This microrobot is an evolutionary improvement of a previous microrobot utilizing microassembly of out-of-plane compliant mechanical structures. The original AFAM was a microrobot driven by two coupled in-plane MEMS X-Y stages, through an epoxied cable to an out-of-plane assembled arm. In this paper, sAFAM was designed to replace the cable traction system with an unibody arm that can be assembled into the in-plane X-Y stages, which simplifies the assembly process complexity and improves the microrobot precision. The proposed structure was simulated with finite element analysis (FEA), resulting in a $22mu mtimes 47mu mtimes 18text{S}mu m$ workspace, appropriate concentration of stresses during actuation, and reduced motion coupling between the microrobot degrees of freedom. Fabrication and assembly processes are discussed and demonstrated experimentally, and results closely match simulations. sAFAM has the potential to be used as an assist $mathbf{micro}/mathbf{nano}$ manipulation tool in the scanning electron microscope (SEM) or the atomic force microscope (AFM).","PeriodicalId":118389,"journal":{"name":"2018 International Conference on Manipulation, Automation and Robotics at Small Scales (MARSS)","volume":"89 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121979070","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}

Future consumer products, medical devices and manufacturing processes require sensing and actuation systems with high count and density of individual transducer units. Such systems can be addressed as distributed transducers. Building distributed sensing and actuation systems with conventional transducers is economically unaffordable, and an alternative solution is needed. In this work we propose and study a methodology to build such distributed sensor and actuator systems from soft bending smart material transducers. Individual transducer units can be separated from the planar material substrate by cutting and etching techniques, and transducer counts and densities are only limited by the available smart materials and equipment. In this study we use laser ablation techniques to separate individual transducer units from the ionic polymer-metal composite (IPMC) sheets, and produce translational actuation units on the bending material substrate. IPMCs are manufactured in-house, different bending structure geometries are studied, and four different designs of the em-scale translational platform units are realized and validated experimentally. The results demonstrate that it is possible to etch and cut a multitude of actuation units into planar bending smart material transducers, that bending actuation can be used to realize translation, and that the designs can be further miniaturized. Therefore, bending smart materials can be utilized to build monolithic distributed transducers.","PeriodicalId":118389,"journal":{"name":"2018 International Conference on Manipulation, Automation and Robotics at Small Scales (MARSS)","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122648501","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 work is motivated by the emerging field of multifrequency atomic force microscopy (AFM) which involves the excitation and/or detection of several cantilever modes at once. Unlike other operating modes, multifrequency AFM allows the tracking of the sample topography on the fundamental mode while simultaneously acquiring complimentary nanomechanical information on a higher mode. However, higher modes of conventional rectangular tapping-mode cantilevers are usually in the MHz regime and therefore impose severe restrictions on the direct controllability of these modes. To overcome this limitation, an optimization technique is employed which is capable of placing the first five modes within a 200 kHz bandwidth.","PeriodicalId":118389,"journal":{"name":"2018 International Conference on Manipulation, Automation and Robotics at Small Scales (MARSS)","volume":"126 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126276373","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}

Second, we demonstrate manipulation of the microbeads using microrobotic sperm under the influence of controlled magnetic fields. Our teleoperation manipulation trials show that the microrobotic sperm swims at an average speeds of 0.16 and 0.035 body-Iength-per-second during collision-free locomotion and manipulation, respectively.
