Hexapods are parallel-kinematic motion platforms designed for high-precision positioning and alignment in six degrees of freedom: three translational (X, Y, Z) and three rotational (θX, θY, θZ). They consist of six length-adjustable actuators connected via joints between the base plate and a moving platform that carries the load.
This design enables high repeatability, stability and dynamic performance in a compact form factor, making hexapods ideal for complex alignment tasks. Thanks to various drive technologies, such as piezoelectric and electromagnetic, PI’s hexapods cover a wide range of application requirements. Advanced sensors and user-friendly controllers and software ensure easy operation and flexible motion control, including adjustable centres of rotation.
Hexapods are available in a range of sizes and configurations including compact, medium-sized, high-load and vacuum systems. Standard models support loads from 1 kg to 250 kg with repeatability down to ±0.06 µm, while customized solutions can handle payloads exceeding 2000 kg.
Compact Hexapods
PI’s high-precision miniature hexapods offer a perfect balance between size, payload, and performance. These ultra-compact hexapods are ideal for applications such as the positioning of tools or workpieces in micro-assembly, the alignment of optical fibers in silicon photonics, or the simulation of motions for functional tests. Vacuum versions down to 10-6 hPa are also available Read more
Medium Size Hexapods
PI’s medium-sized precision hexapods are available in a wide range of variants for the most diverse application requirements: from dynamic hexapods for motion simulation to systems with maximum repeatability for precise alignment to hexapods with folded drivetrains in a compact design that can position medium loads.

High-Load Hexapods
PI’s high-load hexapods position heavy loads safely and accurately, regardless of orientation or installation situation. This is made possible by special universal joints with Z-offset and other backlash-free, rigid components. Possible applications range from moving heavy components and optics to positioning inspection tools in industry and research to aligning reflectors in telescopes. Read more
Vacuum Hexapods
PI has many years of experience in vacuum technology and high vertical integration. Therefore, PI is ideally situated to offer standard and custom hexapods adapted to the requirements of vacuum applications: from the selection of the right design, suitable drive components, materials, and accessories, to the appropriate manufacturing processes and quality controls
Standard hexapods are available for vacuum surroundings of up to 10-6 hPa. Custom hexapods can even be designed for higher vacuum classes. Read more
