In this research a web-based symbolically assisted dimensional synthesis system of the planar pin jointed multi-link mechanism is presented. Triangular geometric unit is used iteratively to calculate the node coordinates of the linkage system. Real-coded Genetic Algorithms are used to search for the optimal solution of the path generation problem of linkage which can consist of any number of planar pin jointed links. Systematic formulation of the linkage analysis will be enabled according to the user's planar linkage configuration which can be input directly on the web browser canvas area. Once the system definition is completed, all relevant equations can be derived and executed automatically. Email will be sent to the user for examination of the resulting animation and convergences results.
