Stewartplatform
The Stewart platform, named after its inventor, Dr. Richard Stewart, is a type of parallel robot or kinematic mechanism used for precise motion control in multiple degrees of freedom. Introduced in the 1960s, it is a six-degree-of-freedom (6-DOF) mechanism capable of positioning and orienting an end-effector (such as a tool or sensor) in three-dimensional space with high accuracy. The platform consists of a central moving platform connected to a fixed base via six adjustable struts, each controlled by an actuator. These struts are arranged in a specific geometric configuration, typically following a hexapod or tripod pattern, allowing for complex movements while maintaining rigidity.
The Stewart platform is widely used in applications requiring precise positioning, such as aerospace testing, medical
The design of the Stewart platform allows for a compact structure with a large workspace, making it
Variations of the Stewart platform exist, including the Gough-Stewart platform, which is a more generalized form
