Ground Robotic Hand Applications for the Space Program study (GRASP)

This document reports on a NASA-STDP effort to address research interests of the NASA Kennedy Space Center (KSC) through a study entitled, Ground Robotic-Hand Applications for the Space Program (GRASP). The primary objective of the GRASP study was to identify beneficial applications of specialized end-effectors and robotic hand devices for automating any ground operations which are performed at the Kennedy Space Center. Thus, operations for expendable vehicles, the Space Shuttle and its components, and all payloads were included in the study. Typical benefits of automating operations, or augmenting human operators performing physical tasks, include: reduced costs; enhanced safety and reliability; and reduced processing turnaround time

A METHODOLOGY FOR AUTONOMOUS ROOF BOLT INSTALLATION USING INDUSTRIAL ROBOTICS

The mining sector is currently in the stage of adopting more automation, and with it, robotics. Autonomous bolting in underground environments remains a hot topic for the mining industry. Roof bolter operators are exposed to hazardous conditions due to their proximity to the unsupported roof, loose bolts, and heavy spinning mass. Prolonged exposure to the risk inevitably leads to accidents and injuries. The current thesis presents the development of a robotic assembly capable of carrying out the entire sequence of roof bolting operations in full and partial autonomous sensor-driven rock bolting operations to achieve a high-impact health and safety intervention for equipment operators. The automation of a complete cycle of drill steel positioning, drilling, bolt orientation and placement, resin placement, and bolt securing is discussed using an anthropomorphic robotic arm.A human-computer interface is developed to enable the interaction of the operators with the machines. Collision detection techniques will have to be implemented to minimize the impact after an unexpected collision has occurred. A robust failure-detection protocol is developed to check the vital parameters of robot operations continuously. This unique approach to automation of small materials handling is described with lessons learned. A user-centered GUI has been developed that allows for a human user to control and monitor the autonomous roof bolter. Preliminary tests have been conducted in a mock mine to evaluate the developed system\u27s performance. In addition, a number of different scenarios simulating typical missions that a roof bolter needs to undertake in an underground coal mine were tested

Automation and Robotics: Latest Achievements, Challenges and Prospects

This SI presents the latest achievements, challenges and prospects for drives, actuators, sensors, controls and robot navigation with reverse validation and applications in the field of industrial automation and robotics. Automation, supported by robotics, can effectively speed up and improve production. The industrialization of complex mechatronic components, especially robots, requires a large number of special processes already in the pre-production stage provided by modelling and simulation. This area of research from the very beginning includes drives, process technology, actuators, sensors, control systems and all connections in mechatronic systems. Automation and robotics form broad-spectrum areas of research, which are tightly interconnected. To reduce costs in the pre-production stage and to reduce production preparation time, it is necessary to solve complex tasks in the form of simulation with the use of standard software products and new technologies that allow, for example, machine vision and other imaging tools to examine new physical contexts, dependencies and connections

The Impact of Occupational Safety on Logistics and Automation in Industrial Plants

