Complex HRI tasks are often embodied in robots that are jointly constrained by task space and joint space. In the field of Imitation Learning, scholars have explored the topic of joint constraints from task space and joint space, but there are few relevant studies in Human-Robot Interaction. In this paper, based on the Interaction Primitives framework (a HRI framework), we propose an interaction inference method that first generalizes the robot's movements in two spaces synchronously and then probabilistically fuses the two movements based on Bayesian estimation. This work was validated in the task that the robot follows a human handheld object, and the inference errors (RMSE and MAE) of the method are smaller in both task space and joint space than in IP using only singlespace inference.","PeriodicalId":151112,"journal":{"name":"2022 IEEE International Conference on Robotics and Biomimetics (ROBIO)","volume":"3 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":"130809336","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}

Traditionally, position-based control methods are adopted by video satellite for target tracking, but these methods are not capable of tracking non-cooperative maneuvering target. This paper proposes an image-based visual tracking control method together with an observer of the target position. Firstly, the reference image tracking error and angular velocity error are derived on the basis of the estimated target position. Then the observer of the target position is proposed, and the position of the observed target is estimated based on the projected coordinates and visual velocity information on the image. Finally, based on the reference attitude error and the observer, the visual tracking controller is proposed to keep the projection of the moving target at the desired image center. Simulations verify the effectiveness of the proposed visual tracking controller for fast maneuvering targets.","PeriodicalId":151112,"journal":{"name":"2022 IEEE International Conference on Robotics and Biomimetics (ROBIO)","volume":"1 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":"130915108","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 configuration has two operating modes and can provide three degrees of force feedback. Secondly, a hybrid force/position master-slave control system based on the kinetic model force feedback method is built, which can realize incremental master-slave control, variable proportional control, force feedback, and other functions. Finally, the positional accuracy, gravity balance effect, and force feedback performance of this master manipulator are verified through experiments. Experiments show that the average position error of this novel force feedback master manipulator is 1.18 mm, the average attitude error expressed in terms of Euler angles is 0.83°, and the maximum feedback force that can be provided is 12.1 N, which satisfies the requirements of ultrasonic scanning.","PeriodicalId":151112,"journal":{"name":"2022 IEEE International Conference on Robotics and Biomimetics (ROBIO)","volume":"85 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":"132852736","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}

However, the high-temperature production process (about 1,450 °C) emits intense infrared and visible lights that will blur the edge and hinder the accurate calculation for the diameter of the crystal ingot. In this paper, the aura phenomenon caused by high-temperature radiation is deliberated and the Sigmoid function is discovered to best fit the luminance distribution along the normal direction of the edge. Thus, a sub-pixel edge detection method based on Sigmoid fitting is proposed for high-temperature objects, such as the single silicon crystal. The method first extracts the coarse edge of the object, then the luminance distribution on the normal direction of the coarse edge is fitted to the Sigmoid function. Mathematical analysis points out the location of the precise sub-pixel edge is closely related to the parameters of the fitted Sigmoid function. Real-world experiments of applying our proposed method and other different methods in the measurement system are performed. Comparison results prove superiority of our proposed method in accuracy and robustness.","PeriodicalId":151112,"journal":{"name":"2022 IEEE International Conference on Robotics and Biomimetics (ROBIO)","volume":"315 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":"132878802","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 future states of manipulators are important for learning the inverse dynamic model of manipulators, which was ignored in past research. In this paper, the BiLSTM network was chosen for learning the inverse dynamic model of manipulators. The future desired position and velocity of manipulators are as the input for backward propagation. The actual position and velocity of manipulators are as the input for forwarding propagation. Furthermore, to improve the accuracy of the model, each joint of the manipulator is trained separately. Finally, comparison experiments are conducted using back-propagation (BP), long short-term memory (LSTM), gated recurrent unit (GRU), and the proposed method on the UR5 manipulator. The experimental results show that the proposed method can achieve higher accuracy and faster convergence of the inverse dynamic model.

The elastic limit of superelastic NiTi is much larger than that of ordinary materials, and it no longer obeys Hooke's law. Axial compression of pri-mary backbone is extremely small and has been found to have an important impact on the external force sensing accuracy of continuum robot using super elastic nickel titanium alloy backbones. Firstly, the dynamic model of the continuum robot is revised and the general formula for estimating the tension of multiple driving cables (more than 3) of the continuum robot in the presence of external forces are given. The value of the elastic modulus estimated online by quasi-static conditions is used with other generalized coordinates as the input of the axial compression intrinsic sensing algorithm, so as to obtain the estimated result of real-time axial compression. The method provides a feasible path for predicting the axial deformation of continuum robot while allowing for fast computation. Experiments present the results of intrinsic sensing of axial compression in the cases of three different driving forces.","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":"134485609","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}
