A planning system includes search circuitry configured to run a simulation to repeatedly generate candidate positions which are candidates for a target position with respect to a motion of a robot, and selection circuitry configured to select the target position among the candidate positions. The search circuitry includes evaluation circuitry configured to calculate an evaluation value corresponding to each of the candidate positions, estimation circuitry configured to generate a calculation model showing a relationship between each of the candidate positions and the evaluation value with a regression analysis, and setting circuitry configured to set a new candidate position based on the calculation model.

Planning system, planning method, and non-transitory computer readable storage medium

A robot includes a robot body, a control processor, a detection circuit, a memory, and a determining circuit. The control processor is configured to control the robot body to perform a work on a workpiece while the workpiece is conveyed. The detection circuit is configured to detect external force which the robot body receives from the workpiece. The memory is to store a threshold force. The determining circuit is configured to determine whether the external force is equal to or larger than the threshold force.

Robot, control method of robot, and machining method of workpiece

A robot system includes at least one robot, a first sensor, at least one second sensor, and circuitry. The at least one robot is to work on a workpiece. The first sensor is to detect a three-dimensional shape of the workpiece. The at least one second sensor is to detect a three-dimensional position of the workpiece. The circuitry is configured to control the at least one robot based on teaching data. The circuitry is configured to correct the teaching data according to the three-dimensional shape detected by the first sensor. The circuitry is configured to correct the teaching data according to the three-dimensional position detected by the at least one second sensor.

Robot system, method for controlling robot, and robot controller

A robot according to an embodiment includes a base, a first structure, a second structure, and a third structure. The first structure is connected to the base to be rotatable about a first axis. The second structure is connected to the first structure to be rotatable about a second axis orthogonal to the first axis. The third structure is connected to the second structure to be rotatable about a third axis parallel to the second axis. The first structure and the third structure are formed by using cast materials having a same shape.

Robot

A vertical articulated robot includes a base, a turning base, a first upper arm, a second upper arm, a front arm, a wrist assembly, a first motor, a second motor, a third motor, a fourth motor, and a wire body. The wire body includes a first wire portion, a second wire portion, a third wire portion, a fourth wire portion, a fifth wire portion, and a sixth wire portion. The first wire portion extends from the turning base along a third rotation axis and is connected to an outer surface of the first upper arm. The second wire portion extends from the first wire portion along a plane perpendicular to the third rotation axis and is connected to an outer surface of the first upper arm. The third wire portion extends in a U-shape from the second wire portion.

Vertical articulated robot

A vertical articulated robot includes a base; a turning base provided on the base so as to be pivotable about a first rotation axis; a first upper arm provided on the turning base so as to be turnable about a second rotation axis that is in a plane perpendicular to the first rotation axis; a second upper arm provided on a distal end portion of the first upper arm so as to be pivotable about a third rotation axis that is perpendicular to the second rotation axis; a front arm provided on a distal end portion of the second upper arm so as to be turnable about a fourth rotation axis that is in a plane perpendicular to the third rotation axis; and a wrist assembly mounted on a distal end portion of the front arm. A motor that rotates the second upper arm is mounted on a frame of the second upper arm.

There is provided an industrial robot having no interference of a cable for an end effector or the like with a peripheral apparatus. An end effectoris fixed to a wrist flangethrough an intermediate member. The intermediate membertakes the shape of a crankshaft in which a first flangeattached directly to the wrist flange, a second flangeprovided at a predetermined interval in parallel with the first flangeand attached directly to the end effector, and two membersandfor coupling the first and second flangesandare arranged symmetrically.
