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.
Claims15
A medical system comprising:
- a medical device;
- an input device that is operated by an operator to output a commanded state of the medical device;
- a pose selector that outputs a preferred pose of the medical device, the preferred pose being different, at a time of pose selection, than the commanded state and a current pose of the medical device, the preferred pose being one of a default pose and an operator defined pose, the default pose fixed for the medical device, the operator defined pose having been defined by the operator of the input device;
- and
- a control system for controlling movement of the medical device from the current pose of the medical device in response to the commanded state and for commanding a biasing force to be applied to the input device such that the biasing force increases whenever a difference between the commanded state and the preferred pose increases.
