Abstract
The invention provides a method of positioning a robot intended to perform inspection and maintenance operations within a nuclear plant, and especially within a vessel of a pressurized-water reactor. The robot, which comprises an articulated arm, is controlled so that it initially attaches its head at one end of the arm to a support point having known coordinates. Then, supported on this point, the robot brings and attaches a foot-plate at the other end of the arm to a working support position having known coordinates adjacent the access opening of the vessel. The head is then released and the robot operated to move and position the head through the access opening and into the operating zone in the vessel.
