A Stewart platform is a parallel kinematic structure consisting of a moving platform connected to a fixed platform by 6 synchronously acting linear actuators.
This design enables an object placed on the moving platform to be moved with 6 DDL (degrees of freedom). In other words, the hexapod can move an object in 3 translations (Tx, Ty, Tz) and 3 rotations (Rx, Ry, Rz); any combination is possible.
This technology, derived from mechatronics, is particularly well suited to applications requiring fine, complex positioning along several axes positioned in any reference frame. In this way, an object placed on the moving table can be positioned, adjusted and assembled simply and easily.
