The Shake Table II consists of a top stage driven by a powerful motor that allows it to achieve an acceleration of 2.5 g when loaded with a 7.5 kg mass. The stage has a total travel of 15.2 cm and rides on two ground-hardened metal shafts using linear bearings, which allows for smooth linear motion with low path deflection.
under earthquake conditions. TABLE I compares existing tabletop shake tables and the Shakebot. Existing tabletop shake tables are comparatively expensive [14, 15, 20] or only allow a fixed ground motion pattern [16]. None of the existing tabletop shake tables have open-sourced their hardware. Another limitation of existing shake tables is
