In addition to the 7DOFs of the free upper limb, two passive DOFs were introduced to support the pectoral girdle protraction/retraction and elevation/depression, and ensure the instantaneous center of shoulder rotation is aligned with human. Furthermore, a Bowden-cable-based actuation was designed to reduce the whole weight and moment of inertia. Subsequently, to evaluate the performance of the proposed exoskeleton, the experiment of discrete point tracking was tested for elbow joint through the designed PID controller. Experimental results indicated that the designed PID control system could achieve stable feedback control. Thus, the proposed exoskeleton could realize the desired position accurately. This exoskeleton achieves the human-robot kinematic compatibility and precise position control, laying the foundation for the next step of continuous trajectory tracking control over the multiply joints.","PeriodicalId":123351,"journal":{"name":"Proceedings of the 3rd International Conference on Service Robotics Technologies","volume":"99 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-03-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125836659","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}

We prove that when facing multiple path branches, it is a necessary condition for optimal robot exploration to explore the branches connecting independent areas first, so we propose a local exploration strategy based on small areas priority. In order to realize this strategy, our method models lidar points and builds a prediction map covering more spatial information obtained by the sensor at the expense of accuracy. This method evaluates the potential explorable area of the unexplored space through ray-casting and the path tree, and decides which of the explorable path branches is the optimal choice in the local range. The method is compared to existing state-of-the-art methods in two corridor simulation scenes and three simulation scenes replicated from the real world. Experiment comparisons show that our method is more efficient in exploring space and closer to the global optimal trajectory.","PeriodicalId":123351,"journal":{"name":"Proceedings of the 3rd International Conference on Service Robotics Technologies","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-03-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125540541","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}

How to reduce shift impact and ensure shift smoothness is an important goal of synchronizer. This paper presents a novel synchronizer shift actuator controlled by proportional reducing valve, which can ensure the smoothness of shift, and the generated back pressure can effectively reduce the shift impact. In order to reduce the shift impact and complete the fast shift at the same time, the active disturbance rejection control (ADRC) method is applied, which can estimate and compensate the uncertainty of the system in real time, and improve the anti-interference ability and adaptive ability of the gear actuator. A simulation and test platform were built to verify the proposed control method. The results show that the proposed method can quickly complete the gear shift and effectively reduce the shift impact.","PeriodicalId":123351,"journal":{"name":"Proceedings of the 3rd International Conference on Service Robotics Technologies","volume":"435 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-03-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126105954","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}

Electric power plays an important role in daily life and industrial power consumption. Modern society is more and more dependent on electric power. As an important part of power system, distribution network distributes electric energy to all kinds of users through power facilities, so the reliable operation of distribution network is particularly important. The live working technology of distribution network can overhaul and test the power equipment through the robot without power failure. This paper studies and designs the appearance structure, hardware composition, software system, operation process and field test of the live working robot of distribution network.

But the fixed resolution setting of OctoMap restricts the environment expression ability and occupies large storage space. To overcome the restriction, an adaptive resolution OctoMap method based on point cloud density analysis is proposed. Firstly, the minimum circumscribed rectangle of the point cloud through PCA analysis. The minimum circumscribed rectangle of the point cloud is equally divided into N point cloud bounding boxes. A density analysis method is proposed to evaluate the environmental complexity of each point cloud bounding box. Finally, the resolution of the OctoMap is adaptively set based on the density analysis of the point cloud bounding boxes. Numerical experiments indicate that the proposed mapping method can self-adaptively adjust the resolution of Octotree map to express environment with various complexity, which effectively solves the contradiction between the environment expression ability and the mapping efficiency.","PeriodicalId":123351,"journal":{"name":"Proceedings of the 3rd International Conference on Service Robotics Technologies","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-03-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127412935","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}
