Abstract:
A robot system includes a display portion which displays a robot model and a peripheral device model, a deployment portion which deploys a motion monitoring range model of the robot on the display portion, a positioning portion which moves and positions the motion monitoring range model, and a setting portion which converts a range surrounded by the positioned motion monitoring range model in the display portion into coordinate values which can be recognized by the robot to set the motion monitoring range.
Abstract:
An intelligent mobile robot having a robot base controller and an onboard navigation system that, in response to receiving a job assignment specifying a job location that is associated with one or more job operations, activates the onboard navigation system to automatically determine a path the mobile robot should use to drive to the job location, automatically determines that using an initially-selected path could cause the mobile robot to run into stationary or non-stationary obstacles, such as people or other mobile robots, in the physical environment, automatically determines a new path to avoid the stationary and non-stationary obstacles, and automatically drives the mobile robot to the job location using the new path, thereby avoiding contact or collisions with those obstacles. After the mobile robot arrives at the job location, it automatically performs said one or more job operations associated with that job location.
Abstract:
An entry detection device includes first light marks and second light marks. A control signal corresponding to a part of the first light marks is an error detection code of the control signal corresponding to the other part of the first light marks. A first inspection value is generated based on a first part of a light receiving signal corresponding to the other part of the first light marks. A second inspection value is generated based on a reverse bit string of a third part of the light receiving signal corresponding to a part of the second light mark paired with the other part of the first light marks. An entry is detected based on the first inspection value and the second inspection value.
Abstract:
Method to control the interference and/or collision between mechanical members of at least two operating or one operating unit with respect to fixed positions. At least one operating unit is associated with a position detector or with a position simulator, and is equipped with an electric which drives a mechanical member. The method is managed by a management and control unit. The control of the operating units occurs in two phases, verifying point-by-point the position of the mechanical member as a function of the current dynamics and the braking or acceleration times and spaces (first phase), and verifying the intensity of point-by-point current supplied to at least one electric motor (second phase).
Abstract:
In a device for protecting a work spindle (2) that is rotatably supported in a spindle head (4A, 4B) of a processing machine and/or a tool (3) clamped in the work spindle (2) from collisions with obstacles in the processing chamber (1) of the processing machine, a plurality of distance sensor modules (6) are arranged on or in a spindle nose (4B) that forms the termination of the spindle head (4A, 4B) toward the processing chamber (1) such that they point toward the processing chamber (1) and are connected to a common signal processing unit (8). When an obstacle is present in a predetermined area of the processing chamber (1), this signal processing unit generates a warning signal based on the measuring signals delivered by the individual distance sensor modules (6). An output (15) of the signal processing unit, at which the warning signal is generated, is connected to the machine control (16) of the processing machine. The distance sensor modules (6) preferably consist of radar or ultrasonic sensor modules.
Abstract:
A systems and methods for preventing tool damage in a computer controlled machining apparatus is provided. Conventional CNC machining apparatuses do not provide techniques for checking whether tool movement will interfere with one or more surfaces of the workpiece to be machined. The systems and methods carried out by the systems described herein address at least these deficiencies by providing a “crash test” or tool damage prevention routine that tests whether or not damage may occur based on a contact with the workpiece.
Abstract:
A numerical control device including a collision determining unit that detects a possibility of collision between a machine and an area set as an entry prohibited area; an operation-continuation instructing unit that instructs whether to continue an operation when the collision determining unit detects the possibility of collision and shaft movement is temporarily stopped; a machining-information storage unit that stores internal operation information of the numerical control device regarding the temporary stop when the operation-continuation instructing unit instructs continuation of the operation; and a collision-determination processing unit that invalidates a collision determination on the basis of the operation information stored in the machining-information storage unit when executing the same machining program the next and subsequent times.
Abstract:
An interference checking device 1 checks, during machining using an NC machine tool 20, interference between structures of the NC machine tool 20, a tool and a workpiece, and includes an interference check processing unit 2 virtually moving models and checking the occurrence of interference based on a position control signal from a numerical controller 30, and an operation effect degree evaluating unit 6 evaluating the degree of an effect of an operation on a possibility of the occurrence of interference. When a predetermined operation is performed during machining of a workpiece following a first workpiece, the interference check processing unit 2 moves the models at intervals determined based on the degree of the effect evaluated by the operation effect degree evaluating unit 6.

Abstract:
A measurement system that includes an industrial machine and an interferometer can detect when abnormality has occurred in measurement targeted at a reflector attached to a movable body, for example, in a case where the movable body has moved too close to the interferometer. A judging section of the interferometer judges that there is abnormality in measurement targeted at the reflector on the basis of a received-light signal. Upon such an abnormality judgment, a stop command outputting section of the interferometer outputs a stop command to the industrial machine. A stopping section of the industrial machine stops the driving operation of a moving mechanism upon receiving an input of the stop command, thereby stopping the movement of the movable body. The measurement system makes it possible to prevent the industrial machine, which includes the movable body and the moving mechanism, from colliding with the interferometer.
