ROBOSIM: An intelligent simulator for robotic systems

The purpose of this paper is to present an update of an intelligent robotics simulator package, ROBOSIM, first introduced at Technology 2000 in 1990. ROBOSIM is used for three-dimensional geometrical modeling of robot manipulators and various objects in their workspace, and for the simulation of action sequences performed by the manipulators. Geometric modeling of robot manipulators has an expanding area of interest because it can aid the design and usage of robots in a number of ways, including: design and testing of manipulators, robot action planning, on-line control of robot manipulators, telerobotic user interface, and training and education. NASA developed ROBOSIM between 1985-88 to facilitate the development of robotics, and used the package to develop robotics for welding, coating, and space operations. ROBOSIM has been further developed for academic use by its co-developer Vanderbilt University, and has been in both classroom and laboratory environments for teaching complex robotic concepts. Plans are being formulated to make ROBOSIM available to all U.S. engineering/engineering technology schools (over three hundred total with an estimated 10,000+ users per year)

An approach based on VR to design industrial human-robot collaborative workstations

This paper presents an integrated approach for the design of human-robot collaborative workstations in industrial shop floors. In particular, the paper presents how to use virtual reality (VR) technologies to support designers in the creation of interactive workstation prototypes and in early validation of design outcomes. VR allows designers to consider and evaluate in advance the overall user experience, adopting a user-centered perspective. The proposed approach relies on two levels: the first allows designers to have an automatic generation and organization of the workstation physical layout in VR, starting from a conceptual description of its functionalities and required tools; the second aims at supporting designers during the design of human-machine interfaces (HMIs) by interaction mapping, HMI prototyping and testing in VR. The proposed approach has been applied on two realistic industrial case studies related to the design of an intensive warehouse and a collaborative assembly workstation for automotive industry, respectively. The two case studies demonstrate how the approach is suited for early prototyping of complex environments and human-machine interactions by taking into account the user experience from the early phases of design

MASHUP FOR INTERNSHIP PLACEMENT (MlP)

Mashup, a web application that integrates data from multiple data sources or APis to provide unique services. In this project Mashup for Internship Placement (MIP), involves solving multiple problems such as extracting data from multiple sources, cleaning it, and integrate it together. In the case study presented in this paper, Mashup has been applied as one of the pattern for knowledge sharing. The problem statement for this research paper is there is difficulties for student to decide which internship offer to accept because they lack of knowledge about the company and the job description. The objective of the research are to investigate Mashup pattern for knowledge sharing system and to develop a prototype system that incorporate features that allow user to view the location and information about the company which offer the internship placement. The methodology used to create Mashup system is Prototyping based methodology and Yahoo Pipes as the platform. Data from Google Maps is extract using Fetch Feed widget in Yahoo Pipes and integrate the feeds with Yahoo Pipes to show result on interactive map rather than traditional list. MIP contains information about company that offers internship placement with the location view on the map. This Mashup also can help student to be focus on the decision making for their internship placement as they may get all information gathered in one application

Interactive formal specification for efficient preparation of intelligent automation systems

The automation system of the future will consist of an increasing amount of complex resources, such as collaborative robots and/or autonomously roaming robots for material handling. To control these devices in an environment shared with human operators require state of the art computer perception and motion planning algorithms to be used as part of the automation system. This new type of intelligent automation system, where intelligent machines and learning algorithms are replacing more traditional automation solutions, requires new methods and workflows to keep up with the increase in complexity. This paper presents an interactive and iterative framework for solving some of these new challenges. The framework supports model-based control system preparation performed simultaneously to preparation of 3D geometries, positioning of robots, and tool design. The workflow enables an interactive preparation process, where new resources and constraints can be added to a live (real or simulated) automation system and control system failures can be analyzed in familiar tools for virtual preparation. Additionally, the paper describes how the integrated preparation process was applied to reconfiguring an industrial use case that includes a collaborative robot working side by side with a human operator, smart tools, and a vision system for localizing both work objects and tools

Working Notes from the 1992 AAAI Workshop on Automating Software Design. Theme: Domain Specific Software Design

The goal of this workshop is to identify different architectural approaches to building domain-specific software design systems and to explore issues unique to domain-specific (vs. general-purpose) software design. Some general issues that cut across the particular software design domain include: (1) knowledge representation, acquisition, and maintenance; (2) specialized software design techniques; and (3) user interaction and user interface

An intelligent Geographic Information System for design

Recent advances in geographic information systems (GIS) and artificial intelligence (AI) techniques have been summarised, concentrating on the theoretical aspects of their construction and use. Existing projects combining AI and GIS have also been discussed, with attention paid to the interfacing methods used and problems uncovered by the approaches. AI and GIS have been combined in this research to create an intelligent GIS for design. This has been applied to off-shore pipeline route design. The system was tested using data from a real pipeline design project. [Continues.

The potential of Quality Function Deployment (QFD) in reducing work-related musculoskeletal disorders

Musculoskeletal disorders (MSDs) frequently affect the health and well-being of workers and can hinder growth in the industrial sector. Research indicates that user requirements to reduce workplace risk factors for MSDs are not always effectively conveyed to practitioners of design. This creates a mismatch between these requirements and what is ultimately produced. Quality function deployment (QFD) is a structured collaborative design approach, widely used in industry. The aim of this research was to explore the potential of a QFD-based design tool to enhance such communication in the design process and help reduce work-related MSDs. In order to evaluate user knowledge and ability to identify workplace risks and the subsequent requirements for design, a multi-methods study was undertaken with cleaners (n= 10), joiners (n= 6) and plumbers (n= 6) and their line managers (n= 6). Methods included semi-structured interviews, task analysis, REBA and body part discomfort maps. The findings revealed that these workers were in general able to identify risks to their musculoskeletal health and make design suggestions related to specific tasks. All of the workers expressed concern about manual handling, and issues related to awkward postures were also identified by the majority. A QFD-based design tool (with guidance material) was then developed to facilitate communication in the design process. It consisted of six features to encompass the design process, and included tools and techniques with supplementary templates to aid practitioners. In order to evaluate its feasibility with respect to current practice, an online questionnaire survey was conducted with a cohort of practitioners of ergonomics and design (n= 32). Of these, the majority rated highly the importance of an integrated approach for participatory design to help reduce work-related MSDs. They also suggested elements to be included in the design tool, which were in congruence with the features already included. To evaluate the strengths and weaknesses of the design tool in the field setting, in-depth interviews using a walkthrough approach (n= 8) and case studies of specific work tasks (n= 3) were conducted with practitioners. The findings showed that the design tool would be very useful in managing and presenting design information. In particular, practitioners liked being provided with design principles to help systematically identify design solutions to reduce risks and using the QFD-based matrices to present such information. Limitations of the tool were identified as inadequacy of guidance, the lack of automated procedures and the time required to set up and learn. The design tool (and guidance material) seems to have potential in facilitating the sharing of design information among the stakeholders of the design process
