PI (Physik Instrumente) announced the H-820 hexapod. The lower-cost parallel positioning devices produce motion in all six degrees of freedom, such as XYZ as well as pitch, yaw and roll. The hexapod is ideal for industrial automation and manufacturing, neuroscience, bio-technology research, or for micro-manipulation, the alignment and assembly of mechanical components, micromachining, satellite testing, sensor alignment, X-ray microscopy and medical engineering.

The H-820 was developed for applications that require multi-axis motion and high flexibility but do not need precision on a nanometer or sub-micrometer level. The device is driven by powerful brushless motors. It features linear travel to 100mm, rotary travel to 60°, load capacity of 20kg, velocity of 20mm/sec, and resolution in the micrometer range.
The Hexapod is driven by six high-resolution actuators, all connected directly to one light-weight platform. This combines high system stiffness with a large clear aperture. Because of the low moving mass, small steps can be performed with significantly shorter settling times compared to stacked multi-axis positioners. Another advantage of this design is the randomized, user-programmable pivot point. In addition, there are no cable management issues and accumulation of runout and wobble errors such as with conventional stacked linear and rotary stages.
The H-820 hexapod includes an advanced motion controller and a comprehensive software package (alignment algorithms, simulation tools, programming examples, and LabView drivers).
