Project
2023.12-present: Automated welding of complex joints in rebar cages for prefabricated concrete shear walls
Using Yolov9 for target identification and segmentation of complex rebar cage joints, processing point cloud data, predicting the actual 6DOF welding pose based on scene point cloud data. In the future, we will also adopt an end-to-end method to address this problem. Moreover, we have established an automated welding workstation for further research.

2023.05-present: Automated robotic shear stud welding for steel-box beam bridges based on the integration of CAD 2D drawings and structured light camera
We provide an AutoCAD plug-in for extracting the X-Y welding point coordinate of shear studs from CAD drawings and introducing a novel algorithm ‘Fast-Pixel-Matching’ (FPM) for supplementing missing Z-axis coordinate information in 2D drawings and mapping 2D coordinates into 3D space. Based our experiment, the FPM can shorten the positioning process of shear studs from 16.7 hours to 8.6 s for a complex structural component with 6000 studs.
2023.10-present: Tying rebars at the intersection joints of reinforcing cage using robotic arm and UGV
Target identification of stirrup joints is conducted using YOLOv8/CenterNet, guiding the robotic arm to tie the intersection joints of reinforcing cage. We integrated the UR10 robotic arm onto the unmanned vehicle Ranger to accomplish the tying of rebar cages.
2020.03-2022.01: National Undergraduate Training Program for Innovation and Entrepreneurship & Student Research Training Program
Utilizing dynamic analysis software, a coupled vehicle-bridge dynamic analysis is performed on the composite beam bridge composed of vehicles and steel plates. Damping devices are designed for vibration control, and the load-bearing capacity of the steel beams is analyzed using ANSYS.
