Parallel motion in all 6 axes with PI"s range of Hexapods

Hexapod systems have a decisive advantage over stacked single-axis systems: Since all drives act on the moving platform simultaneously (in parallel), the system has the same motion characteristics in all directions. This includes both the dynamic parameters and the accuracy.

Positioning tasks such as the alignment of samples or sensors that have no preferential direction of motion clearly benefit from the parallel-kinematic principle. For example, automated 6D alignment systems perform important tasks in the testing and manufacture of MEMS and photonics accessories. They include positioning and alignment of collimated fibers or assemblies.

A precise alignment in several axes can also be important for heavy objects, such as for telescope mirrors or for inspection systems for large-sized LCD monitors.
