Available online at: https://doi.org/10.1007/s12369-019-00607-xThis paper presents a contribution to the active field of robotics research with the aim of supporting the development of social and collaborative skills of children with Autism Spectrum Disorders (ASD). We present a novel experiment where the classical roles are reversed: in this scenario the children are the teachers providing positive or negative reinforcement to the Kaspar robot in order for the robot to learn arbitrary associations between different toy names and the locations where they are positioned. The objective of this work is to develop games which help children with ASD develop collaborative skills and also provide them tangible example to understand that sometimes learning requires several repetitions. To facilitate this game we developed a reinforcement learning algorithm enabling Kaspar to verbally convey its level of uncertainty during the learning process, so as to better inform the children interacting with Kaspar the reasons behind the successes and failures made by the robot. Overall, 30 Typically Developing (TD) children aged between 7 and 8 (19 girls, 11 boys) and 6 children with ASD performed 22 sessions (16 for TD; 6 for ASD) of the experiment in groups, and managed to teach Kaspar all associations in 2 to 7 trials. During the course of study Kaspar only made rare unexpected associations (2 perseverative errors and 1 win-shift, within a total of 272 trials), primarily due to exploratory choices, and eventually reached minimal uncertainty. Thus the robot's behavior was clear and consistent for the children, who all expressed enthusiasm in the experiment.Peer reviewe

Greeny: NAO As Assistive Teaching Tool For Recycling in Early Childhood Education

Greeny is proposed as an assistive teaching tool for early childhood education to improve on the learning experience of the students, as well as facilitating the teaching and learning process for young children (from the age of 3 to 5 years old, or pre-school students) on the importance of saving the Mother Nature through recycling items. The undertaking of this approach is motivated by the interest of improving the teaching and learning experience in early childhood education, as well as improving the awareness of recycling and sustaining the environment. The approach will utilize the commercially available robot, which is NAO. Greeny will demonstrate to the young children on sorting recycle items into the right container and explaining the significance of recycling. Surveys are conducted as preliminary investigation to assess the recycling awareness in the public. An interactive module for the Greeny is to be developed and implemented to assist the teacher in teaching and learning process. Iterative development model is being used as the methodology for development. At the end of the development, testing will be done onto the prototype before being implemented for the teaching and learning. After completion of prototype testing, testing on young children will be done by evaluating the success and failure of sorting the recycle items into the right bin to assess on the grasp of understanding on the input gain from the teaching and learning with intervention of robot as assistive teaching tool

Social robots in educational contexts: developing an application in enactive didactics

Due to advancements in sensor and actuator technology robots are becoming more and more common in everyday life. Many of the areas in which they are introduced demand close physical and social contact. In the last ten years the use of robots has also increasingly spread to the field of didactics, starting with their use as tools in STEM education. With the advancement of social robotics, the use of robots in didactics has been extended also to tutoring situations in which these \u201csocially aware\u201d robots interact with mainly children in, for example, language learning classes. In this paper we will give a brief overview of how robots have been used in this kind of settings until now. As a result it will become transparent that the majority of applications are not grounded in didactic theory. Recognizing this shortcoming, we propose a theory driven approach to the use of educational robots, centred on the idea that the combination of enactive didactics and social robotics holds great promises for a variety of tutoring activities in educational contexts. After defining our \u201cEnactive Robot Assisted Didactics\u201d approach, we will give an outlook on how the use of humanoid robots can advance it. On this basis, at the end of the paper, we will describe a concrete, currently on-going implementation of this approach, which we are realizing with the use of Softbank Robotics\u2019 Pepper robot during university lectures

Social robots to support practitioners in the education and clinical care of children: The CARER-AID project

The Controlled Autonomous Robot for Early detection and Rehabilitation of Autism and Intellectual Disability (CARER-AID) project aimed at verifying the effects of the introduction of a humanoid robot in the clinical routine as a supervised autonomous assistant to support clinical staff in the care of individuals with Autism Spectrum Disorder (ASD) associated with Intellectual Disability (ID). The CARER-AID project was undertaken by a multidisciplinary team composed of experts in artificial intelligence and robotics and clinical psychologists experienced in the treatment of ID. The literature shows that children with ASD seem to prefer robotic devices over non-robotic instruments and indeed humans. Starting from this, CARER-AID clinical studies provided experimental evidence that demonstrated several potential benefits of robot-assisted therapy when treating children with neurodevelopmental disorders, such as ASD with or without ID. Alongside the study in a clinical setting, the project also investigated the acceptability and the attitudes towards social robotics in an educational context. The study evaluated the teachers' perception of introducing a humanoid robot in a kindergarten and the attitudes of children with Typical Development (TD) towards. The results of the clinical and educational studies showed the usefulness of social robotics in supporting practitioners in their interventions with both TD and neurodevelopmental disorders. The CARER-AID project offers a unitary vision of a robot that can serve in different aspects and levels of the care, from the education to the therapeutic rehabilitation, from assessment to monitoring of results, providing assistance to caregivers and professionals at school and in clinical settings

A Pilot Study with a Novel Setup for Collaborative Play of the Humanoid Robot KASPAR with children with autism

This article is distributed under the terms of the Creative Commons Attribution License which permits any use, distribution, and reproduction in any medium, provided the original author(s) and the source are credited.This article describes a pilot study in which a novel experimental setup, involving an autonomous humanoid robot, KASPAR, participating in a collaborative, dyadic video game, was implemented and tested with children with autism, all of whom had impairments in playing socially and communicating with others. The children alternated between playing the collaborative video game with a neurotypical adult and playing the same game with the humanoid robot, being exposed to each condition twice. The equipment and experimental setup were designed to observe whether the children would engage in more collaborative behaviours while playing the video game and interacting with the adult than performing the same activities with the humanoid robot. The article describes the development of the experimental setup and its first evaluation in a small-scale exploratory pilot study. The purpose of the study was to gain experience with the operational limits of the robot as well as the dyadic video game, to determine what changes should be made to the systems, and to gain experience with analyzing the data from this study in order to conduct a more extensive evaluation in the future. Based on our observations of the childrens’ experiences in playing the cooperative game, we determined that while the children enjoyed both playing the game and interacting with the robot, the game should be made simpler to play as well as more explicitly collaborative in its mechanics. Also, the robot should be more explicit in its speech as well as more structured in its interactions. Results show that the children found the activity to be more entertaining, appeared more engaged in playing, and displayed better collaborative behaviours with their partners (For the purposes of this article, ‘partner’ refers to the human/robotic agent which interacts with the children with autism. We are not using the term’s other meanings that refer to specific relationships or emotional involvement between two individuals.) in the second sessions of playing with human adults than during their first sessions. One way of explaining these findings is that the children’s intermediary play session with the humanoid robot impacted their subsequent play session with the human adult. However, another longer and more thorough study would have to be conducted in order to better re-interpret these findings. Furthermore, although the children with autism were more interested in and entertained by the robotic partner, the children showed more examples of collaborative play and cooperation while playing with the human adult.Peer reviewe
