Safety Intelligence And Legal Machine Language: Do We Need Three Laws Of Robotics?, Chien Hsun Chen, Y. H. Weng, C. T. Sun Aug 2009

Safety Intelligence And Legal Machine Language: Do We Need Three Laws Of Robotics?, Chien Hsun Chen, Y. H. Weng, C. T. Sun

Chien Hsun Chen

In this chapter we will describe a legal framework for Next Generation Robots (NGRs) that has safety as its central focus. The framework is offered in response to the current lack of clarity regarding robot safety guidelines, despite the development and impending release of tens of thousands of robots into workplaces and homes around the world. We also describe our proposal for a safety intelligence (SI) concept that addresses issues associated with open texture risk for robots that will have a relatively high level of autonomy in their interactions with humans. Whereas Isaac Asimov’s Three Laws of Robotics are frequently …


Strongly Coupled Computation Of Material Response And Nonequilibrium Flow For Hypersonic Ablation, Alexandre Martin, Iain D. Boyd Jun 2009

Strongly Coupled Computation Of Material Response And Nonequilibrium Flow For Hypersonic Ablation, Alexandre Martin, Iain D. Boyd

Alexandre Martin

A one-dimensional material response implicit solver with surface ablation and pyrolysis is strongly coupled to LeMANS, a CFD code for the simulation of weakly ionized hypersonic flows in thermo-chemical non-equilibrium. Using blowing wall boundary conditions and a moving mesh algorithm, the results of a strongly coupled solution of a re-entry problem are presented, using the well defined case of the IRV-2 vehicle. Results are compared to other coupled codes and show good agreement with published numerical results.


An Immune Self-Adaptive Differential Evolution Algorithm With Application To Estimate Kinetic Parameters For Homogeneous Mercury Oxidation, Chunping Hu, Xuefeng Yan Apr 2009

An Immune Self-Adaptive Differential Evolution Algorithm With Application To Estimate Kinetic Parameters For Homogeneous Mercury Oxidation, Chunping Hu, Xuefeng Yan

Chunping Hu

A new version of differential evolution (DE) algorithm, in which immune concepts and methods are applied to determine the parameter setting, named immune self-adaptive differential evolution (ISDE), is proposed to improve the performance of the DE algorithm. During the actual operation, ISDE seeks the optimal parameters arising from the evolutionary process, which enable ISDE to alter the algorithm for different optimization problems and improve the performance of ISDE by the control parameters’ self-adaptation. The performance of the proposed method is studied with the use of nine benchmark problems and compared with original DE algorithm and other well-known self-adaptive DE algorithms. …


Kpca-Rvm Modeling Method And Its Application For Soft Sensor, Xuefeng Yan, Jia Chen, Chunping Hu, Feng Qian Mar 2009

Kpca-Rvm Modeling Method And Its Application For Soft Sensor, Xuefeng Yan, Jia Chen, Chunping Hu, Feng Qian

Chunping Hu

A novel modeling method integrated KPCA with RVM is proposed. Firstly, kernel primary component analysis (KPCA) is employed to identify the principal components from the nonlinear transform data of independent variables, which are regarded as character variables. Then, regression between character variables and dependent variables is done based on RVM, and the optimal number of the character variables is adaptively determined according to the generalization performance of the regression model. Thus, KPCA-RVM method can eliminate the disturbance of redundant information and achieve the best nonlinear model with good generalization performance. Finally, the method of KPCA-RVM is demonstrated by a 4-CBA's …


Toward The Human-Robot Co-Existence Society: On Safety Intelligence For Next Generation Robots, Chien Hsun Chen, Y. H. Weng, C. T. Sun Jan 2009

Toward The Human-Robot Co-Existence Society: On Safety Intelligence For Next Generation Robots, Chien Hsun Chen, Y. H. Weng, C. T. Sun

Chien Hsun Chen

Technocrats from many developed countries, especially Japan and South Korea, are preparing for the human-robot co-existence society that they believe will emerge by 2030. Regulators are assuming that within the next two decades, robots will be capable of adapting to complex, unstructured environments and interacting with humans to assist with the performance of daily life tasks. Unlike heavily regulated industrial robots that toil in isolated settings, Next Generation Robots will have relative autonomy, which raises a number of safety issues that are the focus of this article. Our purpose is to describe a framework for a legal system focused on …
