| Abstract | Relevant works on the design of spherical parallel robots (SPRs) are mostly for conceptual design. The conceptual design of a SPR considers kinematic parameters and variables to describe the motion transformation between joints and the end-effector. For example, the Denavit-Hartenberg (D-H) notation with four kinematic parameters is used to represent the spatial relations of two motion axes with no consideration of the physical embodiment between the two axes. We call the design parameters involved in the conceptual design phase as conceptual design parameters (CDPs). In contrast, embodiment design concerns the specifications of links and kinematic pairs in terms of their geometrics, volumes, spatial arrangements and dynamic behaviors. Accordingly, we call the design parameters in the embodiment design phase as embodiment design parameters (EDPs). As far as a robotic design is concerned, a critical challenge of embodiment design is to sustain the workspace obtained in conceptual design based on CDPs. Actual geometries of objects might cause the interferences among physical objects in an embodied robot. In this paper, the conceptual design of a SPR is assumed to be known, the embodiment design of a SPR is focused to minimize the workspace loss caused by EDPs. We propose three principles to guide the embodiment design of the SPR, and we apply the general algorithm (GA) for interference check based on the proposed principles. A case study of the embodiment design of a SPR is provide to illustrate how the principles are used to maximize the robot workspace at the stage of embodiment design. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
