This
is the gripper of a Schilling Robotics Orion rate arm. The jaws on
this are of the overlapping digit type, allowing a good grip on irregular
shaped or cylindrical objects and used where a parallel type jaw will
lose its grip under load. This arm is fitted to a sub sea cable maintenance
vehicle and is often used to lift a cable from the sea bed to facilitate
cutting it prior to a repair. The increased use of rate arms may also
relate to the levels of operator skill needed - although a skilled
operator can use a position feedback arm to great effect and greatly
reduce the time needed to do any task, a less experienced operator
will take much longer and often causes damage to the manipulator,
the ROV and the work piece. With a rate arm
progress is slower but the less experienced operator has more time
to judge his next move |
| The
standard manipulator pair in the oil and gas industry is a 5-function
gripper on the left and a 6- or 7-function position feed back arm
on the right. This combination allows the ROV to grip onto part of
a BOP or the guide posts of a well guide base with its left arm and
perform its task with the right . The ROV shown on the right has just
this combination, although the right arm is a 6-function feedback
arm. |
