Abstract
The SRSPM is the most widely used and hence the most important Gough-Stewart platform configuration for various practical applications. Hence design for geometrical parameters to achieve optimal performance is of considerable interest. This paper presents a search based algorithm to determine the optimal geometrical parameters for the SRSPM for given desired workspace specifications. We have used the knowledge of the generic shape of the workspace as revealed by previous studies, and a few fundamental observations on the effect of varying different geometrical parameters on the geometry of the workspace to design an algorithm to solve our design problem. Two main observations used are - the size of the end effecter determines what volume of the reachable workspace is actually the region over which the tool is orientable in any desired directions and the actuated length can be increased to have a new increased workspace volume.