Research on workplace health and safety analyses the integration of work practices with safety, health and wealth of people at work. The aim of occupational safety is to realize a safe and health work environment, eliminating or reducing the risks for workers' safety and health. The objective of this thesis is the study, integration, development and application of innovative approaches and models for decision-making support in the context of occupational safety in industrial plants and logistics. Such methodologies are expected to lead practitioners and decision-makers, in particular safety professionals and companies, in the management of occupational safety. In particular, this research focuses on the integration and application of ergonomics principles to reduce biomechanical overload of manual work, and methodologies and solutions to improve safety of confined space work in industrial plants. The study of biomechanical overload due to manual handling of loads and awkward postures is the object of several researches and publications addressing the ergonomic risk assessment and the ergonomic approach to remove or reduce the risk of manual handling injuries and disorders. Furthermore, when awkward postures are assumed in high-risk workplaces as confined spaces, the overall risk of work is extremely high. Confined space work is a high-risk activity, posing a significant hazard for both workers and rescuers involved in the emergency response. The leading cause of accidents and fatalities in confined spaces is atmospheric condition (Sahli & Armstrong 1992, Harris et al. 2005, Flynn & Susi, 2010, Meeker, Susi & Flynn 2010, Ye 2011, Bellamy 2015). Further common causes are fire, explosion, ignition of flammable contaminants, spontaneous combustion and contact with temperature extremes. Besides, work activities in confined spaces (e.g., welding and maintenance tasks) frequently require awkward and static postures, at high temperatures. This thesis stresses the importance of implementing health and safety interventions at workplace. These interventions have impact not only on enterprise level but also on individual and social levels. Furthermore, protection of human life is a matter of human rights and human life has an invaluable value. In this thesis, the role of occupational safety and safety strategy as means for the improvement of workers and companies’ performances clearly emerges. Two parallel research fields on occupational safety are investigated: ergonomics and confined spaces. Selected data are introduced related to occupational accidents and diseases due to biomechanical overload and work in confined spaces. The literature survey on controls for risk elimination and reduction shows that technology for safety is available. Nevertheless, injuries and accidents still occur, i.e. safety is frequently considered an expensive investment and a compliance obligation. Specifically, administrative and engineering controls for risk elimination and reduction are introduced for each research field. Administrative controls include work procedures and mathematical models for the design of safe work processes. Such control methods reduce the workers' exposure to occupational risk factors. The ergonomic analysis of manual handling activities drives the modelling by multi-objective optimisation problems in the design of administrative controls for the ergonomic risk reduction in different industries. Administrative controls for risks in confined spaces include work procedures, a multi-criteria decision tool and the analysis of the requirements of Internet of Things (IOT) technologies for reducing the risk of confined space work. The introduction of automation to replace manual work and engineering controls for confined space work are analysed for the risk elimination. Results show that the integration of ergonomics and safety principles in the industrial processes plays a leading role in the successful implementation of the overall strategy. Technologies for safe confined space work and technical solutions assisting workers during manual material handling tasks have been the focus of the Solutions Database Project, funded by the Azienda Unità Sanitaria Locale of Bologna (AUSL), Italy. The study of such technological and technical solutions lead to the development of the Solutions Database, a free access database available online for researchers and practitioners (http://safetyengineering.din.unibo.it/en/banca-delle-soluzioni). The thesis ends with the recommendation that companies should integrate workplace health and safety principles to human resource management and work organisation. The management of health and safety issues should be considered to be crucial for workplace development, as a lever to increase performance and productivity. Finally, this research aims to support and reinforce the evolution of the concept of safety in industry, from ex post required obligation, to ex ante optimisation strategy

Soft Gloves: A Review on Recent Developments in Actuation, Sensing, Control and Applications

Interest in soft gloves, both robotic and haptic, has enormously grown over the past decade, due to their inherent compliance, which makes them particularly suitable for direct interaction with the human hand. Robotic soft gloves have been developed for hand rehabilitation, for ADLs assistance, or sometimes for both. Haptic soft gloves may be applied in virtual reality (VR) applications or to give sensory feedback in combination with prostheses or to control robots. This paper presents an updated review of the state of the art of soft gloves, with a particular focus on actuation, sensing, and control, combined with a detailed analysis of the devices according to their application field. The review is organized on two levels: a prospective review allows the highlighting of the main trends in soft gloves development and applications, and an analytical review performs an in-depth analysis of the technical solutions developed and implemented in the revised scientific research. Additional minor evaluations integrate the analysis, such as a synthetic investigation of the main results in the clinical studies and trials referred in literature which involve soft gloves

A Helping Hand for Europe: The Competitive Outlook for the EU Robotics Industry

This report is one of a series resulting from a project entitled ¿Competitiveness by Leveraging Emerging Technologies Economically¿ (COMPLETE), carried out by JRC-IPTS. Each of the COMPLETE studies illustrates in its own right that European companies are active on many fronts of emerging and disruptive ICT technologies and are supplying the market with relevant products and services. Nevertheless, the studies also show that the creation and growth of high tech companies is still very complex and difficult in Europe, and too many economic opportunities seem to escape European initiatives and ownership. COMPLETE helps to illustrate some of the difficulties experienced in different segments of the ICT industry and by growing potential global players. Hopefully, COMPLETE will contribute to a better understanding of the opportunities and help shape better market conditions (financial, labour and product markets) to sustain European competitiveness and economic growth. This report deals with robotics applications in general, and in two specific areas selected because of potential market and EU capability in these areas: robotics applications in SMEs, and robotics safety. It starts by introducing the state of the art in robotics, their applications, market size, value chains and disruptive potential of emerging robotics technologies. For each of the two specific areas, the report describes the EU landscape, potential market, benefits, difficulties, and how these might be overcome. The last chapter draws together the findings of the study, to consider EU competitiveness in robotics, opportunities and policy implications. The work is based on desk research and targeted interviews with industry experts in Europe and beyond. The results were reviewed by experts and in a dedicated workshop.JRC.DDG.J.4-Information Societ
