1. A medical system comprising:
- an entry guide;
a plurality of articulated instruments extending through the entry guide;
an input device associated with an associated articulated instrument of the plurality of articulated instruments; and
a controller configured to command manipulation of the associated articulated instrument according to a weighted average, using non-zero weights, of a commanded pose of the associated articulated instrument and a preferred pose of the associated articulated instrument, wherein the commanded pose of the associated articulated instrument is commanded by manipulation of the input device by an operator.

Abstract
A medical robotic system includes an entry guide with articulated instruments extending out of its distal end. A controller is configured to command manipulation of one of the articulated instruments towards a state commanded by operator manipulation of an input device while commanding sensory feedback to the operator indicating a difference between the commanded state and a preferred pose of the articulated instrument, so that the sensory feedback serves to encourage the operator to return the articulated instrument back to its preferred pose.
