High-dynamics motion hexapod microrobot, voice coil drives, 1 kg load capacity, 250 mm/s max. velocity, flexures, high-performance power adapter, 3 m cable set
H-860 6-Axis Motion Hexapod
Magnetic Direct Drive for High Velocity
- High velocity and dynamics
- Minimal moved mass and inertia
- Velocity up to 250 mm/s
- Precise path tracking
- Friction-free voice coil drive
Thanks to its excellent dynamic properties, the H-860 is ideally suited for motion simulation.
It is used in test systems, e.g., for image stabilization in cameras and mobile devices. Further fields of application include quality assurance of camera test systems and image stabilization software; vibration simulation, eye tracking, simulation of human and artificial motion.
The friction-free drive design is based on voice coils drives and flexure guides. The struts and platform are made of carbon fiber for minimal moved mass and inertia.
Parallel-kinematic 6-axis system
Parallel-kinematic design for six degrees of freedom, making it significantly more compact and stiffer than serial-kinematic systems, no moved cables.
Precise running of predefined motion profiles with high path accuracy: Sine curves and freely definable trajectories.
PIMag® voice coil
Voice coil drives consist of two essential components: A permanent magnet and a coil that are located in the air gap of the magnetic field. Thanks to their low weight and friction-free drive principle, voice coil drives are particularly suitable for applications that require high dynamics and high velocities at limited travel ranges. High scan frequencies and precision positioning are also possible with these drives, because they are free of the effects of hysteresis.

The simulation software simulates the limits of the workspace and load capacity of a hexapod. Therefore, even before purchasing, you can check whether a particular hexapod model can handle the loads, forces, and torques occurring in an application. For this purpose, the simulation tool takes the position and motion of the hexapod as well as the pivot point and several reference coordinate systems into account.

When measuring position specifications, typical velocity is used. The data is included in the delivery of the product in the form of a measurement report and is stored at PI.
The maximum travel ranges of the individual coordinates (X, Y, Z, θX, θY, θZ) are interdependent. The data for each axis shows its maximum travel range when all other axes are in the zero position of the nominal travel range and the default coordinate system is in use, or rather when the pivot point is set to 0,0,0.
At PI, technical data is specified at 22 ±3 °C. Unless otherwise stated, the values are for unloaded conditions. Some properties are interdependent. The designation "typ." indicates a statistical average for a property; it does not indicate a guaranteed value for every product supplied. During the final inspection of a product, only selected properties are analyzed, not all. Please note that some product characteristics may deteriorate with increasing operating time.

Technology
Hexapod as Motion Simulator
Motion simulators have higher motion dynamics requirements (shakers).
Multi-Axis Positioners
Hexapod platforms are used for precision positioning and alignment of loads in all six degrees of freedom, three linear axes, and three rotational axes.
Magnetic Direct Drives
In particular in terms of wear and dynamics, magnetic direct drives offer advantages compared to common spindle-based technologies.
