| Abstract: | In order to solve the deficiency that the existing tactile force calibration system can hardly realize the calibration of any haptic unit in flexible tactile sensor array, and to overcome the drawbacks of low precision, difficult to operate in existing tactile force calibration system, a tactile force calibration and loading system for flexible tactile array sensor is designed and developed in this paper. A STM32F103VET6 high performance microprocessor is adopted to control the stepper motor and S shape high precision force sensor, and achieve 2D force precise loading and calibration, and the calibration information is displayed on the host PC as real time graphical display. The structure characteristics, operating principle and system software and hardware design of the calibration platform are introduced. Through system error analysis and platform calibration test, the proposed system can achieve the two dimensional force loading range of 0~50 N and the normal and tangential accuracy of 0.18%FS. The tactile force loading application experiments show that the loading platform has high measurement precision and strong practicability, which provides a good solution for the two dimensional force loading and calibration of flexible tactile sensor array with different units. |
