Hexapods / Parallel Kinematics

Hexapods, SpaceFABs and 6-Axis Positioning Stages

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.
