In addition to being able to retrieve objects, the manipulator may be a pilot's second best friend after the tether handler. In some situations when the tether is stuck or wrapped around something, you may not be able to unstick it by piloting alone.
In this exercise, use the manipulator to "manage" the tether. Ideally, you can find something to wrap the tether around and then rather than navigating the ROV to clear the wrap or tangle, use the manipulator to do so. If you don't have something to wrap the tether around, you can practice for this scenario by tying a semi-tight knot in the tether (do not exceed the tether's minimum bend radius of about 75 mm (3 inches)). Use the manipulator to try to loosen the knot..
