    • An articulated robot includes: different types of joint units, each joint unit including a stationary body, a stationary body-side mechanical connector provided in the stationary body for mechanical connection to another unit, a displaceable body coupled to the stationary body by a coupler, a displaceable body-side mechanical connector provided in the displaceable body for mechanical connection to another unit, and an actuator configured to displace the displaceable body relative to the stationary body; and a control unit including a controller configured to control the actuator and a control unit mechanical connector for mechanical connection to another unit, wherein displacement undergone by the displaceable body-side mechanical connector relative to the stationary body-side mechanical connector differs depending on the type of the joint unit, the stationary body-side mechanical connector includes a first connection structure, the displaceable body-side mechanical connector and the control unit mechanical connector each include a second connection structure, and the first connection structure and the second connection structure are connectable to each other.

    • A monitoring device of a robot system including: a robot including at least one joint axis and at least one servo motor which drives the joint axis, and a controller which controls the servo motor which drives the joint axis, the monitoring device comprising: a current sensor which detects a value of a current flowing through the servo motor; a current/torque converting section which converts the value of the current flowing through the servo motor which is detected by the current sensor into a torque value; a driving torque estimating section which estimates at least a part of driving torque required to drive the servo motor; a differential torque calculating section which calculates differential torque between the torque value obtained by conversion in the current/torque converting section and an estimated value of the driving torque; an external force converting section which converts the differential torque calculated by the differential torque calculating section into an external force applied to the robot; and a stop signal generating section which generates a stop signal for the robot based on a value of the external force obtained by conversion in the external force converting section, and supplies the stop signal to the controller.
