While platforms with universal and Mecanum wheels are quite common, standard wheels have the advantage of robustness against uneven ground and slippage. This paper gives an overview on recent developments in the design of omnidirectional undercarriages with standard wheels and categorizes mechanical designs according to their holonomy. Furthermore, requirements for different applications are discussed and simple evaluation criteria are proposed that can be used to compare designs.","PeriodicalId":365579,"journal":{"name":"2018 25th International Conference on Mechatronics and Machine Vision in Practice (M2VIP)","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130726950","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 study made use of a linear stage device to accurately modify the distance between parts and devices. We aimed to evaluate the potential of atmospheric plasma treatment to improve the mechanical performance of 3D printing systems. 3D printed samples were generated by a Tier Time UPBox Fused deposition modelling printer. Thirty ASTM D638 Type IV dog-bone samples were generated. They were grouped into 6 categories corresponding to varied heights from the generated plasma, namely 36 mm (Sample 1), 30 mm (Sample 2), 24 mm (Sample 3), 18 mm (Sample 4), 12 mm (Sample 5) as well as an unprocessed Benchmark Sample. Optimal ultimate tensile strength occurred at 24 mm being 19.01 MPa whilst the surface quality of the samples experienced little change.","PeriodicalId":365579,"journal":{"name":"2018 25th International Conference on Mechatronics and Machine Vision in Practice (M2VIP)","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134289749","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}

Artificial muscles usually have compliant structure, light weight, or high power-to-weight ratio. However, they also expose many defects that caused by their structure or material, moreover they are not developed in line with muscle mechanics. Therefore, based on Hill muscle model, we proposed a novel tendon-sheath artificial muscle with slender structure and light weight, it can meet the requirements of robotic applications like exoskeleton. Moreover, a small clamper driven by electromagnet is developed in this paper for the switching control of muscle activation and inactivation. The clamper is designed for clamping wire rope with diameter of 1-2mm which refers to the inner tendon of the tendon-sheath mechanism, and the maximum clamping force is 800N. The clamping performance of the clamper was tested on an experiment platform. The experimental results illustrated that the small clamper can clamp the moving wire rope effectively. On average, it takes 230ms for the small clamper from receiving the control signal to starting clamping, and another 150ms is taken for fully clamping.","PeriodicalId":365579,"journal":{"name":"2018 25th International Conference on Mechatronics and Machine Vision in Practice (M2VIP)","volume":"74 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133071227","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 idea is to use the centroids and membership distributions obtained by applying the Fuzzy-C-Means algorithm (FCM) to define the mass function. The proposed method allows finding composite focal elements that represent the highest uncertainty and ambiguity. Experiments were conduced on multi-spectral and multi-temporal images for the purpose of change detection by integrating the proposed method of mass function estimation in a process of post-classification by DST. The proposed system of change detection is characterised by a multi-level of imperfection handling where the ambiguity is modelled firstly by FCM, then the uncertainty and the imprecision are handled in the step of mass function estimation. The effectiveness of the proposed methodology is demonstrated by applying it to find transformed region within two landsat images where we obtained high rates of classifications.","PeriodicalId":365579,"journal":{"name":"2018 25th International Conference on Mechatronics and Machine Vision in Practice (M2VIP)","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125300770","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}

Existing methods leverage on sophisticated microscope such as confocal laser scanning microscope or electron microscope may not be applicable for a portable setup. Staining of plant cell specimens, in order to improve visibility of boundaries, might affect the plant cell and also requires additional preparation work prior to acquisition which could be infeasible for on-the-fly applications. Conventional plant cell segmentation using watershed transform often results in over-segmentation, hindering the effectiveness of the method. Hence, we propose a thresholding method based on Otsu’s method, to retain majority of the image information to improve the success rate of the cell segmentation. The method is implemented on a leaf cellular image acquired from freshwater weed elodea. The region identified by the improved watershed transform can be further processed to locate the centroids of the cells. We experimented our method on images filled fully with plant cells and filled partially with plant cells. We also studied the impact of boundary definition of the image to our method.","PeriodicalId":365579,"journal":{"name":"2018 25th International Conference on Mechatronics and Machine Vision in Practice (M2VIP)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116819058","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}
