Overview of PI’s Q-821 Q-Motion® Miniature SpaceFAB Robot

This video features the Q-821 Q-Motion® Miniature SpaceFAB Robot from Physik Instrumente (PI). Equipped with Piezo-Motorized Inertia Drive, the Q-821 is a compact six-axis microrobotics system with a 1 nm sensor resolution. Piezo inertia drives are affordable and space-saving piezo-based drives with relatively high holding forces and an almost unlimited travel range. With crossed roller bearings, the point contact of the balls in ball bearings is replaced by a line contact of the hardened rollers. As a result, they are significantly stiffer and require less preload, which reduces friction and enables smoother running. They have a ±6 mm travel range in X and Y axes, and ±3 mm in Z axis, and also have rotary axes. The Q-821 has various industrial and research applications such as microscopy, measuring technology, micromanipulation, automation, and biotechnology.
