A Stewart platform is a type of parallel manipulator that has six prismatic actuators, commonly hydraulic jacks or electric linear actuators, attached in pairs to three positions on the platform's baseplate, crossing over to three mounting points on a top plate.
Abstract render of a Hexapod platform (Stewart Platform) A parallel manipulator is a mechanical system that uses several computer-controlled serial chains to support a single platform, or end-effector. Perhaps, the best known parallel manipulator is formed from six linear actuators that support a movable base for devices such as flight simulators.
An example of a Stewart Platform, a spatial mechanism. A mechanism in which a body moves through a general spatial movement is called a spatial mechanism. An example is the RSSR linkage, which can be viewed as a four-bar linkage in which the hinged joints of the coupler link are replaced by rod ends, also called spherical joints or ball joints ...
Elon Musk took aim at the U.S. Agency for International Development this weekend, gaining access to top secret documents, though at first his DOGE was denied the access.
Cartesian manipulators are driven by mutually perpendicular linear actuators. They generally have a one-to-one correspondence between the linear positions of the actuators and the X, Y, Z position coordinates of the moving platform, making them easy to control. Furthermore, Cartesian manipulators do not change the orientation of the moving ...

Ampelmann E-type on the platform supply vessel NORMAND JARSTEIN. Accessing any offshore structure can be problematic due to the movement of a vessel compared to the structure. The Ampelmann eliminates any relative motion by taking instant measurements of the ship’s motions and then compensating movement using a Stewart platform. This means ...
