WHAT IS A HEXAPOD?
A hexapod is a mechatronic system with a parallel structure allowing the positioning and movement of objects in space according to the six degrees of freedom.
HEXAPOD ARCHITECTURE
A hexapod can be a positioning or a dynamic motion system.
Its architecture consists of six actuators mounted in parallel between a fixed and a mobile platform with the help of joints. The actuators perform linear movements to position the mobile platform.
PRECISION AND DYNAMICS
Symétrie hexapods are designed to be dynamic (simulators) or precise (measuring hexapod or micro-positioning hexapod). Their very low mass-to-stiffness ratio gives them great dynamics with a high load capacity.
WHY PARALLEL ARCHITECTURE?
■ Better footprint
■ Better mass/stiffness ratio
■ Improved mechanical robustness
■ No moving cables
■ Better accuracy
■ Less risk of default than a serial structure
■ Better inertia
Discover our wide range of precision positioning hexapods stages for loads from a few grams to several tons and resolutions from 10 nm to a few tenths of a micron.
We help you succeed in your dynamic motion projects, allowing you to test objects weighing from a few kg to several tons with up to 2m/s speed and 1g acceleration.
From the feasibility study to maintenance, Symetrie uses its skills in metrology, dynamics and positioning to offer you the best solutions, adapted to your constraints.
THE EXPERTISE OF Symétrie
Symétrie is the only French manufacturer of hexapod-type parallel structure mechanisms.
Our expertise is based on very advanced knowledge in high precision metrology and great experience in the implementation of this technology with high potential for innovation.
FOR WHAT APPLICATIONS?
Due to its original architecture, this system is used for high precision positioning, position measurement, and the generation of movements in the context of dynamic tests.
Hexapods find their applications in the naval, space, aeronautical, automobile, optical, medical, nuclear, or electronic industries. These systems are also used by research laboratories.
Some of our hexapods exist in an empty, cleanroom or non-magnetic version to adapt to particular environments.
