Modeling and Control of a Pneumatically Driven Stewart Platform
Electrically driven Stewart platforms are used in the field of machine tooling and robotics, where very accurate positions have to be reached associated with heavy loads. In this paper we present a pneumatically driven Stewart platform powered by fluidic air muscles. Due to the elasticity of the muscles and air as driving medium, the robot is predestined for applications where compliance plays ...
متن کاملA Stewart Platform Lunar Rover
A lunar version of the Robocrane is being developed at the Robot Systems Division of the National Institute of Standards and Technology (NIST) to address the needs of NASA researchers. The NIST robot, called ROBOCRANE, has three-pairs of rigged legs instead of actuators to create a gantry. The legs are joined in a Stewart Platform configuration providing a means for canceling out rotations norm...
متن کاملDynamic analysis and control of a stewart platform manipulator
The Stewart platform is a six-axis parallel robot manipulator with a force-to-weight ratio and positioning accuracy far exceeding that of a conventional serial-link arm. Its stiffness and accuracy approach that of a machine tool yet its workspace dexterity approaches that of a conventional manipulator. In this article, we study the dynamic equations of the Stewart platform manipulator. Our deri...
متن کاملModeling, simulation, and control of a hydraulic Stewart platform
This paper describes the modeling, simulation, and control of an inverted, ceiling-mounted Stewart platform, designed to be a one-person motion simulator. The dynamic equations of the Stewart platform are derived using the virtual work principle. It is shown by simulations that the leg dynamics can be neglected. A model of the electrohydraulic actuator is derived and then veri ed using experime...
متن کاملError Analysis of a Stewart Platform
The use of parallel structures, such as a Stewart platform (SP), for machine tools is a current trend. Some powerful analytical tools are needed to analyse the effect of errors in parallel structures. A model of a SP was analysed to include all the sources of errors [1]. We developed a similar error model to a Stewart platform and a Modified Stewart platform (MSP). Both SP and MSP designs have ...
