Uni Fighters is a game that we have made for the course COMP3329 – Computer Game Design and Programming. It is a 2.5D fighter game set at the University of Hong Kong, portraying a student who gets into a fight for bumping into his schoolmate. Players will play as a student to fight against the opponent using combat mechanics. We created all the models by ourselves in Blender, including the characters and the map, as well as other assets such as shaders and particle effects using tools like Unity’s Shader Graph and VFX Graphs.

Dynamic state representation learning that can accurately describe dynamics can significantly accelerate reinforcement learning training. However, deformable objects have very complicated dynamics and high DoFs. We propose DiffSRL, an end-to-end dynamic state representation learning pipeline that uses a differentiable physics engine to learn the representation of deformable objects. Our specially designed loss function can guide neural networks to be aware of dynamics and constraints. We benchmark the performance of our methods as well as other state representation algorithms with downstream tasks on PlasticineLab. Our model demonstrates superior performance most of the time on all tasks. We also demonstrate our model’s performance in a real-world setting with two manipulation tasks on a UR-5 robot arm.

Supply chains containing complicated networks of producers, transporters and consumers have played an integral part in the expansion of online and offline businesses worldwide. With so many stakeholders, Supply chain visibility which is the ability to track different goods at each point has become essential. With increased visibility, businesses can optimise their supply chain while consumers can ensure the ethicality of their sourcing practices. However due to inefficient solutions, business owners report poor visibility facing 20% loss in goods annually, whereas most consumers would be willing to pay an extra 2-10% for traced products. Goodchain is a platform consisting of web & mobile applications which provides transparency and traceability in the supply chain through the use of NFT and blockchain. By solving the inefficiencies while catering to all stakeholders in the industry, Goodchain aims to disrupt the supply chain management industry and add immense value to all its members.

In this project, I made a robot dog for STEM education based on 3D printing and Arduino development kit. On top of this, I completed the integration of ESP32 and MPU6050, which gave the robot the ability of motion detection. Through the calculation of the motion data and the implemented PID control system, I completed a very good Self-Balance function. In addition, I also tried to apply the self-balance algorithm to the motion state which improves the motion posture and optimize the performance of the robot dog walking on certain terrain. Finally, I sorted out the problems encountered in the development process and some important principles into a document for STEM education, which can help others better understand and apply related content.
