Precision hexapod microrobot, brushless DC gear motor, absolute encoder, 50 kg load capacity, 8 mm/s velocity. Connecting cables are not included in the scope of delivery and must be ordered separately.
H-850 6-Axis Hexapod
For Loads to 250 kg
- Load capacity to 250 kg
- Repeatability to ±0.2 µm
- Travel ranges to ±50 mm / ±30°
- Works in any orientation
The H-850 series hexapods position loads of up to 250 kg with high precision and reliability. Heavy-duty precision bearings allow applications with long duty cycles.
The parallel-kinematic design for six degrees of freedom makes it significantly more compact and stiffer than comparable serial kinematic systems. The advantages over serial, i.e., stacked systems, are mainly the much better path accuracy and repeatability. In addition, the moved mass is lower and allows improved dynamics which is the same for all motion axes. Cable management is not a problem because cables are not moved.
Use of brushless DC motors (BLDC)
Brushless DC motors are particularly suitable for high rotational speeds. They can be controlled very accurately and ensure high precision. Because they dispense with sliding contacts, they run smoothly, are wear-free and therefore achieve a long lifetime.
Absolute Encoder
Absolute encoders supply explicit position information that enables immediate determination of the position. Therefore, no referencing is necessary when switching on and this increases efficiency and safety during operation.
PIVirtualMove
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.
