Abstract: The safety of an operator which may be endangered by an erroneous instruction by the operator or a robot control system is ensured by making more stringent a condition regarding the separation of the operator from the vicinity of a robot when an operation program of the robot is activated. An interlock to which a condition regarding activation of the operation program of the robot is added is provided in a feeding unit which is connected to a robot controlling unit by wireless connection for charging a teaching unit, so as to provide a robot system which improves the safety of the operator.

Abstract: A robot system includes a robot and a robot controller including a drive unit, a memory that stores an arm-occupied region and a movement-forbidden region, a target position calculation unit that outputs a target position of a tool or a workpiece, a movement-forbidden region entry monitoring unit that checks whether the arm-occupied region based on the target position enters the movement-forbidden region and outputs a stop request if it is checked that the arm-occupied region enters the movement-forbidden region, and a predicted-coasting-position calculating unit that calculates a predicted coasting position of each axis and a coasting position of the tool or the workpiece in the case that the robot is urgently stopped. The movement-forbidden region entry monitoring unit checks whether the arm-occupied region at the coasting position enters the movement-forbidden region and outputs another stop request if it is checked that the arm-occupied region enters the movement-forbidden region.

Abstract: A wireless operating system is provided which can be applied even to such an environment that a plurality of controllers and a plurality of operating terminals are mixed with each other, and also, can readily establish communications within a short time. A first wireless station transmits a calling instruction to a second wireless station via a connection-purpose channel which has been set, and when the first wireless station receives a response, the first wireless station switches the connection-purpose channel to a communication-purpose channel contained in the response data.

Abstract: When a teach pendant is passed from one hand to the other hand in operating the teach pendant having two enable devices (three-position switches) at right and left sides, a problem arises that an operation is inhibited when the teach pendant is shifted from one hand to the other hand. Even when the three-position switches are operated by both the hands during shifting the teach pendant from one hand to the other hand, the operation can be performed Until a prescribed time passes. Thus, the teach pendant can be shifted from one hand to the other hand and can be continuously operated. When an operating time by both the hands exceeds the prescribed time, the operation is inhibited, so that a safety is ensured.

Abstract: There has been a problem that in the operation of a teach pendant having two enable devices (3-position switches) on the right and left sides, shifting it from one hand to the other results in prohibition of operation. In that operation is made possible until a predetermined time elapses even if the 3-position switches are operated by both hands in shifting the teach pendant from one hand to the other, shifting it from one hand to the other is allowed, making continuous operation of the teach pendant possible, while ensuring security in that when the time of operation with both hands exceeds the predetermined time, operation is inhibited.
