  How should a robot direct active vision so as to ensure reliable grasping? We
answer this question for the case of dexterous grasping of unfamiliar objects.
By dexterous grasping we simply mean grasping by any hand with more than two
fingers, such that the robot has some choice about where to place each finger.
Such grasps typically fail in one of two ways, either unmodeled objects in the
scene cause collisions or object reconstruction is insufficient to ensure that
the grasp points provide a stable force closure. These problems can be solved
more easily if active sensing is guided by the anticipated actions. Our
approach has three stages. First, we take a single view and generate candidate
grasps from the resulting partial object reconstruction. Second, we drive the
active vision approach to maximise surface reconstruction quality around the
planned contact points. During this phase, the anticipated grasp is continually
refined. Third, we direct gaze to improve the safety of the planned reach to
grasp trajectory. We show, on a dexterous manipulator with a camera on the
wrist, that our approach (80.4% success rate) outperforms a randomised
algorithm (64.3% success rate).
