PROBLEM TO BE SOLVED: To provide a robot system capable of shortening tact time of a series of works including holding and transporting a work-piece.SOLUTION: A robot system 100 includes: a robot arm 14 for transporting a work-piece 200 held by a robot hand 12; a robot arm 24 to which a laser light radiation part 25 and a camera 26 are attached that detect the arrangement state of the work-piece 200 arranged in a pallet 201 in order to operate the robot arm 14 on the basis of the arrangement state of the work-piece 200 arranged in the pallet 201; and a robot controller 4 and a PLC 5 which perform controlling during the operation of the robot arm 14 so that the laser light radiation part 25 and the camera 26 of the robot arm 24 detect the arrangement state of the work-piece 200 arranged in the pallet 201.

PROBLEM TO BE SOLVED: To solve a problem that the teaching of a position and posture must be strictly performed and teaching work requires considerable effort.SOLUTION: A sensing instruction is inputted at a sensing point which is a rough taught point in a teaching mode (S22). The instruction and sensing point are stored (S23). Furthermore, a target angle and advance/retraction angles are inputted (S24). A robot is moved to the sensing point in a sensing mode (S32) to actuate the detection of a laser sensor, thereby acquiring the shape of a workpiece (S33), and to create a work program by calculating the position and posture (S35). Therefore, it is possible to greatly simplify the teaching work in an environment where the displacement of the workpiece does not occur.
摘要:
A method for recognizing, collecting and repositioning objects (1) having non-predetermined dimensional characteristics and which are arranged on a support surface (2) is implemented by means of a gripper group (30). The gripper group (30) is mobile in at least a lengthwise direction of movement relative to an object (1) to be handled, a direction of moving towards/away from the object (1), and a direction of adjustment of the height relative to the object (1). The gripper group (30) is controlled by a computerized control unit. The method comprises the following operating stages: a stage of approaching and recognizing an object (1), comprising the approximately-set approach of the gripper group (30) to the object (1), performed with the assistance of positional information stored in the control unit; identification of the outline of the object (1), by perpendicular three-dimensional scanning performed, using sequences of movements of the gripper group (30), by means for gauging punctual distance (50) arranged near at least one finger (35, 36) of the gripper group (30), and by sensor means (55) for detecting the presence of the object (1), which identify the depth of the object and are arranged at the head of the fingers (35, 36); a stage of gripping the object (1); a stage of collection the object (1), comprising operations of lifting and moving the object (1).
