The wide spread use of 3D acquisition devices with highperformance processing tools has facilitated rapid generation of digital twin models for large production plants and factories for optimizing work cell layouts and improving human operator effectiveness, safety and ergonomics. Although recent advances in digital simulation tools have enabled users to analyze the workspace using virtual huma...

We agree with Robertson that our new view on grasping is a description of motor behaviour rather than offering any insight into the nature of the neural processing underlying this behaviour. However, neurophysiologists might be inspired by our new view to ask other questions, do other experiments, and analyse these differently. In this way, they could generate new insights about the neural cont...

The century of complexity has come. Many people write and speak about complexity. The statement of the great physicist Stephen Hawking, “I think the next century will be the century of complexity,” in his ‘millennium’ interview on January 23, 2000 (San Jose Mercury News) became a widely cited prophecy. The face of science has changed (see cartoon in Fig. 1). Surprisingly, when we start asking a...

Craighero et al. showed that grasping movements were initiated more quickly when the goal object shared the same orientation as a previously seen 'prime' object. Because the goal object was never visible in these experiments, however, it is unclear whether the data should be construed as evidence for a general visuomotor priming effect (as the authors contend), or only as evidence for a more sp...

The main purpose of this paper is to determine what joints are most strained in the proposed underactuated finger by adaptive neuro-fuzzy methodology. For this, kinetostatic analysis of the finger structure is established with added torsional springs in every single joint. Since the finger’s grasping forces depend on torsional spring stiffness in the joints, it is preferable to determine which ...

A versatile robot manipulator is based on techniques of computer vision and neural network learning. For grasping objects four principal tasks have to be done in a cycle | detect the desired object and the grasping ngers in the images, evaluate the spatial relationship wrt. grasping stability, choose a more stable grasping pose (if possible), and move the manipulator to it. In this work we focu...

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...

We present a self-contained, soft robotic hand composed of soft pneumatic actuator modules that are equipped with strain and pressure sensing. We show how this data can be used to discern whether a grasp was successful. Colocating sensing and embedded computation with the actuators greatly simplifies control and system integration. Equipped with a small pump, the hand is self-contained and need...

[Purpose] To test the hypothesis that toe grasping strength is associated with daily physical activity in older adults. [Subjects] Fifty-seven Japanese women, aged 52-78 years, volunteered. [Methods] Toe grasping and knee extension strength were measured. Physical activity was also measured, using an accelerometer, and the total duration of each level of exercise intensity (light, moderate, and...
