摘要： A telescopic miniature in-pipe robot based on the continuous cam drive, crutch of the tensioning mechanism and ratchet self-locking to realize creep is developed in this paper, which features high tractive force and payload capacity, adapting to pipe diameter or roundness variations. It is suitable for locomotion and inspection in the inner small-diameter pipelines. Firstly, the conceptual design of this miniature robot is proposed, and its relevant locomotion principle is introduced in detail. Then the dynamic model based on spatial operator algebra is built to deduce the driving force. Secondly, to prove its feasibility and running conditions, the virtual prototype simulation is carried out for the robot based on the results obtained above. Thirdly, the miniature pipe robot is simulated in straight and bends by using the automatic dynamic analysis of mechanical systems (ADAMS) to understand its kinematic and dynamic behaviour. Finally, the results show that the telescopic miniature in-pipe robot walking mechanism is efficient, stable and easy to control.

摘要： This paper describes insights gained from a decade of autonomous marine systems development at the University of Sydney's Australian Centre for Marine Robotics. Over the course of this time, we have deployed numerous vehicles and imaging platforms in support of applications in engineering science, marine ecology, archaeology and geoscience. We have operated an Australia-wide benthic observing program designed to deliver precisely navigated, repeat imagery of the seafloor. This initiative makes extensive use of Autonomous Underwater Vehicles (AUVs) to collect high-resolution stereo imagery, multibeam sonar and water column measurements on an annual or semi-annual basis at sites around Australia, spanning the full latitudinal range of the continent from tropical reefs in the north to temperate regions in the south. We have also contributed to expeditions to document coral bleaching, cyclone recovery, submerged neolithic settlement sites, ancient shipwrecks, methane seeps and deepwater hydrothermal vents. We briefly consider how automated tools for working with this imagery have facilitated the resulting science outcomes.

摘要： Humans can learn a language through physical interaction with their environment and semiotic communication with other people. It is very important to obtain a computational understanding of how humans can form symbol systems and obtain semiotic skills through their autonomous mental development. Recently, many studies have been conducted regarding the construction of robotic systems and machine learning methods that can learn a language through embodied multimodal interaction with their environment and other systems. Understanding human?-social interactions and developing a robot that can smoothly communicate with human users in the long term require an understanding of the dynamics of symbol systems. The embodied cognition and social interaction of participants gradually alter a symbol system in a constructive manner. In this paper, we introduce a field of research called symbol emergence in robotics (SER). SER represents a constructive approach towards a symbol emergence system. The symbol emergence system is socially self-organized through both semiotic communications and physical interactions with autonomous cognitive developmental agents, i.e. humans and developmental robots. In this paper, specifically, we describe some state-of-art research topics concerning SER, such as multimodal categorization, word discovery, and double articulation analysis. They enable robots to discover words and their embodied meanings from raw sensory-motor information, including visual information, haptic information, auditory information, and acoustic speech signals, in a totally unsupervised manner. Finally, we suggest future directions for research in SER.

关键词： Educational robotics   Teacher preparation   Engagement   STEM education   Elementary education  

摘要： We report a research project with a purpose of helping teachers learn how to design and implement science, technology, engineering, and mathematics (STEM) lessons using robotics. Specifically, pre-service teachers' STEM engagement, learning, and teaching via robotics were investigated in an elementary teacher preparation course. Data were collected from surveys, classroom observations, interviews, and lesson plans. Both quantitative and qualitative data analyses indicated that pre-service teachers engaged in robotics activities actively and mindfully. Their STEM engagement improved overall. Their emotional engagement (e.g., interest, enjoyment) in STEM significantly improved and in turn influenced their behavioral and cognitive engagement in STEM. Their lesson designs showed their STEM teaching was developing in productive directions although further work was needed. These findings suggest that robotics can be used as a technology in activities designed to enhance teachers' STEM engagement and teaching through improved attitudes toward STEM. Future research and teacher education recommendations are also presented. (C) 2015 Elsevier Ltd. All rights reserved.
