Micropositioner supports use in parallel kinematic systems

JULY 28, 2009--The Hexapod six-axis micropositioning system is driven by six LTA actuators that have been enhanced to match the requirements of parallel kinematic systems.

JULY 28, 2009--The Hexapod six-axis micropositioning system is driven by six LTA actuators that have been enhanced to match the requirements of parallel kinematic systems. The antifriction-coated spherical joint design provides more than five times higher rigidity and twice the load capacity of other similarly sized hexapods. The electronic controller is based on the XPS multiaxis controller, which masters the synchronized transformations from Cartesian input coordinates to the motion of the kinematic members. Controller features include instrument grade I/Os, hardware-based input triggers, event triggers, on-the-fly data acquisition, fast TCP/IP communication, and integrated TCL programming language for on-board processes.

PRESS RELEASE

Newport's 6-Axis Parallel Kinematic Micropositioning System

Irvine, CA - June 15, 2009 - Newport Corporation, a worldwide leader in laser and photonic solutions, introduces the high performance Hexapod, an easy-to-use and affordable 6-axis micropositioning system. The new system is driven by six industry-proven LTA actuators that have been enhanced to match the special requirements of parallel kinematic systems. The unique, anti-friction coated spherical joint design provides more than five-times higher rigidity and twice the load capacity of other hexapods of similar size.

The Hexapod electronic controller is a distinctive version of the Newport XPS advanced multi-axis controller which accurately masters the synchronized transformations from Cartesian input coordinates to the motion of the Hexapod kinematic members. Advanced features of the XPS controller, such as instrument grade I/O's, hardware-based input triggers, event triggers, high-speed on-the-fly data acquisition, fast TCP/IP communication, and integrated TCL programming language for on-board processes, make programming easier and improves throughput.

A standard feature of the powerful Hexapod XPS controller is a freely-definable, virtual pivot point which offers more flexibility in relocating both the pivot point and the entire coordinate system through advanced motion algorithms. Two user-definable coordinate systems are also provided: the TOOL coordinate system, which moves with the Hexapod, and the WORK coordinate system which is relative to the reference coordinate system. Incremental displacements are possible in either, since these are commonly-used Cartesian coordinates and positions can be easily calculated from one system to the other via a function call. These powerful functions provide a comprehensive and new way of mastering Hexapod motions without the need for complex, external coordinate transformations.
