With the help of high-level image description features provided by CNN, the deep architecture models perform significantly better than state-of-the-art solutions that use traditional hand-crafted features. In this paper, we concentrate on the scene recognition problem especially for changing environments, such as view angle changes, illumination variations, occlusion, different weather conditions and seasons. We propose a new scene recognition system using the deep residual convolutional neural network (ResNet) as the image feature extractor. The initial feature vectors are chosen from specific layers of the network and after a series of post-processes, we can obtain the final image descriptor vectors for scene similarity measurement. The performance of our proposed methods is evaluated on four popular open datasets by comparing it with the classic FabMap method and some other deep learning-based methods.","PeriodicalId":270665,"journal":{"name":"2019 4th International Conference on Robotics and Automation Engineering (ICRAE)","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116569922","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 mathematical model between intersection coordinate and tubesheet thermal deformation was established. The steady and accuracy of this method in the detection of tubesheet thermal deformation were verified. The static detection error was no more than 0.006 mm. The maximum thermal deformation of tubesheet in our experiment was no more than - 2.6 mm.

But snake robot has a high requirement for the real-time of the control framework since it has several modules which contain a variety of sensors. To solve the problem, the control frame based on the Xenomai real-time system is developed by inserting a patch to the kernel and the real-time performance can be further enhanced by priority scheduling. The proposed control framework of the snake robot is applied to deal with the non- real-time communication thread with ROS packages and the real-time communication thread with the joint controller. So the application programs based on the proposed control framework can realize the multi-task function and be compatible with the ROS system. At last, the experiments validate that the control framework can control the hardware of the snake robot efficiently.","PeriodicalId":270665,"journal":{"name":"2019 4th International Conference on Robotics and Automation Engineering (ICRAE)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134195903","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, current designs for electromagnetic artificial muscles only satisfy either great force to stroke ratio or great force to weight ratio or low power consumption but none has achieved all three. This study aims to design an electromagnetically driven magnetic coupled artificial exoskeletal muscle that can exhibit better force to stroke, force to weight and lesser power. As a result, the prototype was able to attain a force to stroke ratio of 0.333 N/mm, force to weight ratio of 18.18 N/kg and can consume a maximum of 53.1 Watts of power. Compared to elastic actuator, the prototype was able to satisfy all three advantages of an electromagnetic artificial muscle.","PeriodicalId":270665,"journal":{"name":"2019 4th International Conference on Robotics and Automation Engineering (ICRAE)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129173455","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 system is developed based on an UAV equipped with a camera to be deployed from a ground station and patrols the parking lot through a fixed flight path with a pre-defined waypoints mission to capture all vehicles' license plate that were parked in the parking lot. The images were then downloaded from the UAV for license plate detection and recognition via Google Cloud Vision. Postprocessing was performed to increase the detection accuracy of license plates. The detected license plates and their respective timestamp were logged in the database for parking fee charging purpose.

Even though NDE (Non-Destructive Evaluation) technology is developing rapidly, how to inspect pipelines buried underground effectively is still a problem remaining unsolved. The reason is that there is no developed equipment which can pass through pipelines carrying NDE sensors and provide the circumstances under which testing tasks can be done properly. This paper designs a practical robotic system called “Inspector” for in-pipe inspection of underground urban gas pipelines using PLC, which stands for power line communication. Inspector is able to pass through different obstacles (bends, elbows and tees) at a pipe network, climb in vertical pipes and recover from capsizing. Except for that, the robot can also conduct inspection tasks and show conditions of pipes clearly. Besides, this paper proposes a self-control strategy using laser range finders, which are used to detect road conditions ahead of Inspector. With the efforts of all the team members, a prototype of the robot system has been completed, qualified with the functions mentioned above.","PeriodicalId":270665,"journal":{"name":"2019 4th International Conference on Robotics and Automation Engineering (ICRAE)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133815369","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 multiple learning iterations, the robot can determine the reference. After estimating the reference, the robot can execute the tasks independently.
