M-850 Hexapod 6-Axis Positioning System

High-Load Parallel-Kinematics Micropositioner with Controller, to 2000 N

The M-850 is the ideal micro-

positioning system for all

complex positioning tasks

which depend upon high load

capacity and accuracy in six

independent axes. The use of

extremely stiff and accurate

components for the M-850

Hexapod results in an unusu-

ally high natural frequency

of 500 Hz with a 10 kg load. In

addition to positioning all axes

with resolutions in the submi-

cron and arcsecond ranges,

it allows the user to define

the center of rotation (pivot

point) anywhere inside or

outside the system envelope

by one simple software com-

mand.

The M-850.50 model can

achieve velocities of up to

8 mm/s. In contrast, the

M-850.11 model with a higher

gear ratio can achieve a load ca-

pacity of 250 kg vertically and

50 kg in any orientation.

Hexapod vs. Serial Kinematics

Systems

The Hexapod is driven by six

high-resolution actuators all

connected directly to the same

moving platform. This design

provides a high system stiff-

ness and a large clear aperture.

Because of the low mass of the

moving platform, positioning

operations can be performed

with far lower settling times

than with conventional,

stacked multi-axis systems. In

such systems, runout, guiding

errors, and the friction and iner-

tia of moving cables all accu-

mulate to limit accuracy and

repeatability—problems which

do not affect parallel kinematic

systems like the Hexapod.

Fixed Virtual Pivot Point

For optics and other alignment

tasks, it is important to be able

to define a fixed pivot point.

The sophisticated Hexapod

controller allows choosing any

point in space as the pivot point

for the rotation axes by soft-

ware command. The pivot point

remains fixed relative to the

platform.

Target positions in 6-space are

entered in user-friendly coordi-

nates and reached by smooth

vectorized motion.

Open Architecture

Control of the hexapod is facili-

tated by the controller´s open

interface architecture, which

provides a variety of high-level

commands and includes a

macro language for program-

ming and storing command se-

quences.

Automatic Optical Alignment

With the internal or external

photometer option and the in-

tegrated scanning routines, just

a few commands are needed to

perform an automated align-

ment of optical components.

tometers / optical power me-

A smaller, even-more-precise

hexapod, specially developed

for alignment of collimators,

fiber bundles and I/O chips,

is available as the F-206

(see p. 4-12).
