Title:
FORCE DETECTION DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/043051
Kind Code:
A1
Abstract:
This force detection device (11) is provided with a support body (6), fluid bags (B1, B2), a fluid bag (BS), pressure sensors (S1, S2), and a calculation unit (C). The fluid bag (BS) is disposed on the opposite side from the side where the fluid bags (B1, B2) come into contact with the support body (6), and is disposed so as to be adjacent to both of the fluid bags (B1, B2). The calculation unit (C) acquires information about the internal pressures of the fluid bags (B1, B2) from the pressure sensors (S1, S2). When an object applies external force to the fluid bag (BS), the calculation unit (C) calculates the tangential force acting on the contact surface (CS) between the object and the fluid bag (BS) on the basis of the difference between the internal pressures of the fluid bags (B1, B2). The present invention makes it possible to obtain a force detection device capable of calculating the force acting on a contact surface (CS) in the tangential direction.
