    Project Experience

    2022 - Now
    Huawei Technologies Co., Ltd.
    Indoor Positioning System (IPS) is an emerging technology that is widely applied in indoor navigation, urgent evacuation, human activity analysis, etc. We propose a unified and versatile framework to seamlessly fuse traditional IPS with prior knowledge and onboard perception system to solve the challenges.

    This project aims to develop a highly integrated AGV (automated guided vehicle) cooperative system for material handling and conveying in smart and reconfigurable manufacturing to meet the demand of LVHM production. The system is autonomous and intelligent in terms of optimal transportation path planning, reconfigurability, fault tolerance, and cost effectiveness.

    In Collabration with ST Engineering, Singapore
    The project aims to develop light-weight obstacle detection and avoidance technology for UAVs that are operating in a GPSless, indoor environment. Traditionally, obstacle detection is achieved using a LiDAR or a camera. However, LiDAR operates only in the 2D plane, has limited viewing angles and is often costly to implement. Hence, in this project, it is proposed to develop a light-weight 3D obstacle avoidance technology based on time of flight sensors such as those from Intersil. The obstacle detection and avoidance system will be integrated with the UWB based localization and navigation system to achieve safe navigation in complex GPSless, indoor environments.

    In Collabration with STMicroelectronics, Singapore
    This project aims to develop speech recognition system to manipulate drones. Most drones requires manual or remote manipulation to take off and land. Existing speech recognition requires either online training or huge computational cost. In this project an offline speech recognition algorithm is designed and implemented to STM32 on board processor. The UAV is able to listen to voice command and execute task without manual control. We won the 1st place in Singapore Amazing Flying Machine Competition.
    2013 - 2014
    Undergraduate Research on Campus (URECA)
    The project aims to develop an intelligent task planning algorithm for container terminal operation. Epuck robot is used to simulated individual transportation truck in the container terminal map designed based on real container terminal in Singapore. The algorithm optimizes the time cost under various parallel tasks input to the system. In the meantime, collision avoidance is garanteed.
