thinking. The function of the device is to automate the removal process of adhesive tape without any manpower involved.

Design, Build & Fly 2020 team 3

With the ever-growing demand for air cargo capacity comes the pursuit for cargo aircraft that combine a large payload with optimum efficiency. The Design, Build and Fly team set out to meet this challenge by creating a radio-controlled model airplane, to compete in the Payload Challenge organized by the British Model Flying Association (BMFA). The process involved careful research into aeronautical engineering theories and creative solutions. The effectiveness of the design was proved in test flights by two fully functional prototypes. Various issues were identified during the trials, carefully examined, and subsequently addressed in an iterative manner. The team has continuously implemented modifications to the design, in an effort to produce the model plane that would carry the target payload with the highest efficiency attainable, and the results will hopefully provide useful insights for future model builders and aircraft engineers alike.
