Static and Dynamic Calibration for FlexiForce Sensor Using a Special Purpose Apparatus

This paper introduces an experimental apparatus to be implemented for calibrating the FlexiForce sensor both statically and dynamically. This sensor uses a resistive – based technology and it has force range of (0-111N). The static calibration is done with static weights under static conditions, also these sensors are calibrated dynamically with the use of an inertial force of a mass as the known dynamic force; the acceleration of the mass is measured by an accelerometer board attached to the oscillating mass. These sensors are calibrated with the same conditions under which force sensors are supposed to be used, as to measure the force on the fingertip of a robotic manipulator. Results of both calibration methods are presented and discussed herewith
