PURPOSE:To provide the manpower-saving and cost effective underwater working robot which can be safely and rapidly carried into and out of an intake channel without an operation to mount and dismount a weight by a diver and the method for carrying this robot into and out of a carrying-in/out port. CONSTITUTION:This underwater robot for removing shells is an underwater float of a vertically long rectangular shape, is maintained in a horizontal posture in the water by balancing of its own weight and buoyancy and is remote-controlled within the intake channel via a cable 2 extending through the carrying-in/out port on the ground. The robot described above has the weight 3 fixed near the end opposite to the mounting end of the cable 2 of the robot 1, a freely expandable and contractable air bag 4 and a long-sized air feed and discharge hose 6 which is connected at the bottom end to the air bag 4 and extends from above the ground to the bottom of the intake channel. The air in the air bag 4 is removed and the underwater robot 1 is hung in a vertical posture and is seated on the bottom of the intake channel by means of ropes at the time of carrying-in. The air is then injected into the air bag 4 through the air feed and discharge hose 6 to put the underwater robot 1 into the horizontal posture; thereafter, the robot is moved in the intake channel. |
