Abstract: A controller includes: a deformation information obtaining unit configured to obtain information on deformation of a suction portion that suctions an object with negative pressure, and that is deformed by the negative pressure; and an operation control unit configured to control movement of the suction portion in accordance with deformation of the suction portion.

Abstract: A suction pad suctions an object under a negative pressure, and includes a stationary section fixable on a support, and a deformable section deformable under the negative pressure. The deformable section includes a plurality of marks at a plurality of positions spaced from one another and displaceable with respect to the stationary section in response to deformation of the deformable section. The plurality of marks are optically identifiable. The plurality of marks are continuous across the plurality of positions or are separate at the plurality of positions.

Abstract: The purpose of the present invention is to provide a device for outputting holding detection results by a highly accurate simulation in consideration of parameters related to a holding member. A user enters workpiece information through an input UI unit. A selection control unit executes an automatic selection process of a suction pad based on the workpiece information input through the input UI unit, an automatic selection process of a workpiece physical model, an automatic selection process of a robot, and a confirmation process of a vibration tolerance, and then displays the selection results. The selection control unit determines whether there is a problem with the selection results based on an input instruction from the user.

Abstract: A robot hand, and a robot hand control method and program are provided that are capable of performing an assembly task at high speed while alleviating shock between a gripped object (20) and an assembly target object (22). A robot hand (100) includes a hand (12), a displacement sensor (14), an estimation section, and a controller (16). The hand (12) includes an anti-slip mechanism at a contact portion with the gripped object (20) and a mechanism capable of anisotropic movement in three degrees of freedom under external force. The displacement sensor (14) is configured to detect a displacement amount of the hand (12) when an external force has been applied to the hand (12) from a state of mechanical equilibrium existing prior to application of the external force.

Abstract: A motion instruction value calculation unit is configured to calculate operation instruction values of a pick-and-place apparatus to be simulated. A dynamics calculation unit is configured to read the operation instruction values that are output from the motion instruction value calculation unit, and to calculate an apparatus operation considering the dynamics. Based on the apparatus operation considering the dynamics, the suction success/failure calculation unit is configured to determine whether a workpiece is successfully sucked by a suction pad. A 3D display unit is configured to display a 3D image of the apparatus operation considering the dynamics in a display unit such as a liquid crystal display.

Abstract: A simulation apparatus includes a load deriving unit that derives a load moment that is generated in an elastic suction pad that holds a workpiece due to the difference between the acceleration rate of a robot arm to which the suction pad is attached and the acceleration rate of the workpiece when executing a simulation in which a simulation model including the workpiece, the suction pad, and the robot arm is moved at an accelerated rate based on an operation instruction, and an execution condition change unit that performs processing for changing, if the load moment derived by the load deriving unit is larger than a threshold value, an execution condition of the simulation such that the load moment derived by the load deriving unit does not exceed the threshold value.
