A robot assembly for safe operation in a manufacturing setting with humans including a sensor for detecting a human location and human movement is provided. A safety control module providing a boundary of a safety zone area that is associated with the human in a task oriented state that includes a largest possible area in which the human or an associated work object can extend when the human is standing in one location and performing the work task. The human movement and safety zone area location being used to develop a capture set area that includes at least one predictive future safety zone area location. Using the at least one predicted future safety zone area, establishing a travel path for moving the robot between locations without overlapping the capture set area.

The present invention provides a mechanism for causing a safety controller to suitably display various pieces of information from a safety input device. A safety controller acquires a compatible port that connects at least one safety input device, and a safety input signal from the at least one safety input device connected via the compatible port and state information on the safety input device. Further, the safety controller 3 includes the MCU 23 that generates, in accordance with the safety program, a safety output signal based on the safety input signal acquired, and the display device 5a that displays, based on the state information acquired, a state of the safety input device from which the state information is acquired.

A soil compactor machine can include: a machine frame; at least one cylindrical roller drum rotatably coupled to the machine frame and rotatable about a drum axis oriented generally transverse to a direction of travel of the compactor machine; a plurality of sensors mounting locations on the machine frame for mounting one or more lidar sensors and cameras; and a plurality of brackets, wherein, one of each of the plurality of brackets is positioned at each of the sensor mounting locations for mounting the lidar sensors and the cameras, wherein the bracket at each of the sensor mounting locations has a similar design as the other of the plurality of brackets.

An optical safety sensor is inexpensively implemented. An optical safety sensor includes: a plurality of light projectors/receivers (a first light projector/receiver and a second light projector/receiver), which includes light projecting portions and light receiving portions; distance measurement portions, which measure distances using the time from light projecting to light receiving; and detection portions, which detect, based on measurement results, an abnormality occurring in any one of the plurality of light projectors/receivers; each of the light receiving portion provided in the plurality of light projectors/receivers receives reflected light caused by the light projected from the light projecting portions of all the plurality of light projectors/receivers.

Systems and methods for determining safe and unsafe zones in a workspace—where safe actions are calculated in real time based on all relevant objects (e.g., some observed by sensors and others computationally generated based on analysis of the sensed workspace) and on the current state of the machinery (e.g., a robot) in the workspace—may utilize a variety of workspace-monitoring approaches as well as dynamic modeling of the robot geometry. The future trajectory of the robot(s) and/or the human(s) may be forecast using, e.g., a model of human movement and other forms of control. Modeling and forecasting of the robot may, in some embodiments, make use of data provided by the robot controller that may or may not include safety guarantees.

Various embodiments of a jobsite keep out zone system are provided. The system includes one or more detectors configured to determine when an intruder is within and/or is approaching a protected area. In response to the determination, one or more alarms and/or notifications are generated.

A shaping or cutting machine, especially a skinner, at which an operator hand-feeds material to be cut or shaped toward a blade. Hand proximity detection devices are provided for operator safety; machine-vision across a surveilled volume before the blade, and conduction sensing devices. The blade is mounted on a rapidly retractable frame. Power from release of a spring physically moves the blade to a safe position if a hand is sensed. A gripping roller is driven by a rapidly stoppable motor.

A forming press having a machine bed on which a first tool is arranged, and having a tool carrier which is accommodated to the machine bed such that it can move relative thereto and further including a second tool and a drive for moving the tool carrier and a machine control for controlling the drive, and having a safety control for disabling the drive, wherein the safety control deactivates a first radiation detector if a first status signal, which results from a comparison between a first current position value with a first deactivation position value matches with a second status signal which results from a comparison between a second current position value with the first deactivation position value.

A digital slide scanning apparatus includes a safety light curtain that operates to disable the motor that rotates the carousel when the presence of an object (e.g., the fingers of an operator) is detected within a predetermined area of the carousel. The light curtain also operates to disable the motor that rotates the carousel when an improperly positioned glass slide or slide rack is detected. The digital slide scanning apparatus also includes a multi-color status indicator for each rack slot that indicates the rack slot location of an improperly positioned glass slide or slide rack.

The invention is directed to a safety device for a machine that includes a first transceiver unit for emitting a first light beam in a first time slot and for receiving a second light beam. The safety device includes a second transceiver unit arranged for emitting the second light beam in a second time slot that is different from the first one. The safety device also includes an evaluation unit for determining a reflecting object between the first transceiver unit and the second transceiver unit, only if the first light beam is received by the first transceiver unit in the first time slot or the second light beam is received by the second transceiver unit in the second time slot. Additionally, a non-reflecting object may be detected, if by neither of the two transceiver units in both time slots one of the two light beams is received.
