use of human motion sensors to detect movement when in close proximity to hydraulic robots

摘要

The present invention relates to an advantageous embodiment which includes a machine system operating in a manufacturing environment. The system includes a sensor system and a computer. The sensor system is configured to distinguish human skeleton positions from non-human object positions and to determine if one or more humans are present in a predetermined area. The computer is configured to: In response to the determination that only one or more humans are in the predetermined area, determine if a false positive result has occurred, where the false positive comprises a first determination that one or more humans are present when There is no human being really present. The computer is also configured to: In response to the determination that the false positive result did not occur, consider an action selected from the group consisting of issuing an alert, stopping the machine, or a combination thereof.
