With the development of virtual reality technology, 3D virtual robots are increasingly used in primary school robot programming teaching. Therefore, in this study, 64 fifth-grade students were divided into two groups, and the experimental research method was used to investigate which method is more conducive to improving students' learning engagement and computational thinking by combining or separately using 3D virtual robots and physical robots in robot programming courses. The results show that the combined use of 3D virtual and physical robots in a robot programming course improves students' programming self-efficacy scale and learning engagement, thus improving students' computational thinking.

This paper examines whether the robot's face-turning behavior toward humans during handover can be a behavior cue that supports the human action plan in accomplishing a task. A series of behavior cues observed in interactions, such as Joint action, are understood as social signals, which can be used as cues to help each other make decisions about their own action plans. We hope that constructing a inference model of empathetic behavior will enable humans and robots to share the intention of their behavioral goals in joint action. We conducted temporal analysis and subjective evaluation of the receiver's behavior in an object handover experiment. The results showed that the subjective experience did not significantly change when the robot turned its head toward the receiver, but the time to receive the participant significantly increased. This suggests that the robot's face-turning behavior may have altered the receiver's human prediction and action plan, causing the receiver to hesitate to respond. This shows the potential for the robot face-turning to a human which could change the human inference and response behavior plan.

A graphical programming tool is developed in a view to help beginners realize the importance of coding in the form of physical robotic movement. Introducing a programming language to students with no background is often felt to be challenging in terms of syntax and control flow of a language. The paper discusses an open source graphical programming tool built on Minibloq platform that allows students to focus more on creative part of programming. The paper proposes a graphical approach to programming where a student need not remember any constructs of a programming language, but relies on the approach to solve a problem. The programming utility is developed for an open source Arduino platform. Currently the tool is developed to control a real robot built around Arduino platform. Thus a platform to learn fundamentals of programming as well as robotics is made available to students. The graphical programming tool with the robotic hardware was found to be easy to learn by high school students during an outreach program conducted by the authors. The framework is also extendable beyond programming and can be further developed to understand robotics.

This article presents a map of studies on the educational potential of robotics and programming in inclusive settings. The scoping review methodology was used based on the procedures recommended by the Joanna Briggs Institute. This method was chosen because of the need to examine and map the main trends in the work done with robotics and programming in educational contexts for children with special needs. Our concern was to search for emerging scientific evidence on the educational potential of robotics and programming in inclusive contexts. Searches were conducted in the Scopus, Web of Science, and Eric databases between 2015 and 2022. The analysis identified five research papers that met the inclusion and exclusion criteria. The results show little abundance of studies in this area, which justifies the scoping methodology. The selected studies show a prevalent trend toward the inclusion of educational robotics and not so much programming. They reveal that the use of robotics and/or programming is a pedagogical strategy that promotes greater interaction, participation, and motivation in children, as well as greater socialization. The relevance of the theme and its complexity highlight the need for further research on this subject. © 2023 IEEE.

This paper introduces Switch mode, a design strategy to introduce a middle ground to support learners in transitioning from block-based to text-based programming. The Switch mode strategy allows learners to author text-based commands inside a block-based programs. Switch mode blocks can be added by directly dragging and dropping Switch mode blocks from the blocks pallet to the program canvas (Figure 1a) or by right clicking a conventional block and selecting the convert option (Figure 1b). In embedding a scaffolded way to introduce text-based programming in a blocks-based environment, Switch mode can meet the user at their current level of ability in blocks, while also help them move to more sophisticated and powerful programming languages. In providing a means for learns to tinker with text-based programming while still having the supports of block-based tools, Switch mode contributes a novel addition to the growing ecosystem of tools designed to transit novices to the practice of text-based programming. © 2023 Copyright held by the owner/author(s).

