Stewart platform

grabcad

A Stewart platform, a parallel robot type, utilizes six prismatic actuators, typically hydraulic jacks, mounted in pairs to the base and crossing over to three points on the top plate. This allows devices on the top plate to move in six degrees of freedom, including x, y, z (lateral, longitudinal, and vertical) linear movements as well as pitch, roll, and yaw rotations. It is also referred to as a "six-axis" platform.
