Stewart platform

From Free net encyclopedia

A Stewart platform is a kind of manipulator using an octahedral assembly of struts. A Stewart platform has six degrees of freedom (x, y, z, pitch, roll, & yaw).

Stewart platforms have applications in machine tool technology, crane technology, underwater research, air-to-sea rescue, flight simulation, satellite dish positioning, aircraft simulators and telescopes.

James S. Albus of the National Institute of Standards and Technology (NIST) has developed a crane, known as RoboCrane®, which uses the Stewart platform technology.

Geodetic Technology trademark "hexapod" for a Stewart platform in a machine tool context.

The Stewart platform was first reported in a paper by D. Stewart in 1965.
