To segment gait phases of human locomotion tasks, such as level walking and stairway walking, ground reaction force(GRF) data during walking are collected. This paper presents a fuzzy logic inference (FLI) technique tuned by particle swarm optimization (PSO), which is used to find optimal triangular membership functions. To discriminate flexion and extension of swing leg, ground reaction force of...
Freehand 3D US-guided robot-assisted percutaneous surgery system, presently under development in our laboratory, has the potential to overcome some drawbacks of current conventional clinical interventions. The robot is commanded to insert accurately the needle into the target in patient's body according to planned path in the 3D model reconstructed by freehand 3D US by several separate steps, one...
