Propeller-Assisted Robust 3D Hopping Robot with Hierarchical Force Allocation
Chuhan Zhang, Hongbo Zhang, Yanlin Chen +4
Monopedal hopping robots are conceptually simple but highly dynamic and inherently unstable. Achieving robust 3D hopping is still difficult because ground reaction forces are avail…
Learning to Hop for a Single-Legged Robot with Parallel Mechanism
Hongbo Zhang, Xiangyu Chu, Yanlin Chen +4
This work presents the application of reinforcement learning to improve the performance of a highly dynamic hopping system with a parallel mechanism. Unlike serial mechanisms, para…
Needle Segmentation Using GAN: Restoring Thin Instrument Visibility in Robotic Ultrasound
Zhongliang Jiang, Xuesong Li, Xiangyu Chu +5
Ultrasound-guided percutaneous needle insertion is a standard procedure employed in both biopsy and ablation in clinical practices. However, due to the complex interaction between…
World Models for General Surgical Grasping
Hongbin Lin, Bin Li, Chun Wai Wong +3
Intelligent vision control systems for surgical robots should adapt to unknown and diverse objects while being robust to system disturbances. Previous methods did not meet these re…
