Planning optimal grasps means that it should be possible to find either some points or surface areas on the object where it is possible to apply some forces by using the fingers of a robotic hand so as to obtain stable grasps. A grasp is stable when the fingers resist to external forces applied on the object. If the object is not known a-priori, the operation of finding a stable grasp becomes more complicated.

A method where the above described object reconstruction process guides the multi- fingered robotic hand to grab the object in a (sub)optimal configuration is proposed here, here and here. This method allows to perform the object reconstruction process in parallel with the optimal grasp planner. In this way, the total time to perform a grasp is reduced with respect to the methods presented in the literature. Moreover, the movements of the fingers can be compared with the ones performed by the human hand, as highlighted here.
