Abstract: In one aspect, a processing method is executed by a processor to perform processing related to driving of a host moving object that is configured to communicate with a target moving object. The processing method includes: monitoring an envelope violation that is a violation of a safety envelope in which safety of intended functionality is set in the host moving object with respect to another road user other than the target moving object; and generating, when the envelope violation is recognized in the host moving object, warning information for warning of the envelope violation that is to be transmitted to the target moving object.

Abstract: An articulated robot has a fixing stand for supporting the robot body and a swivel stand which is rotatably disposed on the fixing stand. An upper arm which is rotatably connected at one end to the swivel stand has a forearm rotatably connected to its other end. The forearm has an operating part at one end and includes a plurality of wrists which are sequentially connected between the operating part and the upper arm. The wrists are directly driven by a plurality of drive motors mounted within the plurality of wrists and along the central axis of the forearm.

Abstract: A swivel shaft backlash correcting device for an arc welding robot in which backlash is eliminated, even if the gear teeth of the assembly are significantly worn. A spur gear is mounted at one end of a gear shaft, and an uprightly extending first pin is fixed to a flat part of the spur gear, the shaft being coupled through a speed reducer to an electric motor. A second pin is fixed to a flat part of a correcting gear having the same diameter and number of teeth as the spur gear and being mounted on the same shaft as the spur gear above the spur gear. A retaining ring is engaged with the first and second pins in one of a contracted or compressed state thereof so as to apply a force of expansion between the gear shaft and correcting gear. A center gear is secured to a stationary stand and engaged with the correcting gear and spur gear.

Abstract: An articulation mechanism of an arc welding robot is provided with a driving arm and a driven arm, a motor being contained in the driving arm. A forked articulation housing extends from the tip end of the driven arm with a transmission gear mechanism being provided at one inner side thereof, and a position-shift preventing mechanism being provided in its other inner side. The transmission gear mechanism transmits a driving force from an output shaft of the motor to an input shaft of the driven arm. The position-shift preventing mechanism prevents the position-shift of the input and output shafts.

Abstract: A robot includes a generally cylindrical stationary table adapted to be fixed on a floor, and has an outer peripheral surface formed with a circumferential gear. A rotary table is supported rotatably about the outer peripheral surface of the stationary table. A motor for rotating the rotary table is provided on the rotary table, and is connected to a motor gear meshing with the circumferential gear on the stationary table. An upper arm is supported tiltably on the rotary table, and has an upper end on which a front arm is supported. The front arm carries at its free end a working member, such as a welding torch. Another motor is provided on the upper arm for tilting it. A tension spring is disposed in the stationary table and has one end connected to the lower end of the upper arm, and another end connected to the stationary table at a point thereof about which the rotary table is rotatable. The tension spring serves to reduce the load on the motor which tilts the upper arm.

Abstract: A welding torch for use in a welding robot is prevented from being deformed or otherwise damaged on collision with the work while the welding robot is being taught. The welding torch comprises a housing adapted to be supported at a distal end of the robot arm, a torch nozzle axially movably and rotatably supported at a distal end of the housing, a shaft axially movably and rotatably mounted in the housing and movable in response to rotation and/or axial movement of the torch nozzle, and a switch or switches mounted in the housing and actuatable in response to rotation and/or axial movement of the shaft for generating a signal to stop the movement of the robot arm. When the torch nozzle collides with the work, the switch means is actuated to stop the movement of the robot arm.

Abstract: A swiveling apparatus has installed electric cables which electrically interconnect equipment in a factory to equipment which is supported by the apparatus. The apparatus includes a fixed part which contains a cylindrical portion which is engaged via bearings with a rotating portion of a rotating part. A plurality of right-hand wound springs and left-hand wound springs are alternately disposed along a periphery of the cylindrical portion of the fixed part and extend between ribs and a base portion of the fixed part. A plurality of electric cables extend between a connector, which is connected to electric cables of the outside equipment, and the equipment which is supported by the rotating part. The springs are of sufficient length so that the rotating part can be rotated through a predetermined angle.

Abstract: A limit switch mechanism includes a limit switch disposed in confronting relation to a cam mounted on a switch drive shaft. The limit switch is actuatable by the cam when the switch drive shaft is angularly moved about its own axis through a predetermined angle. The limit switch has a longitudinal axis extending substantially parallel to the axis of the switch drive shaft, and is disposed in the vicinity of the switch drive shaft. The limit switch is actuated by being pushed by a limit switch arm extending from a cam arm actuatable by the cam and located more closely than the cam arm to the switch drive shaft.
