Features and Applications 

The H-820 hexapod achieves a velocity of up to 20 mm/s. It can be loaded with a maximum of 

20 kg in a vertical orientation and with a maximum of 10 kg in any other orientation. 
The parallel-kinematic design offers the following advantages: 

 

Positioning operations on six independent axes (three translational axes, three 

rotational axes) with short settling times 

 

High accuracy and step resolution on all axes 

 

No accumulation of errors of individual axes 

 

No friction and torques from moving cables 

The hexapod is controlled with a controller that can be ordered separately from PI (p. 8). The 

position commands to the controller are entered in Cartesian coordinates.
