Nanopositioning specialist PI has introduced the world’s smallest commercially available electro-mechanical, high-force Hexapod 6-axis micropositioning system.
After two decades of Hexapod design and manufacturing experience, PI electro-mechanical Hexapods and piezo Hexapods are among the most advanced multiaxis precision positioning systems in the world. The new M-810 ultra-compact miniature Hexapod is no exception.
Features and Advantages of the M-810 Miniature Hexapod
- High-Force 6-Axis Hexapod with 5 kg Load Capacity
- Very Compact: 10 cm Diameter, 11.8 cm Height
- Sub-Micron 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
- Operation in Any Orientation
- 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:
- 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
- Virtual Pivot Point
.
Smaller Motors and Encoders, Compatible with Existing Controllers
The limited space necessitated the usage of new technologies for encoders, motors and other integrated electronic components. Nevertheless, 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 offers Hexapods with load ranges from 2 kg to >1000 kg.
