Hexapod Parallel Kinematic Positioning Platforms

 

PI is the global leader in Hexapod precision parallel positioning systems. PI's core business is ultra-precision motion control. With more than 750 employees world wide, 40 years of experience in motion control and more than two decades of hexapod mechanics, controller and software design experience, PI has the broadest and deepest portfolio of precision motion techologies and can match your application to the appropriate technology better than anybody else. PI recently acquired miCos, another motion control specialist with design experience in hexapods and other parallel kinematic positioning systems, to provide an even broader product offering. Our electro-mechanical and piezoelectric Hexapod Stewart-platforms have many advantages over hydraulic hexapods. They are smaller, provide much higher precision and most are self locking. Available in many sizes, configurations for loads from 2 kg to several tons. A recent investment in new building with test equipment and metrology for high load hexapod positioners will allow us to further strengthen our leading position.

Example: Parallel-Kinematics Micropositioning Systems
vs. Serial Kinematics (Stacked) Systems



Advantages of Parallel Kinematics (PKM)
Micro- and Nanopositioning Systems:
  • Lower Inertia
  • Better Dynamic Behavior
  • Smaller Package Size
  • Higher Stiffness
  • No Accumulation of Position Errors
  • Reduced Runout Errors
  • No Moving Cables: Better Repeatability
    and Reliability



Parallel Kinematics Hexapod Robot 6 Axis Micropositioning System.
  • Six struts support one common lightweight platform.
  • No accumulation of runout errors.
  • Virtual center of rotation, set by one software command.
  • No moving cables, no cable tension: better repeatability & higher reliability.

Serial-Kinematics "Stacked" 6-Axis Stage.

  • The bottom stage supports its own moving platform plus all stages above.
  • Runout errors and tilt errors accumulate.
  • Up to 5 moving cables cause friction and cable management problems.
