Abstract
Forces and moments are detected in a distinguishing manner by a simple structure. A supporting member () is positioned below a force receiving member (), which receives forces to be detected, and between these components, four columnar force transmitting members (to) are connected. Connecting members, having flexibility, are interposed at the upper and lower ends of each of the columnar force transmitting members (to) so that the columnar force transmitting members (to) can become inclined when the force receiving member () becomes displaced upon receiving a force. Sensors (to), each equipped with capacitance elements, are positioned at the connections parts of the respective columnar force transmitting members (to) and the supporting member () to detect forces that are transmitted from the respective columnar force transmitting members (to) to the supporting member (). Based on the detection values of the sensors (to), a detection circuit () detects, in a distinguishing manner, forces and moments acting on the force receiving member (). All of forces Fx, Fy, and Fz and moments Mx, My, and Mz can be detected.
