Positioning device and positioning method of processing tool
A device for positioning a processing tool: a processing tool for processing the to-be-processed workpiece's surface while pressing the surface to be processed; a movement mechanism able to displace processing tool's distal end in a first direction orthogonal to the surface to be processed and/or a second direction parallel with the surface to be processed; a force sensor able to detect a force in the first and second direction applied to the processing tool's distal end pressed onto the surface to be processed; and a control device for executing a correction step for controlling the movement mechanism so the surface to be processed is pressed while the distal end's position of the processing tool is aligned with a processing reference position on the surface to be processed, and correcting the processing tool's position so that the force in the second direction is within a specific value or less.
Attachment apparatus, attachment method, and hand mechanism
An attachment apparatus according to an embodiment of the present technology includes a hand portion and a control unit. The hand portion includes a restriction portion that restricts a movement of a flat cable in a width direction and a holding portion that holds at least one of both surfaces of the flat cable. The control unit causes the flat cable to be held by a first holding force while restricting the movement in the width direction at a first position on the flat cable, causes the hand portion to move to a second position on the flat cable while maintaining the first holding force, and causes the flat cable to be held at the second position by a second holding force to attach the flat cable.
