    Abstract: An apparatus is provided with position sensors. When the apparatus has moved one tubular into alignment with another tubular a button on a remote control console is pressed to memorize the position. After the next tubular has been gripped by the apparatus a "recall" button is pressed and the apparatus automatically moves the next tubular to the memorized position. This saves vital seconds in joining tubulars and also reduces the likelihood of threads being damaged due to misalignment of the tubulars.
