This paper presents a RAM process simulation and implementation method. A virtual part with design geometry and building bead from Fused Deposition Modeling (FDM) technology is presented in a simulation software platform. The RAM path and bead size can be tuned based on path, FDM equipment, such as robot model, extrusion head types, and other building parameters. Similarly, a Wire and Arc Additive Manufacturing (WAAM) system is setup for cladding applications. Some of the research results from both FDM and WAAM are presented and discussed. Finally, related future work in this direction is proposed.","PeriodicalId":185881,"journal":{"name":"2018 WRC Symposium on Advanced Robotics and Automation (WRC SARA)","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125603238","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 objectives are to maximize the number of rescued survivors, minimize the waiting time of survivors, and minimize the total traveling distance of robots, with priority from high to low. In this paper, a cluster-first strategy is proposed, which builds upon existing consensus-based distributed task allocation algorithms. The basic idea is that assigning a group of tasks that are clustered to each other to a robot is more likely to result in an efficient schedule, thus reducing the waiting time for survivors and the robots traveling distance, which in turn may increase the number of people rescued. Each robot updates its cluster at the beginning of each iteration and prioritizes adding survivors in the cluster to its rescue plan. Simulated rescue scenarios are used to evaluate the performance of the proposed strategy. The proposed strategy is applied to two representative consensus-based distributed algorithm, the consensus-based bundle algorithm (CBBA) and the performance impact (PI) algorithm. Experimental results show the applicability and the outstanding performance of improving solution quality of the proposed strategy.","PeriodicalId":185881,"journal":{"name":"2018 WRC Symposium on Advanced Robotics and Automation (WRC SARA)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125277658","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}

Based on the comprehensive analysis of the evolution trend of robot bionic legs at home and abroad, the concept and design principles of smart dexterous legged legs with single degree of freedom are proposed. Explore how to achieve complex leg movements through agile and efficient mechanical mechanism design. Robot bionic legs with single degree of freedom which are belong to multi links are studied from 4 bars, 6 bars to 8 bars, and topological graph and kinematic chain of the 8 bars with single degree of freedom is given. Through theoretical analysis, virtual prototype simulation and real prototype experiment, the feasibility and superiority of the 8- bar bionic leg with single DOF are verified.","PeriodicalId":185881,"journal":{"name":"2018 WRC Symposium on Advanced Robotics and Automation (WRC SARA)","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127160641","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 augmented reality technology can display the swarm robots operating and environment in front of the operator, which reduces the operator’s cognitive complexity of remote robots. What’s more, the gesture recognition technology for natural interaction improves the naturalness of the proposed interaction method. The swarm robots coordination control rules are designed for that the difficulty in operating will not increase as the size of swarm robots increases. Simulations and experiments are performed to demonstrate the validity of the method. And the proposed method is verified with real robots.","PeriodicalId":185881,"journal":{"name":"2018 WRC Symposium on Advanced Robotics and Automation (WRC SARA)","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126820810","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}
