A two-stage transmission mechanism is proposed, aiming at reducing the volume and mass of caudal peduncle. Benefited by it, both volumes and mass of moving parts can be reduced to allow higher swing frequency. At the same time, two joints driven by two motors ensure the flexibility of steering. The robotic fish achieves a maximum speed up to 1.65 body lengths per second (BL/s) and a minimum turning radius less than 0.35 body lengths (BL), based on the open-loop control designed by Central Pattern Generator (CPG) method. Furthermore, a yaw control is proposed to maintain course angle at high swimming speed, and simulation in Automatic Dynamic Analysis of Mechanical Systems (ADAMS) software reveals the effectiveness. The results show that the proposed yaw control method can regulate the fluctuation of anterior body to desired range but without compensation of sideways drift.","PeriodicalId":121822,"journal":{"name":"2019 IEEE International Conference on Robotics and Biomimetics (ROBIO)","volume":"1991 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131312650","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 this paper, a novel hand-eye coordination algorithm is proposed for the robot -assisted minimally invasive surgery (RMIS). Firstly, a novel cascade-calibration (CC) algorithm structure is proposed to determine the pose relationship between the robot laparoscope arm coordinate system and the robot instruments arm coordinate system. A hand-eye coordination algorithm is also proposed, which provides accurate master-slave control and improves the surgical operation room (OR) efficiency. We validate the proposed algorithm through two experiments with our minimally invasive surgical robot system. Our experiments demonstrate that the proposed method is competitively effective to induce the hand-eye coordination for the RMIS.","PeriodicalId":121822,"journal":{"name":"2019 IEEE International Conference on Robotics and Biomimetics (ROBIO)","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128866811","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}

It exploits the Euclidean distance constraint any three feature points in a submap can form. A 2D graph SLAM system using TF to close loops is also developed.

Firstly, all kinds of information mentioned in user instructions are extracted through natural language processing, including object information, namely structured data and environment information, namely unstructured data. For structured data, it is mapped to the predefined ontology knowledge base to obtain its location attributes and state attributes, and then obtain service instructions. Adaptive fuzzy Petri net (AFPN) is constructed based on fuzzy rules of temperature, humidity and other environmental information. The unstructured data is taken as the input parameter of AFPN, and the service instruction deduced as the output. Then, according to the user’s needs, the network weight can be continuously adjusted. If the user does not mention the environmental information, the environment information is periodically detected by the sensor, and the service instruction reasoning of the unstructured data is performed. Finally, back propagation neural network (BPNN) is introduced to combine the service inference of two kinds of data to eliminate the heterogeneity of different service instructions. Experimental results show that the model can provide different personalized services for users’ preferences.","PeriodicalId":121822,"journal":{"name":"2019 IEEE International Conference on Robotics and Biomimetics (ROBIO)","volume":"10 9","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120988912","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}

Accurate image alignment is needed and can be provided by 2D-3D registration by bringing a pre-operative 3D image and intra-operative 2D image into the same coordinate. In this work, we propose a novel method to register 3D volume with multi-view 2D images. Based on the Branch and Bound algorithm, the method can globally search the optimal pose and find the correspondence. Compared to the single-view setting, the multi-view 2D image information can speed up the searching. Extensive experiments are conducted to evaluate the effectiveness of the proposed method.

This paper introduces a 6-DOF bipedal leg-wheeled robot SR600, which has two actuated wheels at the end of the robot shanks, and achieves its balance and locomotion through wheel-driven approach. SR600 is mainly composed of five parts: a waist, two thighs, and two shanks with wheels. It is modeled as a variable-structure wheeled inverted pendulum and we derived its kinematics model based on the center of gravity constraint. Control strategies for balance and locomotion of SR600 are handled by proportional integral differential (PID) controllers.
