Abstract

The measurement of torque and angle is widely used in industrial mechanical arms and wheeled robots. The split torque sensor and rotary encoder have the disadvantages of high installation difficulty, complex wiring, large joint volume and high cost. A new type torque/angle multi-function sensor was presented in this paper. The mechanical structure of the torque sensor cross waist hole elastomer and hollow shaft angle sensor was designed. The structural parameters of the sensor were optimized by the workbench finite element technology. The hardware circuit and software algorithm of the composite sensor were carried out. The experimental calibration system of the composite sensor was built. The experiment demonstrates that the sensitivity of torque measurement is 0.102 (V/(N·m)), the linearity is 2.12% FS, the repeatability error is 0.61% FS and the hysteresis is 0.94% FS. The angle measurement error is ± 0.05°. The measurement accuracy meets the needs of industrial applications and has the advantages of small size, convenient use and high cost performance.
