ALIO’s patented next generation Hybrid Hexapod® takes a different approach to traditional 6 Degree of Freedom (6-DOF) positioning devices, and exhibits much higher performance at extremely competitive prices. Rather than 6 independent legs (and 12 connection joints) the Hybrid Hexapod® combines a precision XY monolithic stage, tripod, and continuous rotation theta-Z axis to provide superior overall performance. This renders traditional hexapod kinematics obsolete, with orders-of-magnitude improvements in precision, path performance, speed, stiffness and a larger work envelope with virtually unlimited XY travel, and fully programmable tool center point locations.

The Hybrid Hexapod® has less than 100 nm 3-Dimensional 6 axis Point Precision® repeatability, making it an essential technology for mission critical applications in the laser processing, optical inspection, photonics, semiconductor, metrology, and medical device sectors, and indeed all micro-machining projects.
Traditional hexapods cannot achieve sub-micron accuracy because they require the accurate coordination of the movement of all six axes to accomplish a motion profile, even if the requirement is only for a simple single-axis motion. In addition, despite the fact that the general perception is that hexapods exhibit good stiffness compared to serial stacked multi-axis systems, this is really only in the vertical “z” axis, with weaknesses in the “xy” plane.
MINI Hybrid Hexapod
ALIO’s MINI Hybrid Hexapod® is ideal for automated lens alignment/bonding to CCD arrays. It has been helpful in building camera array modules, translational OIS, telescopic integrated lenses for miniature cameras used in every day products like cell phone cameras and drones. Any application requiring 6- degrees of freedom positioning with nanometer/arc-sec levels of incremental motion and repeatability is a good fit for this product where product sensor resolution improvements are driving the need for higher precision.
