The robot's traverse ability varies due to its structure, topology, and locomotion controller. The existing motion planner rarely considers the robot's traverse ability, causing higher failure risk when it gives motion commands that do not match the robot's capability. In this paper, we present CapPlanner, a hierarchical motion control and planning system which can do long-range locomotion control and planning according to the learned traverse capability of the robot in different topologies. It consists of two layers, the bottom-level controller computes the trajectory of the body and the feet according to the terrain, local target and current feets' positions. Besides, it controls the motors to track the calculated trajectory. The top-level controller learns the traverse ability of the robot with its bottom-level controller by simulating locomotion tasks on various terrains and in different topologies. Hence our CapPlanner can guide the robot to reach a long-term destination with a much higher success rate. In the experiment, we test CapPlanner in simulation and on our real hexapod robot, Qingzhui. The results show that CapPlanner is able to accomplish long distance and tough terrain locomotion planning for hexapod robot.","PeriodicalId":151112,"journal":{"name":"2022 IEEE International Conference on Robotics and Biomimetics (ROBIO)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126994791","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}

A discrete-time optimal controller based on auto disturbance rejection control technology is used to realize fast response of output magnetic field to current. We have designed a closed-loop controller based on position servo. The control system consists of closed-loops of direction and position. As the sampling frequency of vision based position feedback of microrobot is not high enough, the actual position cannot be transmitted to the control system in time. Kalman filter algorithm is used to predict the position of microrobot in the movement process to improve the accuracy of control. Combined with the magnetic drive device and the proposed microrobot control method, simulation and experiment are carried out to verify the proposed scheme.

Besides physical parameters like tidal volume or respiratory rate, biomedical signals like electromyography (EMG) signals can be a potential candidate for breathing activity monitoring. In this work, we propose a novel scheme for breathing activity pattern recognition by fusing features extracted from both EMG and acceleration signals. The EMG signals and acceleration signals during four breathing activities usually used in our daily life, including normal breathing, fast breathing, coughing, and deep breathing, are captured. The raw data is preprocessed, feature extracted by several hand-crafted features, and pattern classified. The performance of five EMG feature sets, five acceleration feature sets, and two machine learning algorithms are evaluated. The best result achieves an accuracy of 82.20% using an EMG feature and an acceleration feature with a support vector machine (SVM) classifier. It shows that fusing EMG and acceleration data is better than EMG signals alone or acceleration signals alone, and it also raises the problem of finding the best features to reach higher performance. To the best of our knowledge, this is the first time that EMG signals are combined with acceleration signals for human breathing activity classification. The proposed approach is effective and explores a new way of human breathing monitoring.","PeriodicalId":151112,"journal":{"name":"2022 IEEE International Conference on Robotics and Biomimetics (ROBIO)","volume":"64 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121665149","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}

Aiming at the above problems, the advantages and disadvantages of pose estimation schemes of binocular cameras based on different algorithms are compared and analyzed through data sets experiments and real environment experiments. The Error-State Kalman Filter (ESKF) based fusion framework and formulas are proposed. The comparison fusion experiments using internal and external sensors are conducted with angular velocity compensation and without.

According to the CAD file information, the 3D model of an industrial part is established. Then, an offline template library is obtained by the 3D model under different observation views, to reduce the actual online measurement time. The similarity function between the image and the template is established by a Canny-based improved Chamfer distance matching algorithm. The Chamfer distance image is divided into four layers by using the direction angles of the edge gradient, to improve the sensitivity of the matching function. Genetic algorithm (GA) is used to search for the optimal matching result, which combined with the hill-climbing method to make the searching process converge quickly. The experimental results show that our proposed method can measure the targets with known complex shapes in a 3D working environment, with the position error is within 2mm and the rotation error is within 2°. For dynamic parts, our proposed method can achieve fast matching, and the matching is applicable to different dynamic target parts, the model matching is only related to the shape of the part.","PeriodicalId":151112,"journal":{"name":"2022 IEEE International Conference on Robotics and Biomimetics (ROBIO)","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132508715","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}

Adaptive step-size adjustment is applied in NR and dynamic scale coefficient in cost function brings convergence to the steady state equation of component model. To reduce the difficulty of deciding the initial status, typical mutation mechanism is utilized to enhance the exploitation characteristic of Pigeon-Inspired Optimization, which is effective in searching for the suitable initial value of NR method.

However, most existing exoskeleton devices for hip rehabilitation have an anthropomorphic structure. Misalignment between the mechanical and planted prothesis center is a problem that can cause additional stress in the hip for anthropomorphic exoskeletons, which are thus not applicable to THA rehabilitation training process. Also, the parasitic force due to the cable pulling of soft exoskeletons is also regarded as a shortcoming for users. To address these limitations and to provide training assistance for THA patients for better recovery, a novel hip exoskeleton with parallel structure is presented in this paper. The proposed exoskeleton has a remote actuation and Cable-conduit transmissions and is hence light in weight and can provide bidirectional assistive/resistive torque in the hip without generating stress in the hip, which is significant for THA patients having weak and sensitive planted hip joints. A controller is presented for a stable and safe human-machine interfacing during training with desired assistance delivered. Experiment results based on a benchmark platform verify the performance of the proposed exoskeletons system.","PeriodicalId":151112,"journal":{"name":"2022 IEEE International Conference on Robotics and Biomimetics (ROBIO)","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134093461","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}
