Title:
DETECTION DEVICE AND SENSOR CALIBRATION METHOD
Document Type and Number:
WIPO Patent Application WO/2020/170770
Kind Code:
A1
Abstract:
A detection device 12 according to the present invention comprises a calibration means 14 for specifying a relational expression between the value output from a force sensor 11 when external force is applied and the magnitude of the external force. The relational expression comprises a formula that includes a prescribed parameter and with which it is possible to calculate the magnitude of the external force from the actual output value according to an offset value that is an output value from a non-contact time when external force was not being applied. The calibration means 14 comprises a function derivation unit 17 for deriving a function for determining a parameter value from the offset value and a parameter value determination unit 18 for using the function to determine the parameter value. The function derivation unit 17 generates the function from an output value when a known external force was applied and a preceding offset value. The parameter value determination unit 18 determines the parameter value from an offset value acquired in a state in which the force sensor 11 was disposed on a prescribed site for external force measurement.
