In gait training of post-stroke patients with LLEs, one of the main challenges is how to generate appropriate gait patterns from the sound leg to the paretic leg for different patients with varying walking speeds. In this paper, we proposed a Synergetic Gait Prediction (SGP) model for rehabilitation LLEs with..."} -{"title": "Organization and Understanding of a Tactile Information Dataset TacAct For Physical Human-Robot Interaction", "detail_url": "https://ieeexplore.ieee.org/document/9636389/", "author_list": ["Peng Wang", "Jixiao Liu", "Funing Hou", "Dicai Chen", "Zihou Xia", "Shijie Guo", "Peng Wang", "Jixiao Liu", "Funing Hou", "Dicai Chen", "Zihou Xia", "Shijie Guo"], "abstract": "Human touching the robot to convey intentions or emotions is an essential communication pathway during physical Human-Robot Interaction (pHRI).

Interpreting human touch gestures is a nuanced, challenging task with extreme gaps between human and robot capability.

To fully observe the system without changing the current configuration, a gyroscope and an accelerometer are attached to each link as dead-reckoning sensors. Observations of the dead-reckoning sensors are associated with the states of the multi-lin..."} -{"title": "Computationally Affordable Hierarchical Framework for Humanoid Robot Control", "detail_url": "https://ieeexplore.ieee.org/document/9636013/", "author_list": ["Koji Ishihara", "Jun Morimoto", "Koji Ishihara", "Jun Morimoto"], "abstract": "We propose a hierarchical control framework for generating versatile motions by a humanoid robot. The central feature of our framework is computational affordability: a large amount of computation time is allowable in the upper-level hierarchy. Consequently, whole-body trajectory optimization for a long time horizon becomes feasible. To ensure such affordability, a fast feedback loop is establishe..."} -{"title": "Water Surface Stability Prediction of Amphibious Bio-Inspired Undulatory Fin Robot", "detail_url": "https://ieeexplore.ieee.org/document/9636182/", "author_list": ["Zhenhan Chen", "Qiao Hu", "Yingliang Chen", "Chang Wei", "Shenglin Yin", "Zhenhan Chen", "Qiao Hu", "Yingliang Chen", "Chang Wei", "Shenglin Yin"], "abstract": "To solve the interference problems of wind and wave action and load movement when switching under water surface conditions in the marine environment, a study on the water surface stability prediction of the bio-inspired undulatory fin robot is carried out.
