In recent years, earthquakes have caused the collapse of numerous constructions and buildings, and killed thousands of people. A small scale seimic emulator is designed to regenerate seismic waves, which can be used to evaluate the performance of a scaled buidling or construction in civil engineering. The emulator is a robot device that consists of a plate movable in a planar plane, two DC servo motors with built in quadrature encoders for acutation and sensing, and a NI CompactRIO for control signal. A control strategy based on inverse dynamics and feedback is used to track the recorded seismic waves.
