WebbThe aim of this study was to describe in-hand manipulation skills with regards to translation, rotation and shift movements to cover all aspects of in-hand manipulation in 4 and 5-year-old children, through the use of an observation checklist compiled by the researchers, from non-standardised activities and standardised tests published in the … WebbHand grasp has been studied for decades to better under-stand the use of human hands [23, 27, 26, 2, 13]. Grasp taxonomies have also been proposed to facilitate hand grasp analysis [5, 17, 10]. Cai et al. [3] first developed techniques to recognize hand grasp types in everyday hand manipulation tasks recorded with a wearable RGB camera and ...

Webbhand manipulation works in this subsection. To achieve in-hand manipulation, multi-ngered dexterous hands utilize the redundancy of the ngers to move the object while holding it. Under-actuated hands are able to leverage model based control [17] for in-hand manipulation tasks. There are also task-specic designs of under-actuated hands … Webbadvances in hand design for in-hand manipulation focus on increasing finger dexterity [8], [19]–[22]. However, the palm’s surface takes on new functions during in-hand manipulation: a surface on which to slide or tip the object. While some work has been done investigating the effect of palm design on in-hand manipulation [8], [23], [24 ...

WebbB. Coding In-Hand Manipulation Skills The first behavior we chose to replicate, after observing our own hands, was to repeatedly rotate a cube counter-clockwise. To faithfully mimic this behavior on the robot hand, we did not restrict ourselves to the common practice of fingertip-only contacts. As we shall see later, this is crucial to the ...
