TL;DR: The solution is based on two camera sensors which enable intelligent manipulation on 3D basis and will be applied and verified on KUKA robot for "pick and place" cases.
Abstract: In project implementation by the Centre for management of technical, environmental and humane risks research for permanent development of production and products in machinery industry, specifically for the activity 3.2. Which deals with automation and robotization of production systems, the main target is increasing degree of automation with focus on intelligent manipulation on 3D basis. This target is being applied by large scale use of robots for various manipulation and technological application. The solution is based on two camera sensors which enable intelligent manipulation on 3D basis. For this purpose a sensor and software for object recognition have been specified. The solution will be applied and verified on KUKA robot for "pick and place" cases.

TL;DR: In this paper, the authors discuss the Japanese context of Society 5.0, which is based on a society-centered approach to take advantage of technological advances to finally solve the problems that currently threaten Japan, such as aging, birth rates and lack of competitiveness, among others.
Abstract: This document discusses the Japanese context of Society 5.0. Based on a society-centered approach, Society 5.0 seeks to take advantage of technological advances to finally solve the problems that currently threaten Japan, such as aging, birth rates and lack of competitiveness, among others. Additionally, another objective is to contribute to the progress of the country and develop the foundations for a better world, in which no individual can be excluded from the technological advances of our current society, to achieve this goal, the Sustainable Development Goals (SDG) have been developed. SDGs seek to assess the methods of use of modern technology and thus find the best strategies and tools to use it in a way that guarantees sustainability within the framework of a new society that demands constant renovations.

TL;DR: In this article, a bendable biomimetic whisker mechanoreceptor was designed for robotic tactile sensing, which can convert external mechanical stimuli into electrical signals without a power supply, which is conducive to its widespread applications in robots.
Abstract: Touch sensing is among the most important sensing capabilities of a human, and the same is true for smart robotics. Current research on tactile sensors is mainly concentrated on electronic skin (e-skin), but e-skin is prone to be easily dirtied, damaged, and disturbed after repeated usage, which greatly limits its practical applications in robotics. Here, by mimicking the way that animals explore the environment using hair-based sensors, a bendable biomimetic whisker mechanoreceptor (BWMR) is designed for robotic tactile sensing. Owing to the advantages of triboelectric nanogenerator technology, the BWMR can convert external mechanical stimuli into electrical signals without a power supply, which is conducive to its widespread applications in robots. Because of the leverage effect of the whisker, the BWMR can distinguish an exciting force of 1.129 μN by amplifying external weak signals, which can be further improved by increasing the whisker length. Real-time sensing is demonstrated using a BWMR, exhibiting its potential for robotic tactile systems.

TL;DR: In this article, the problem of determining the repeatability positioning error of a robot at any given point in its workspace without the necessity of conducting time-consuming measurements while routing a precise surface of repeatability is addressed.
Abstract: Purpose – The purpose of the following work was to work out the dependency to allow for the determination of the repeatability positioning error value of the robot at any given point in its workspace, without the necessity of conducting time-consuming measurements while routing a precise surface of repeatability positioning. Design/methodology/approach – The presented dependency permits for the possibility to determine, even at the planning phase, the optimal connection point in the workspace, ensuring the best parameters for the process of machine assembly, without needless overestimation of precision of the utilized equipment. To solve the task the sequential quadratic programming (SQP) method implemented in the MATLAB(R) environment was used. To verify the hypothesis of the compatibility of the empirical distribution with the hypothetical distribution of the robot’s positioning error, the Kolmogorov test was used. Findings – In this paper, it has been demonstrated theoretically and experimentally that ...
