H-845 High-Load Hexapod

Positioning up to 1 Ton with Micrometer Precision

    • Load capacity to 1000 kg
    • Velocity to 50 mm/s
    • Repeatability to ±0.5 µm
    • Travel ranges to 340 mm / 60°
    • Scalable design: Dimensions, travel ranges and loads
    • Actuator resolution to 40 nm
    • Drive: brushless motors with brake
    • Sophisticated controller using vector algorithms, virtual pivot point
    • Extensive software support

Reference-class 6-axis positioning system

Parallel-kinematic design for six degrees of freedom making it significantly more compact and stiff than serial-kinematic systems, higher dynamic range, no moved cables: Higher reliability, reduced friction. Large clear aperture
Brushless DC motors with brakes

Rapid implementation of customer requests

The high-load Hexapod has a modular structure and uses a set of different modules for drive unit and joint. The platforms can be adapted to the customer's application. This allows for rapid implementation of special customer requirements

Powerful digital controller, open software architecture

6D vector motion controller for Hexapods, plus two additional servo axes. Arbitrary, stable pivot point, software-selectable. Positions commanded in Cartesian coordinates. Macro command language. Open-source LabVIEW driver and libraries. Determination of the workspace. Virtual machine for Hexapod emulation. Optional: Software for avoiding collisions in restricted workspace

Fields of application

Research and industry. For precision assembly, astronomy, aviation and aerospace

* The travel ranges of the individual coordinates (X, Y, Z, θX, θY, θZ) are interdependent. The data for each axis in this table shows its maximum travel, where all other axes are at their zero positions. If the other linear or rotational coordinates are not zero, the available travel may be less.
