Weber’s law is among the basic psychophysical laws of human perception. It determines that human sensitivity to change along a physical dimension, the just noticeable difference (JND), is linearly related to stimulus intensity. Conversely, in direct (natural), visually guided grasping, Weber’s law is violated and the JND does not depend on stimulus intensity. The current work examines adherence...

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 ...

Vision-based pose detection and grasping complex-shaped thin objects are challenging tasks. We propose an architecture that integrates the Generative Grasping Convolutional Neural Network (GG-CNN) with depth recognition to identify a suitable grasp pose. First, we construct training dataset data augmentation train GG-CNN only RGB images. Then, extract segment of tool using color segmentation me...

In this paper, the robot grasping for stacked objects is studied based on object detection and order planning. Firstly, a novel classification network (SOCN) proposed to realize recognition. The takes into account visible volume of further adjust its inverse density parameters, which makes training process faster smoother. At same time, SOCN adopts transformer architecture has self-attention me...

Grasping is one of a few adaptive mechanisms that, in conjunction with clinging, hooking, arm swinging, adhering, and flying, allowed for incursion into the arboreal eco-space. Little research has been done that addresses grasping as an enhanced manual ability in non-mammalian tetrapods, with the exception of studies comparing the anatomy of muscle and tendon structure. Previous studies showed ...

The purpose of this paper is to show the feasibility of grasping force control by feeding back signals of the developed micro-laser Doppler velocimeter (μ-LDV) and by discriminating whether a grasped object is slipping or not. LDV is well known as a high response surface velocity sensor which can measure various surfaces-such as metal, paper, film, and so on-thus suggesting the potential applic...
