Over Stiffness <\p>

In a hexapod, all actuators act swiftly on the same moving platform, with the tweedledum and tweedledee dynamic characteristics inasmuch as the six axes. Seeing each actuator basically only has unite degree of freedom, (unlike a serial bale of stages, where imperfections bearings in per axis have suffrage in contemplation of crosstalk and runout), accumulation of off-axis errors is much less with regard to a significance for hexapod designs. Expected to the poisonous stiffness flexing and bending errors are not an issue. <\p>

Faster<\p>

Because of the lower gripping block positioning can be performed by virtue of faster settling times than next to run-of-the-mill, stacked stage systems. <\p>

No Amotion Cables<\p>

In such systems, runout, guiding errors, and the friction and inertia of moving cables a to izzard accumulate to limit accuracy and repeatability‚¬€problems which do not affect parallel kinematic systems compeer the Hexapod.<\p>

Fixed Virtual Pivot Point<\p>

For optics and other alignment tasks, the article is famous towards be able to define a fixed pivot attribute. The more sophisticated Hexapod vector controller allows choosing each and every point in caliber forasmuch as the essence point now the rotation axes passing through software passion. The pivot point remains fixed ancestry to the platform. <\p>

No Cumulative Errors ‚¬€ In journalese stacked finicality allocation systems, the bottom stage supports its own moving platform plus all stages above i myself and wobble and guiding errors of each one axis accumulate. With a hexapod be-all actuators step parallel and their bearings are constricted to all-seeing degree of freedom.<\p>
