The method used is an Inductive Approach where it starts by looking at the current state of the South African Manufacturing Industry and then moves to how Reconfigurable Supply Chains can assist to improve the South African Press Tool industry's competitiveness. Globalization has created new views of the Manufacturing industry specifically looking at the Press Tool Industry which sees the South African Manufacturing Industry currently being ranked 24th in the world. Authors recommend that future supply chains take reconfigurability into consideration to enhance the survivability of the South African Press Tool industry in the global environment that is driven by very tough competition, shorter marketing opportunities, frequent product introductions and rapid changing customer product demands. Supply Chain Management is coupled by various approaches such as Internet based supply chain management, Enterprise Resource Planning and Agent Oriented supply chain management. This paper will compare and contrast the available approaches and then select the approach that will best enhance competitiveness of the South African Press Tool Manufacturing Industry.","PeriodicalId":143604,"journal":{"name":"2013 6th Robotics and Mechatronics Conference (RobMech)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115382637","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, for purposes of control systems design, they are usually treated as linear systems within a defined operating range. The process of modeling and linearization is complex, costly and often inaccurate due to uncertainties in system parameters. In this paper, a laboratory Ball on Wheel system is implemented, modeled and linearized. Thereafter, a traditional PID controller is designed and performance analyzed. Intelligent control, utilizing Neural Networks (NN) is also considered for control of the non-linear system. The control systems are further implemented within an industrial controller, allowing further performance analysis.","PeriodicalId":143604,"journal":{"name":"2013 6th Robotics and Mechatronics Conference (RobMech)","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128305309","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The focus of this paper is on the challenges of spatial manipulators with large number of degrees of freedom (dof's). For obstacle avoidance in three-dimensional workspaces, a penalizing scheme is proposed. Based on variational calculus, this approach involves the formulation of a functional, which is minimized to get an optimal path. The minimization of the objective function results in a boundary value problem (BVP), which is solved using relaxation method. A variety of examples are presented to demonstrate the approach and to show its efficiency in providing good quality paths. The paper also includes systematic procedures for initial path generation and the inverse kinematics for serial redundant manipulators. These schemes reduce the preprocessing task to a great extent and add to the efficacy of the proposed method.","PeriodicalId":143604,"journal":{"name":"2013 6th Robotics and Mechatronics Conference (RobMech)","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128116568","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Bright","doi":"10.1109/ROBOMECH.2013.6685485","DOIUrl":"https://doi.org/10.1109/ROBOMECH.2013.6685485","url":null,"abstract":"Mobile robots have demonstrated their versatility in a wide range of applications and situations. However, they are limited due to their reliance on traditional energy sources such as electricity and petroleum which cannot always provide a convenient energy source in all situations. Moreover, in a more eco-conscious modern world, these energy sources, which require the burning of a fuel in order to generate the output of electricity, are increasingly being shunned in favour of cleaner alternative energy sources such as solar energy. This study seeks to demonstrate the viability of an alternative, renewable, energy source for the operation of mobile robots. For the purposes of this study, an Industrial Mobile Robot Platform (IMRP) was designed that would run on solar power making use of an array of photovoltaic panels. In order to overcome the limitations of solar power, which is dependent on the availability of sunshine and thus cannot provide a constant source of energy, an energy storage medium was employed making use of metal hydrides. The advantage of this medium is that it is able to store energy in the form of hydrogen produced from solar energy, thus providing a reliable and constant energy source to power the IMRP. The IMRP was fabricated to run on hydrogen fuel cells using a low-pressure metal hydride hydrogen storage system that can store more energy on board than current conventional energy storage methods. The results show that solar energy can indeed provide a viable renewable energy source to power IMRPs, and that its limitations due to solar being an inconstant energy source can be overcome by the use of energy storage materials in the form of metal hydrides that store energy produced from solar power, and thereby satisfying the constant demand for energy.","PeriodicalId":143604,"journal":{"name":"2013 6th Robotics and Mechatronics Conference (RobMech)","volume":"55 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121873717","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In order to carry out its mandate of improving the quality of life of South African citizens, the Council for Scientific and Industrial Research (CSIR) is undertaking research into how these accidents can be mitigated. One such method is the use of sensor equipped robotic platforms. The CSIR's mine safety platform is a robotic system for inspecting the working area of hard-rock mines to determine areas of rock fall risk. The mine safety platform uses two sensors to locate unstable areas of the hanging-wall, the 3D-thermal sensor and the wall stability assessor. The robot and its safety sensors have been tested in the CSIR's re-configurable stope test facility that enables the testing of mine equipment and machinery in a variety of simulated mine environments without the arduous and costly trips underground to various locations to encounter the various scenarios that the equipment needs to deal with.","PeriodicalId":143604,"journal":{"name":"2013 6th Robotics and Mechatronics Conference (RobMech)","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130524315","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Hierarchical Temporal Memory (HTM) is a proposed model within the field of neuromorphic engineering. It describes a top down approach to understanding how the human brain performs higher reasoning and has application as a machine-learning algorithm. Final results displayed an increase in permanence values associated with the learning of the input pseudo-sensory signal and the system was able to accurately recognize the input signal with up to twenty percent of the binary data randomly modified. These results demonstrated conclusive evidence that HTM is a possible choice when machine intelligence is a system requirement.","PeriodicalId":143604,"journal":{"name":"2013 6th Robotics and Mechatronics Conference (RobMech)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121844223","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Amidst numerous optical manufacturing techniques, single-point diamond turning is widely employed in the making of contact lenses due to its capability of producing optical surfaces of complex shapes and nanometric accuracy.
