A sensor system according to the present disclosure includes a substrate with a reference plane, a plurality of kinesthetic-sense sensors disposed on the substrate, each of the plurality of kinesthetic-sense sensors being configured to output signals of three axial directions corresponding to an orthogonal-axis direction orthogonal to the reference plane and two axial directions parallel to the reference plane, respectively, according to an external force from an object received at a force receiving part, a control unit configured to determine whether or not a value of each of the signals is larger than a predetermined threshold, and calculate a pressing force in the orthogonal-axis direction or a moment around the orthogonal axis received from the object based on a result of the determination, and an output unit configured to output a result of the calculation.
