Positioning hexapods are a specialized type of hexapods (or Stewart platforms) optimized for precise positioning and alignment tasks. Unlike general-purpose Stewart platforms, positioning hexapods prioritize accuracy, repeatability, and fine control of motion over dynamic specs like speed or acceleration . They are commonly used in high-tech industries where precision and flexibility are critical, such as optics, metrology, semiconductor manufacturing, astronomy, etc …

Main advantages & features:

1. High precision: Also called precision hexapods, positioning  hexapods offer exceptional accuracy in both translational (linear) and rotational movements, with displacement resolution and repeatability in the order of hundreds of nanometers and few micro-radians.
2. Wide payload capability: They can carry payloads from maximum 5 kg, up to 1.5 tonne, depending on the model, without compromising resolution and repeatability.
3. Compact design: they are very compact six-degrees-of-freedom robots, based on a parallel architecture, much more compact and efficient than serial mechanisms, therefore ideals for space-constraints environments such as clean rooms, TVAC chambers, etc …
4. Stiffness: Their parallel structure ensures high rigidity, stability and minimizes deflections under load.
5. Software control: Sym_Positioning GUI & API allows point-to-point and trajectory hexapod control to position and orientate it in any desired combination of translations and rotations within the hexapod working envelope.

Symetrie positioning hexapods are ranked by maximum payload capability, from maximum 5 kg for the SOLANO and the MAUKA, up to maximum 1.5 tonne for the JORAN. Some models such as the BORA, ZONDA and JORAN can be high-vacuum compatible.
