Grasping of Unknown Object Imitating Human Grasping Reflex
This paper presents a grasping strategy of unknown objects imitating human grasping reflex for anthropomorphic robot hands. In the proposed grasping, each joint of the thumb and the fingers is controlled independently using the contact force affecting its adjacent fingertip side link. By setting a suitable contact force, both fingertip grasping and enveloped grasping with uniform grasping force...
متن کاملFuzzy Logic Control for Grasping 3D Objects with Sliding Contacts
The overwhelming complexity of the grasping process and imprecise knowledge about articulated robot hand systems leads to a certain control problem. In order to solve these problems, the paper proposes a new design of fuzzy control approach for two fingered robot hand, which is able to control simultaneously grasping and slipping of 3D fragile objects in unstructured environment. In this contex...
متن کاملGrasping on Contact Primitives by Fingertip Surface Optimization
GRASPING is an essential ability that enables the robot to physically interact with the world. Contact-based grasping [1], which explicitly considers the contacts made by a grasp, has been widely studied to address various aspects of grasping [2, 3]. Contact modeling is one of the basic building blocks for the research of contact-based grasping. Dependent on the friction and softness at contact...
متن کاملUnknown Object Grasping Strategy Imitating Human Grasping Reflex for Anthropomorphic Robot Hand
This paper presents a strategy meant to allow anthropomorphic robot hands to grasp objects of unknown shape in imitation of the human grasping reflex. A 10-month-old baby may bend his/her thumb and four fingers in an attempt to grasp an object when it comes in contact with the palm. After grasping it, if the object is attempted to be removed from the baby’s hand, the baby holds the object more ...
متن کاملInfluence of Permethrin and Cypermethrin on Behavior in the Mouse
Permethrin and Cypermethrin are synthetic pyrethroids, belonging to a group of insecticides with low mammalian toxicity and high insecticidal activity. The present study evaluated sub-acute toxicity of dermally administrated permethrin and cypermethrin in mice. Behavioral examination included assessments of lethality, weight gain, grooming, analgesymetry, anxiety, grasping, motor activity, and ...
