Pantographic blocks are metamaterials made of a finite number parallel pantographic sheets interconnected by cylindrical pivots. In this paper, block subjected to 3-point flexure, where the prescribed displacements plane, shows essentially monoclastic deformation (i.e., one principal curvatures top surface is found be negligible wrt. other one). modeled herein with second gradient 3-dimensional...

We propose an interactive edit web system, that is, users can edit and revise documents cooperatively and interactively. The Ie-web is constructed based on conceptions of special issue edit and pantographic issue edit. The goal of this study is not only developing cooperative document making system by many users, but research paper making system by mentors and other students. In recent years, c...

HAL is a multi-disciplinary open access archive for the deposit and dissemination of scientific research documents, whether they are published or not. The documents may come from teaching and research institutions in France or abroad, or from public or private research centers. L’archive ouverte pluridisciplinaire HAL, est destinée au dépôt et à la diffusion de documents scientifiques de niveau...

In the growing field of rehabilitation robotics, the modelling of a real robot is a complex and passionate challenge. On the crossing point of mechanics, physics and computer-science, the development of a complete 3D model involves the knowledge of the different physic properties, for an accurate simulation. In this paper, it is proposed the design of an efficient three-dimensional model of the...

The development of a practical mobile robot system for mechanization of humanitarian demining tasks such as sensing/verification and/or clearance of anti-personnel landmines is close to be completed. The system proposed by Hirose group at Tokyo Tech is a simple but effective solution that consists of a pantographic weight-balanced manipulator mounted on top of a mobile platform. A practical and...
