Movements of Individual Digits in Bimanual Prehension Are Coupled into a Grasping Component
The classic understanding of prehension is that of coordinated reaching and grasping. An alternative view is that the grasping in prehension emerges from independently controlled individual digit movements (the double-pointing model). The current study tested this latter model in bimanual prehension: participants had to grasp an object between their two index fingers. Right after the start of t...
متن کاملSensorimotor transformations during grasping movements
Sensorimotor transformations’ are processes whereby sensory information is used to generate motor commands. One example is the ‘visuomotor map’ that transforms visual information about objects to motor commands that activates various muscles during grasping movements. In the first study we quantified the relative impact (or ‘weighting’) of visual and haptic information on the sensorimotor trans...
متن کاملLearning Synergies between Pushing and Grasping with Self-supervised Deep Reinforcement Learning
Skilled robotic manipulation benefits from complex synergies between non-prehensile (e.g. pushing) and prehensile (e.g. grasping) actions: pushing can help rearrange cluttered objects to make space for arms and fingers; likewise, grasping can help displace objects to make pushing movements more precise and collision-free. In this work, we demonstrate that it is possible to discover and learn th...
متن کاملA neural network interface to the DIGITS Grasping System
A neural network-based interface between an operator and the DIGITS Grasping System is proposed, and the initial results of the network training are presented. The neural network is responsible for accepting the description of an object to be held in a power grasp and mapping this data into a set of actuator torques which will allow DIGITS to rmly grasp the object. In addition, the network shou...
متن کاملAdapting Preshaped Grasping Movements Using Vision Descriptors
Grasping is one of the most important abilities needed for future service robots. In the task of picking up an object from between clutter, traditional robotics approaches would determine a suitable grasping point and then use a movement planner to reach the goal. The planner would require precise and accurate information about the environment and long computation times, both of which are often...
