This paper describes the different types of steering mechanisms and benchmarks a method for the selection of a steering system. It also explains the step-by-step method of designing a variable Ackerman steering geometry. The research uses the knowledge of Ackerman and trapezoidal systems, turning radius estimation, steering effort calculation, and the RMS error tool to design and justify the policies selected. The result comprises a detailed flow for designing a variable Ackerman steering geometry along with a set of Matlab codes that are required for the calculation of turning radius, space, angles on inner and outer wheels, and many other parameters. This paper offers essential knowledge for those who are new to the field and an overview for those interested in steering design.