In missions for a set of autonomous vehicles given a complex environment with obstacles and many waypoints to visit, risk-aware routing plays an important role. In this paper, we consider multi-robot, multi-goal motion planning where unsafe areas should be avoided. We assume a geometric environment for a set of high-dimensional robots, providing a motion model with nonlinear dynamics that, for a given state and a small time step, applies a control action and provides a next state or reports a collision. As there are anonymous goals meaning there is no predefined assignment of goals to the robots, the approach assigns goals to them on-the-fly during the solution process. We study the computational limits and possibilities of our approach, derive a scaling framework system that plans and executes the safe travel for the given fleet of robots, and we conduct experiments for benchmark scenarios.

The rise of automation has provided an opportunity to achieve higher efficiency in manufacturing processes, yet it often compromises the flexibility required to promptly respond to evolving market needs and meet the demand for customization. Human-robot collaboration attempts to tackle these challenges by combining the strength and precision of machines with human ingenuity and perceptual understanding. In this paper, we conceptualize and propose an implementation framework for an autonomous, machine learning-based manipulator that incorporates human-in-the-loop principles and leverages Extended Reality (XR) to facilitate intuitive communication and programming between humans and robots. Furthermore, the conceptual framework foresees human involvement directly in the robot learning process, resulting in higher adaptability and task generalization. The paper highlights key technologies enabling the proposed framework, emphasizing the importance of developing the digital ecosystem as a whole. Additionally, we review the existent implementation approaches of XR in human-robot collaboration, showcasing diverse perspectives and methodologies. The challenges and future outlooks are discussed, delving into the major obstacles and potential research avenues of XR for more natural human-robot interaction and integration in the industrial landscape.

2024 International Conference on Intelligent robots and Systems

Large language models (LLMs) exhibit a wide range of promising capabilities - from step-by-step planning to commonsense reasoning -that provide utility for robot navigation. However, as humans communicate with robots in the real world, ambiguity and uncertainty may be embedded inside spoken instructions. While LLMs are proficient at processing text in human conversations, they often encounter difficulties with the nuances of verbal instructions and, thus, remain prone to hallucinate trust in human command. In this work, we present TrustNavGPT, an LLM-based audio-guided navigation agent that uses affective cues in spoken communication-elements such as tone and inflection that convey meaning beyond words-allowing it to assess the trustworthiness of human commands and make effective, safe decisions. Experiments across a variety of simulation and real-world setups show a 70.46% success rate in catching command uncertainty and an 80% success rate in finding the target, 48.30%, and 55% outperform existing LLM-based navigation methods, respectively. Additionally, TrustNavGPT shows remarkable resilience against adversarial attacks, highlighted by a 22%+ less decrease ratio than the existing LLM navigation method in success rate. Our approach provides a lightweight yet effective approach that extends existing LLMs to model audio vocal features embedded in the voice command and model uncertainty for safe robotic navigation.

Online Damage Recovery for Physical robots with Hierarchical Quality-Diversity

引用

ACM Transactions on Evolutionary Learning and Optimization 2023年第2期3卷 1-23页

In real-world environments, robots need to be resilient to damages and robust to unforeseen scenarios. Quality-Diversity (QD) algorithms have been successfully used to make robots adapt to damages in seconds by leveraging a diverse set of learned skills. A high diversity of skills increases the chances of a robot to succeed at overcoming new situations since there are more potential alternatives to solve a new task. However, finding and storing a large behavioural diversity of multiple skills often leads to an increase in computational complexity. Furthermore, robot planning in a large skill space is an additional challenge that arises with an increased number of skills. Hierarchical structures can help to reduce this search and storage complexity by breaking down skills into primitive skills. In this article, we extend the analysis of the Hierarchical Trial and Error algorithm, which uses a hierarchical behavioural repertoire to learn diverse skills and leverages them to make the robot adapt quickly in the physical world. We show that the hierarchical decomposition of skills enables the robot to learn more complex behaviours while keeping the learning of the repertoire tractable. Experiments with a hexapod robot both in simulation and the physical world show that our method solves a maze navigation task with up to, respectively, 20% and 43% less actions than the best baselines while having 78% less complete failures. © 2023 Copyright held by the owner/author(s).
