This paper studies a variant of the container loading problem in which to the classical geometric constraints of packing problems we add other conditions appearing in practical problems, the multidrop ...
Then we propose a GRASP algorithm that solves the different types of multi-drop constraints and also includes other types of realistic constraints such as full support of the boxes and load bearing strength ...

Our resulting algorithm can determine if a grasp is passively stable, solve for equilibrium contact forces and compute optimal actuator commands for stability. ...
We thus introduce a convex relaxation method, along with an algorithm that successively refines this relaxation locally in order to obtain solutions to arbitrary accuracy efficiently. ...
While the runtime of our algorithm currently is too large for online grasp planning with more than a few contacts we see the main practical relevance of our method in enabling practitioners to understand ...

In this paper we focus on the following problem in multi-fingered robotic grasping: assuming that an external wrench is being applied to a grasped object, will the contact forces between the hand and the ...
Such passive effects include for example joints that are driven by highly geared motors (a common occurence in practice) and thus do not back drive in response to external torques. ...
To measure the maximum force that a grasp can resist in a certain direction, we manually apply a load to the grasped object using a Spectra wire in series with a load cell (Futek, FSH00097). ...
