WebA parallel robot is a mechanical device that supports a single base or end-effector by using multiple computer-controlled serial chains. The most well-known parallel manipulator consists of six linear actuators that sustain a movable foundation for applications like flight simulators. In other names, it is called the Stewart platform, also ... WebTo clearly describe the motion of the moving platform, the coordinate systems are illustrated in Figure 2. The coordinate system (BXYZ) is attached to the fixed base and …

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. All 12 connections are made via universal joints. Devices placed on the top plate can be moved in the six degrees of freedom in which it … WebMay 1, 2015 · The research of forward kinematics of the Stewart platform has experienced four stages. The first stage: special configuration manipulators. A i and B i (i = 1…6) denote the joint points on the base platform and mobile platform, respectively.
