Abstract
A force detection device with a structure able to improve the accuracy for force-detection. A force detection device with a deforming member to be deformed under an external force, the force detection device comprising a fixation part which is a part fixed to an attachment to which the force detection device is to be attached. The fixation part is provided at the deforming member such that the fixation part protrudes from a bottom surface of a bottom part of the deforming member opposite to the attachment.
Claims6
A force detection device comprising:
- a deforming member to be deformed under an external force, the deforming member including:
- a bottom part;
- a top part arranged opposite to the bottom part so as to be separate from the bottom part;
- and
- a column extending between the bottom part and the top part;
- and
- a first fixation part which is provided so as to protrude from the bottom part and which is a part fixed to a first attachment to which the force detection device is to be attached,
- wherein the first fixation part includes a contact surface which contacts the first attachment,
- wherein the contact surface is separated from a base surface of the bottom part in a direction away from the top part, and is laterally separated from a side surface of the bottom part, and
- wherein the force detection device is attached, at the top part side, to a second attachment to which the force detection device is to be attached.
A robot comprising a force detection device, the force detection device comprising:
- a deforming member to be deformed under an external force, the deforming member including:
- a bottom part;
- a top part arranged opposite to the bottom part so as to be separate from the bottom part;
- and
- a column extending between the bottom part and the top part;
- and
- a first fixation part which is provided so as to protrude from the bottom part and which is a part fixed to a first attachment to which the force detection device is to be attached,
- wherein the first fixation part includes a contact surface which contacts the first attachment,
- wherein the contact surface is separated from a base surface of the bottom part in a direction away from the top part, and is laterally separated from a side surface of the bottom part
- wherein the force detection device is attached, at the top part side, to a second attachment to which the force detection device is to be attached, and
- wherein the robot is configured to detect an external force acting on the robot by the force detection device.
