A quality measure for compliant grasps

This paper presents a systematic approach for quantifying the quality of compliant grasps. Appropriate tangent and cotangent subspaces to the object's configuration space are studied, from which frame-invariant characteristic compliance parameters are defined. Physical and geometric interpretations are given to these parameters, and a practically meaningful method is proposed to make the parameters comparable. A frame-invariant quality measure is then defined, and grasp optimization using this quality measure is discussed with examples.
