Hexapod 6-Axis Stages: High Performance 6-DOF Precision Positioning Systems & Motion Platforms

Hexapods, 6-axis positioning stages, are based on parallel kinematics, and often referred to as Stewart Platforms. A hexapod positioning system is based on a 6-axis actuator system (XYZ, Pitch, Roll, Yaw) arranged in parallel between a top and bottom platform. PI's parallel kinematics (PKM) multi-axis precision positioning systems have many advantages over conventional serial kinematics stages, including lower inertia, improved dynamics, smaller package size, and higher stiffness. The user-programmable pivot point – integral to all PI high-performance hexapod multi-axis motion controllers – provides additional benefits, especially in alignment applications of lenses, optics, and fiber optic components. Watch a short pivot-point demo video.

With three decades of Hexapod six-axis stage design and manufacturing experience, PI electro-mechanical hexapods and piezo hexapod positioners are the most advanced multi- axis precision positioning systems in the world, providing significantly higher precision than hydraulically driven systems. They are available in many sizes, and configurations for loads from 2 kg to more than 2000 kg, and most are self locking.

In addition to classical "Stewart Platform" type hexapods, PI also offers alternative parallel positioners, such as the SpaceFAB 6DOF Motion Platform design, which allows for longer linear travel ranges with a lower profile.

Controller and Software
PI hexapods are operated by dedicated, state-of-the-art vector motion controllers with virtual pivot point capability. An extensive software package including alignment algorithms e.g. for fiber optics etc, as well as simulation tools are included.

Vacuum and Atmospheric Version
Many of our hexapods and parallel positioners are available in vacuum versions, some for UHV levels to 10-9 Torr.

High-Speed / Dynamics Hexapod Platforms for Motion & Vibration Simulation
PI provides several solutions, with brushless motors and voice-coil linear motor direct drives. Watch video of highly dynamic, linear-motor hexapod platform.
