    grasps The planning method uses a unified treatment for all robotic hand models in the image even though the kinematic specifications are significantly different Optimization of underactuated hand designs We present a method for analysis and optimization of tendon based underactuated adaptive hands We have integrated the co actuation and compliance constraints together with contact friction constraints into a quasistatic equilibrium formulation Using this model we can build a solvable optimization problem to compute the hand design parameters that provide the best performance over a large set of grasping tasks We believe that for the class of adaptive underactuated hands the on line grasp planning effort traditionally carried out under tight time constraints and requiring extensive sensing capabilities can be replaced by off line optimization increasing hand performance over many grasping scenarios As a concrete example we have analyzed a simplified single tendon gripper model and have used the results of the optimization to construct a prototype capable of a wide range of grasps A Constrained Optimization Framework for Compliant Underactuated Grasping M Ciocarlie and P Allen Workshop on Underactuated Grasping 2010 pdf 1 3MB Data driven Optimization for Underactuated Robotic Hands M Ciocarlie and P Allen ICRA 2010 pdf 1 6MB Design and Analysis Tool for Underactuated Compliant Hands M Ciocarlie and P Allen IROS 2009 pdf 0 2MB Grasping and manipulation using soft fingertips The ability to create stable encompassing grasps with subsets of fingers is greatly increased by using soft fingertips that deform during contact and apply a larger space of frictional forces and moments than their rigid counterparts This is true not only for human grasping but also for robotic hands using fingerpads made of soft materials Here are examples of dynamic simulations of an anthropomorphic hand using soft fingertips for performing manipulation tasks In order to achieve computational rates needed for dynamic simulation I am using an analytical soft finger model that uses general expressions for non planar contacts of elastic bodies to account for the local geometry and structure of the bodies in contact Soft Finger Model with Adaptive Contact Geometry for Grasping and Manipulation Tasks M Ciocarlie C Lackner and P Allen World Haptics 2007 Best Student Paper Award pdf 1 23 MB Another approach to building soft finger contact models uses Finite Element Analysis FEA to explicitly compute fingertip deformation This method is computationally expensive but makes no assumptions regarding the geometry of the fingerpad and the results are very accurate from a physical point of view It can also be used to compute the deformation of the fingertip in response to frictional forces and moments We have applied this method for performing grasp analysis on pinch grasps using robotic hands equipped with fingers coated in a thin layer of rubber More details including the grasp analysis method quality metrics as well as the finite element method used can be found in Grasp Analysis Using Deformable Fingers M Ciocarlie A Miller and P Allen IROS 2005 pdf 0 6 MB Images snapshot
