Abstract: A surgical robot includes a manipulator arm having a tip end side to which a surgical instrument is attached, a controller configured or programmed to perform a control to operate the manipulator arm to which the surgical instrument is attached, and a teaching unit to teach a teaching point in a space in which the manipulator arm operates. The controller is configured or programmed to set a virtual contact prohibited space in a space around a contact prohibited object based on a plurality of the teaching points taught using the teaching unit.

Abstract: A robotic surgical system includes a controller configured or programmed to perform an arm interference avoidance control to move a second manipulator arm relative to a first manipulator arm such that a reference line moves along an outer edge of an approach prohibited range of a first manipulator arm when a second manipulator arm approaches within the approach prohibited range.

Abstract: A robotic surgical system according to this disclosure includes a controller configured to control at least one of the first driver and the second driver to maintain a distance between the first operation unit and the second operation unit when a third operation to move the endoscope by the first operation unit and the second operation unit is received

Abstract: A process for desulfurizing a molten iron alloy in which a desulfurizing agent is applied to the molten iron alloy under agitation. Concurrently, a gas containing a hydrocarbon gas is blown onto the bath surface of the molten iron alloy, or a substance generating a hydrocarbon gas is added to the bath surface.

Abstract: In a batting practice range where a pitching machine is installed to automatically pitch a ball toward a batter's box, hitting zones such as out zones, hit zones and home run zones are provided in front of the batter's box to detect a ball driven into either one of them from the batter's box for judging the ball as "Out", "Hit" or "Home run". An upright board is installed behind the batter's box and provided with a strike sensor for detecting vibration caused by a ball pitched by the pitching machine and struck the upright board and for judging the ball as "Strike". If a ball pitched by the pitching machine is not detected as any one of "Out", "Hit", "Home run" or "Strike" within a predetermined time, the ball is Judged as a foul ball.
