Research on high-precision dynamic and static calibration technology for tactile sensors
Aims:A high-precision dynamic and static calibration method and device for tactile sensors was proposed.Methods:The device used the STM32 microcontroller as the core processor,which received instructions from the upper computer and controlled the motion of the linear motor.The force sensing module collected real-time force values during the calibration process and fed them back to the microcontroller.By processing and calculating the error,the position of the linear motor was corrected until the calibration was completed.Finally,the uncertainty was calculated and analyzed.Results:The experimental results indicated that the device could calibrate the compressive force of tactile sensing in the range of 1.000 5.000 N under dynamic conditions.Conclusions:The device has high calibration precision and accuracy in calibrating the tactile sensor's pressure direction force,taking into account the dynamic force calibration;and has high practical application value.
