The problem such as folding of deformation displacement field and model degradation, all can lead to loss of registration accuracy. To address these problems, a deep learning-based unsupervised method(MulSc-Net) is proposed. On one hand, the MulSc-Net adopt a novel multi-scale registration strategy which can capture deformations at different scales with a larger receptive field via a fusion model of convolution and dilated convolution. On the other hand, an anti-folding constraint is introduced to ensure the continuity of displacement field, and a residual method is employed to prevent model degradation during training. In this work, the MulSc-Net model is evaluated on a lung CT dataset. The experimental results show that MulSc-Net can achieve better registration accuracy compared to current related methods.","PeriodicalId":220013,"journal":{"name":"2023 International Conference on Advanced Robotics and Mechatronics (ICARM)","volume":"75 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114678583","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

With the intent of providing a useful manipulator for robotic cell microinjection, this paper presents a novel complaint guiding mechanism for piezo-driven vibration cell microinjection. Mechanism design, kinematic modeling, parametric optimization, and simulation of the designed guiding mechanism are introduced in detail. The compliant guiding mechanism has a symmetrical and parallel connection structure with lumped compliance at its double-notch right-circle flexure hinges. Aiming at avoiding the resonance of the mechanism at actuation frequency, the response surface algorithm is utilized to optimize the dominant structural parameters of the designed guiding mechanism based on kinematic modeling with the pseudo-rigid-body method. The finite element simulation results show that the optimized compliant mechanism has the advantages of high off-axis stiffness and ideal working performance at the actuation frequency of 15 kHz, where the output amplitude of in-plane and out-of-plane lateral vibrations are diminished to 40% and 25% of the input lateral vibration amplitude respectively.","PeriodicalId":220013,"journal":{"name":"2023 International Conference on Advanced Robotics and Mechatronics (ICARM)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125530063","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This limits their practical applications since real-world environments are often dynamic and partially observable. To tackle these issues, vision-based reactive planning and control (V-RPC) is developed in this work. The V-RPC comprises two modules: offline pre-planning and online reactive planning. The pre-planning phase generates a reference trajectory over continuous workspace via sampling-based methods using prior environmental knowledge, given an LTL specification. The online reactive module dynamically adjusts the reference trajectory and control based on the robot's real-time visual perception to adapt to environmental changes.","PeriodicalId":220013,"journal":{"name":"2023 International Conference on Advanced Robotics and Mechatronics (ICARM)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125547766","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The correlation between the performance of motor task and brain activity in patients after stroke is warrant to investigate. In this current study, functional Near-infrared Spectroscopy (fNIRS) and surface electromyography (sEMG) were used to study the relationship between brain region activation and peripheral muscle contraction in different motor control tasks, and to explore the changes of information transmission between cerebral cortex and peripheral muscle in stroke patients. Three stroke patients were recruited and asked to perform elbow isometric flexion and extension on the affected side and unaffected sides. Blood oxygen concentrations in brain from fNIRS and sEMG signals in the biceps brachii (BIC) and triceps brachii (TRI) muscles were recorded simultaneously during different isometric contraction levels. Cortical activation and functional connectivity were used to measure information interaction in brain activity and the variation of elbow contraction under different exercise tasks was analyzed by root mean square (RMS) and co-contraction index (CCI) from sEMG signals. It was found that the RMS of the BIC and TRI on the unaffected side was greater than that on the affected side during both elbow isometric flexion and extension tasks. Meanwhile, in the 30% MVC condition, the CCI of the unaffected side of elbow isometric flexion and extension was lower than that of the affected side. The results showed that the activation of brain regions on the ipsilateral side was higher than that on the contralateral side, especially the motor cortex and the prefrontal cortex. Meanwhile, the results of functional connectivity were lower from ipsilateral than those on the contralateral side. In this study, the changes of blood oxygen in the brain and the changes of sEMG signal have a same trend of synchronization during motor tasks. This finding provides a basis for further exploration of the mapping relationship between brain activity and motor task performance in stroke patients, and can guide the rehabilitation intervention of motor function in stroke survivors.","PeriodicalId":220013,"journal":{"name":"2023 International Conference on Advanced Robotics and Mechatronics (ICARM)","volume":"73 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114190759","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In addition, for such robots, the mass of the heavy leg significantly impacts the ground reaction force (GRF) distribution and observation in the traditional control framework. This paper presents a GRF-Iess locomotion control framework for HQR based on five individual floating-base dynamics, fully considering the mass of legs and the coupled influence between the body and legs. We disassemble the full dynamics of the HQR into five spatially rigid parts with floating bases. The interaction effect between the body and legs is assumed to be a virtual spatial force (VSF), performing as the body's driving force and the loading force of the legs, which is obtained through the Nonlinear Disturbances Observer (NDOB). To realize the spatial trajectory control of the body, we utilize Quadratic Programming (QP) to solve the optimal VSF distribution on the body's hip joints. Furthermore, we employ Position-based Impedance Controllers (PIC) to build a VSF control loop to ensure that each grounded leg provides sufficient VSF to drive the body without slippage. Verification results show the promising locomotion control ability of the proposed framework for HQR.","PeriodicalId":220013,"journal":{"name":"2023 International Conference on Advanced Robotics and Mechatronics (ICARM)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128535739","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
