20110270443 | APPARATUS AND METHOD FOR DETECTING CONTACT POSITION OF ROBOT - An apparatus for detecting a contact position where a robot makes contact with an object includes a probe, a probe-position calculating unit, a contact detecting unit, and a contact-position calculating unit. The probe is attached to the robot and is configured to make a displacement in a direction of making contact with the object in an elastic manner. The probe-position calculating unit calculates a position of the probe of the robot in operation. The contact detecting unit detects a contact state of the probe with the object. When the contact state of the probe is detected, the contact-position calculating unit derives the contact position based on a calculated position of the probe. | 11-03-2011 |
20110270444 | SYSTEM AND METHOD FOR JUDGING SUCCESS OR FAILURE OF WORK OF ROBOT - A system for judging success or failure of a work of a robot includes a position command generating unit, a contact position detecting unit, and a work success/failure judging unit. The position command generating unit generates a position command enabling movement of a fingertip of the robot so that a position and posture detecting unit, which is attached to the fingertip of the robot and has an elastic transformation area, is brought into contact with a predetermined position relating to a work target after the predetermined work is performed for the work target by the robot. The contact position detecting unit calculates a contact position that is a position of a tip end of the position and posture detecting unit at the time of being in contact with the predetermined position based on a value of an external force applied to the fingertip and the position of the tip end of the position and posture detecting unit. The work success/failure judging unit judges the predetermined work to be successful when the calculated contact position is within a predetermined range and judges the predetermined work to be failed when the calculated contact position is not within the predetermined range. | 11-03-2011 |
20140145458 | POSITIONAL DISPLACEMENT DETECTOR, ROBOT HAND, AND ROBOT SYSTEM - The positional displacement detector includes a contact member, a prohibition member, and a vibration detector. The contact member is configured to make contact with the object and deform with a positional displacement of the object. The prohibition member is configured to make contact with the deformed contact member to prohibit a deformation of a magnitude equal to or more than a predetermined magnitude from being caused to the contact member. The vibration detector is configured to detect a vibration generated when the contact member has made contact with the prohibition member. | 05-29-2014 |
20140163735 | ROBOT SYSTEM, ROBOT, AND ROBOT CONTROL DEVICE - A robot system includes a robot and a robot control device. The robot includes a plurality of links connected to via a plurality of joint axes, servo motors that drive the joint axes, and a contact detection sensor that detects that one of the links touches an object. The robot control device includes a contact position determination unit that determines a contact position of the link based on an output of the contact detection sensor, a retracting direction vector calculation unit that calculates a retracting direction vector in a retracting direction of the link corresponding to the contact position, an assist torque calculation unit that calculates assist torque references for moving the links in the direction of the retracting direction vector, and a flexible control unit that adds the assist torque references to torque references for the servo motors to flexibly control the links. | 06-12-2014 |
20140163737 | ROBOT SYSTEM - A robot system includes: a robot including a camera unit shooting an object in a container, a hand gripping the object, and a contact detector detecting that the hand contacts the container; and a robot control device, which includes a control unit causing the hand to contact the container; a contact detection unit detecting by the contact detector that the hand contacts the container, and finding a contact position thereof; a first processing unit calculating a position of the container from a stereo image of the container acquired by the camera unit; a second processing unit calculating a difference between the position of the container calculated by the first processing unit and the contact position found by the contact detection unit as a correction amount; and a third processing unit correcting information on a position in a height direction of the object in the container based on the correction amount. | 06-12-2014 |
20140174239 | FORCE SENSOR AND ROBOT - A force sensor and a robot that can suppress a load applied to load sensor elements are provided. | 06-26-2014 |
