Sensitivity analysis of a new model of Stewart platform

Abstract

In this article, we introduce a new model of the Stewart Platform robot with rotary servo motors that is very cheap to build. First of all, studied a kinematic of the Stewart Platform, and then, with a simple geometric analysis, we’ll find the angles of servo motors for a specified position. Because of using the angular or rotational Servo motors in this model, sensitivity analysis is a crucial point. After sensitivity analysis of the model, we show the sensitivity level of a type of rotary servo in different coordinates x, y, and z.
