Why Google Engineers can make better Cameras using PI’s Direct-Drive Hexapod Multi-Axis Motion Platform

Google’s Pixel 2 has one of the most advanced cameras found in smartphones today. In a recent YouTube video by “Nat & Friends” on how Google built the Pixel 2 Camera, PI’s H-860 “shaker” hexapod is shown in a motion simulation application. Modern cameras use electronic image stabilization algorithms to reduce side effects from motion […]

Hexapod 6-Axis Micro-Robots – Enablers for Today’s Advanced Camera Manufacturing… and Tomorrow’s

Hexapod micro-motion robots are a novel motion technology that provides all six degrees of freedom in an unusually stiff, compact, and high-precision structure, composed of a single moving platform supported in parallel by six motorized struts arranged with optimized constraint (“parallel kinematics”). From a motion control standpoint, hexapods are the equivalent of an XYZ stack with […]

Stacks of Single Axis Stages vs. Hexapods

When faced with a multi-axis motion application, many users stack motion stages, and in fact that is a fine approach for assemblies of just a few axes. But as applications become more complex, so do the equivalent stacks-of-stages, and very real and practical considerations begin to come into play. Stiffness.  Some stage manufacturers publish stiffness […]
