A water cooling device of a vertical multi-cylinder engine includes a cylinder block (1) one side wall of which is provided with a side water passage (3) running along a longitudinal direction of the cylinder block (1). The cylinder block (1) has an interior area provided with a cylinder jacket (4). Cooling water from a radiator is introduced into the cylinder jacket (4) through the side water passage (3). The side water passage (3) has an outlet (5) toward a lower portion of the cylinder jacket (4).

A robot controller executes an operating program, calculates a position and posture of a robot, and sends the position and posture information to a personal computer (PC). At the PC side, on the basis of this position and posture information, animation display information of a work cell including the position and posture of the robot is created and then sent to a teaching pendant. In the teaching pendant, the animation display information is received, and an animation image is displayed on a display section. Until the operating program is terminated, this operation is performed so that an operating animation of the robot is displayed on the display section of the teaching pendant.

A robot off-line simulation apparatus that allows a person to know an optimum placement for a robot, an operation margin index, etc. before going to an actual working site. Provisional robot placing positions are selected using data about a given sequence of task points (operation path), etc. The conditions for selection are (i) that solution to the inverse kinematics should be found regarding the entire sequence of task points, (ii) that the robot should not interfere with a peripheral device, and (iii) that regarding all the axes of the robot, the operation margin index should satisfy a criterion value. Simulation is performed according to operation programs under the condition that the robot is placed at each of the provisional placing positions, where data about cycle time, duty, energy value, change in acceleration/speed, etc. is collected. Using the collected data, evaluation of operation is performed regarding each of the provisional placing positions, and those provisional placing positions which allow good operation are identified as placing positions ensuring the robot operation. Further, using an evaluation function in which each aspect is given a weighting, the placing positions ensuring the robot operation are reduced to optimum placing positions ensuring the robot operation.

The present invention corrects a teaching point set in a robot movement control program to another position using jog-feed buttons. A robot tool is moved by jog-feed buttons using a jog-feed command unit toward a position to which a teaching point is to be corrected. When the position of the tool approaches any teaching point contained in a movement command program, the robot is automatically shifted to the teaching point to be corrected in the movement command program. When the teaching point to be corrected is found, correction of a teaching point from the closest teaching point to the position to be corrected is then performed.

The robot control system of the present invention stores the robot's initial state data memory prior to engaging in an operation. During a manual movement operation, the robot is started at a predetermined low speed so that the operator may easily observe its movement and take corrective action thereby improving safety. While the robot is operating at this low speed a recovery command may then be issued by the operator from a recovery command unit when it is observed that the robot is moving inappropriately. Upon detection of the recovery command, a recovery control unit then operates causing the robot to recover its attitude and position as defined by the initial state data stored in memory. However, if a predetermined period of time elapses without a recovery command being issued, then speed of the robot is gradually increased from the predetermined low speed until reaching a predetermined target speed. Thereafter, the robot is manually controlled to operate at a constant speed.

A method of inducing arc generation in arc welding between a head of a wire and a workpiece, such that a robot supports a welding torch, thereby causing the head of the wire to be brought near a welding start position on a workpiece. However, if there is a failure to generate an arc between the head of the wire at the position and the workpiece within a predetermined time, at least one cycle is repeated of a sequential retrial motion, in which first the robot is made to move to cause the head of the wire to be moved at a predetermined speed from a position close to the present welding start position to another position away from the position by a predetermined distance, and then the robot is made to move in the opposite direction to cause the head of the wire to be moved at a predetermined speed toward the welding start position. Then, when an arc generation signal is detected during repeated performance of the retrial motion, the retrial motion is stopped, and a predetermined welding for the workpiece is started.

A robot control apparatus programmably controls a taught/playback-type robot. The control apparatus has processing control means (CPU) which converts a group of position data contained in a plurality of robot command data inputted from a teaching panel into set-type command data together with other robot command data, stores the converted command data in a data memory (RAM), and creates a robot motion program by editing the command data.
