Nanopositioning specialist
PI exhibits its
latest 6-axis robotics positioning system at the MD&M West
show, the world's largest medical design & manufacturing event.
The miniature hexapod system provides more than 10 lbs of force and
motion in all six degrees of freedom. It can be used for
manufacturing and placing of parts requiring very high precision,
for microscopy applications or laser and optical alignment.
After two decades of experience with the design and production
of hexapod robots, PI's electro-mechanical / piezoelectric six-axis
positioners are among the most advanced multiaxis precision motion
control systems in the world.
Features and Advantages of the M-810 Miniature
Hexapod
- Operation in Any Orientation
- High-Stiffness 6-Axis Hexapod with 5 kg Load Capacity
- Very Compact: 10 cm Diameter, 11.8 cm Height
- 0.2 Micron Minimum Incremental Motion (40 nm Resolution)
- Long Travel Ranges to 40 mm (linear) and 60°
(rotation)
- Powerful Controller with Freely Definable Virtual Pivot
Point
- High Velocity of 10 mm/s
- Linear and Rotary Multi-Axis Scans
Parallel Kinematics Advantages
Parallel-kinematic motion systems have a number of advantages over
standard serial kinematic (stacked) positioning systems:
- Virtual Pivot Point: Rotation Around any Point, not unlike the
Human Hand
- Only one Moving Platform, No Accumulation of Guiding and
Lever-Arm Errors
- No Moving Cables for Improved Reliability and Precision
- Smaller Package Size
- Increased Stiffness, Reduced Inertia, Better Dynamics
Smaller Motors and Encoders, Controller & Software
Included
The limited space necessitated the usage of new technologies for
encoders, motors and other integrated electronic components. The
M-810 is compatible with PI's tried and proven hexapod controllers
that are supported by windows software and a library of drivers and
programming examples for applications such as optical alignment
etc. PI also provides simulation tools for hexapod integration.
PI Hexapods come with load ranges from 2 kg to >1000 kg.
Applications
Precision manufacturing, high precision placement of parts;
alignment of optical components & lasers, microscopy
applications, neuroscience.
