The basis of this research is to design and fabricate a new type of alternating arrangement of three-axis piezoelectric sensors dynamometer for measuring six-component force/torque measurement. The system consists of a long dynamometer with eight tri-axial piezoelectric sensors alternatively distributed. The design theory of the piezoelectric six-axis force dynamometer is established, including a finite element model (FEM: ANSYS analysis) and experimental model (static and dynamic calibrations). Structural design is constructed for analyzing the operating principle and performing the experimental measurements. The multipoints measurement (MP-M) model is fabricated based on the established alternate arrangement pattern and force application of multi-points allocation to apply the force/torque. Therefore, this work describes linearity error, repeatability error and cross-talk error of the constructed model. However, the designed model is not limited only to an alternate arrangement pattern of tri-axial sensors. But in the future, other types of arrangements will be researched and will be experimentally performed.
