A Tougher Hexapod Micro-Positioning System for 24/7 Industrial Operation

Auburn, MA - The H-815 6-Axis Hexapod is a ruggedized, highly accurate, positioning and alignment system designed for continuous 24/7 operation in demanding industrial motion applications. Engineered as a durable parallel kinematic machine for high-precision alignment tasks, it provides six degrees of freedom (6-DOF) - X, Y, Z, pitch, roll, and yaw - delivering exceptional flexibility for applications requiring multi-axis motion with high accuracy.

With a low-profile design (only 155 mm height), a small footprint for a 6-axis system (222 mm baseplate diameter), and a 22lbs load capacity, the sturdy H-815 hexapod seamlessly integrates into production lines while maintaining robust performance, even when mounted in various orientations. Unveiled at SPIE Photonics West 2025, the world's leading conference on photonics, it is ideal for camera lens alignment (automotive, cell phones etc.), micro-assembly, aerospace test and assembly, Micro-LED production, fiber optic alignment, aerospace test and assembly, and other precision-critical applications.

Experience in High-Precision Engineering is the Basis for Superior Performance
Backed by 35 years of hexapod engineering expertise and five decades of nano-positioning and micro-positioning innovation, PI has equipped the H-815 with industry-leading joints, actuators, and encoders for unmatched motion control performance, reliability, and stability.
• Advanced joints for maximum stability: Custom-designed cardanic joints with Z-offset provide superior stiffness over traditional universal joints and spherical joints, ensuring precise, backlash-free motion in any orientation.
• High-performance actuators: Ball screw actuators minimize friction and enhance durability, outperforming conventional lead-screw designs found in lower-cost hexapods.
• Absolute encoders: All six actuators feature absolute-measuring encoders, eliminating the need for referencing, reducing startup time, and enhancing overall precision.
