    A gentle transition from Java programming to Web Services using XML-RPC

    Get PDF
    Exposing students to leading edge vocational areas of relevance such as Web Services can be difficult. We show a lightweight approach by embedding a key component of Web Services within a Level 3 BSc module in Distributed Computing. We present a ready to use collection of lecture slides and student activities based on XML-RPC. In addition we show that this material addresses the central topics in the context of web services as identified by Draganova (2003)

    Teaching humanoid robotics by means of human teleoperation through RGB-D sensors

    Get PDF
    This paper presents a graduate course project on humanoid robotics offered by the University of Padova. The target is to safely lift an object by teleoperating a small humanoid. Students have to map human limbs into robot joints, guarantee the robot stability during the motion, and teleoperate the robot to perform the correct movement. We introduce the following innovative aspects with respect to classical robotic classes: i) the use of humanoid robots as teaching tools; ii) the simplification of the stable locomotion problem by exploiting the potential of teleoperation; iii) the adoption of a Project-Based Learning constructivist approach as teaching methodology. The learning objectives of both course and project are introduced and compared with the students\u2019 background. Design and constraints students have to deal with are reported, together with the amount of time they and their instructors dedicated to solve tasks. A set of evaluation results are provided in order to validate the authors\u2019 purpose, including the students\u2019 personal feedback. A discussion about possible future improvements is reported, hoping to encourage further spread of educational robotics in schools at all levels

    Robot trajectory planning using OLP and structured light 3D machine vision

    Get PDF
    This paper proposes a new methodology for robotic offline programming (OLP) addressing the issue of automatic program generation directly from 3D CAD models and verification through online 3D reconstruction. Limitations of current OLP include manufacturing tolerances between CAD and workpieces and inaccuracies in workpiece placement and modelled work cell. These issues are addressed and demonstrated through surface scanning, registration, and global and local error estimation. The method allows the robot to adjust the welding path designed from the CAD model to the actual workpiece. Alternatively, for non-repetitive tasks and where a CAD model is not available, it is possible to interactively define the path online over the scanned surface

    Do Robots Dream of Virtual Sheep: Rediscovering the "Karel the Robot" Paradigm for the "Plug&Play Generation"

    Get PDF
    We introduce ”C-Sheep”, an educational system designed to teach students the fundamentals of computer programming in a novel and exciting way. Recent studies suggest that computer science education is fast approaching a crisis - application numbers for degree courses in the area of computer programming are down, and potential candidates are put off the subject which they do not fully understand. We address this problem with our system by providing the visually rich virtual environment of ”The Meadow”, where the user writes programs to control the behaviour of a sheep using our ”CSheep” programming language. This combination of the ”Karel the Robot” paradigm with modern 3D computer graphics techniques, more commonly found in computer games, aims to help students to realise that computer programming can be an enjoyable and rewarding experience and intends to help educators with the teaching of computer science fundamentals. Our mini-language-like system for computer science education uses a state of the art rendering engine offering features more commonly found in entertainment systems. The scope of the mini-language is designed to fit in with the curriculum for the first term of an introductory computer program ming course (using the C programming language)

    Integrating mobile robotics and vision with undergraduate computer science

    Get PDF
    This paper describes the integration of robotics education into an undergraduate Computer Science curriculum. The proposed approach delivers mobile robotics as well as covering the closely related field of Computer Vision, and is directly linked to the research conducted at the authors’ institution. The paper describes the most relevant details of the module content and assessment strategy, paying particular attention to the practical sessions using Rovio mobile robots. The specific choices are discussed that were made with regard to the mobile platform, software libraries and lab environment. The paper also presents a detailed qualitative and quantitative analysis of student results, including the correlation between student engagement and performance, and discusses the outcomes of this experience
