The present invention relates to a collaborative
robot system used in an industrial environment where workers collaborate. The collaborative
robot system comprises: a collaborative
robot body having a multi-joint structure; a
control unit for controlling each joint or auxiliary shaft; one or more sensors for detecting the operational state of the robot in real time; and a status diagnosis and response module for diagnosing the state of the robot on the basis of detected data and controlling the operation of the robot accordingly. Specifically, the
system is configured to enable the robot to autonomously perform actions such as deceleration, stopping, and
recovery in response to various state changes occurring during work, and to perform self-learning and
trajectory optimization on the basis of data accumulated through repetitive tasks. Furthermore, the system includes a
graphical user interface (GUI) for intuitive user interaction, which is linked to a digital twin-based virtual
simulation environment, enabling presetting and modification of work paths. When multiple collaborative robots are operated together, the system enables task synchronization, path collision avoidance, and sharing of status information among the robots, and may be connected to an external control
server or a cloud-based
control system to allow integrated management of the entire
workflow.
