Grip force adaptation in manipulation activities performed under different coating and grasping conditions.
The aim of the study was to evaluate grip force (GF; normal component of hand-object interaction) adaptation across different manipulation conditions. We hypothesized (1) that the absolute safety margin (the difference between the exerted GF and the minimum GF that prevents slippage; absolute SM), rather than the relative SM (the same difference relative to the minimum GF required), could be an...
متن کاملFixation locations when grasping partly occluded objects.
When grasping an object, subjects tend to look at the contact positions of the digits (A. M. Brouwer, V. H. Franz, D. Kerzel, & K. R. Gegenfurtner, 2005; R. S. Johansson, G. Westling, A. Bäckström, & J. R. Flanagan, 2001). However, these contact positions are not always visible due to occlusion. Subjects might look at occluded parts to determine the location of the contact positions based on ex...
متن کاملTangential torque effects on the control of grip forces when holding objects with a precision grip.
When we manipulate small objects, our fingertips are generally subjected to tangential torques about the axis normal to the grasp surface in addition to linear forces tangential to the grasp surface. Tangential torques can arise because the normal force is distributed across the contact area rather than focused at a point. We investigated the effects of tangential torques and tangential forces ...
متن کاملCompliant Grasping Force Modeling for Handling of Live Objects
This paper inodels quasi-statically the force acting on an object by a rotating flexible finger. As compared to fingers with multiple active joints, flexible fingers have many potential advantages; specifically, they are lightweight and have no relative individual moving parts in each of the fingers. Their ability to accommodate a limited range of varying sizes, shapes, and the natural reaction...
متن کاملOptimization of grasping by using a required external force set
In this paper, we consider an optimization of grasping by using a required external force set. By using the set, we can not only deal with whatever a desired grasp is, such as force closure or equilibrium grasp, but also evaluate the magnitudes of the resistible external forces and moments. Then, we define an optimization problem from the viewpoint of decreasing the magnitudes of the contact fo...
