    Abstract: In this paper, a distributed adaptive partitioning algorithm inspired by division of labor in honeybees is investigated for its applicability in a swarm of underwater robots in one hand and is qualitatively compared with the behavior of honeybee colonies on the other hand. The algorithm, partitioning social inhibition (PSI), is based on local interactions and uses a simple logic inspired from age-polyethism and task allocation in honeybee colonies. The algorithm is analyzed in simulation and is successfully applied here to partition a swarm of underwater robots into groups demonstrating its adaptivity to changes and applicability in real world systems. In a turn towards the inspiration origins of the algorithm, three honeybee colonies are then studied for age-polyethism behaviors and the results are contrasted with a simulated swarm running the PSI algorithm. Similar effects are detected in both the biological and simulated swarms suggesting biological plausibility of the mechanisms employed by the artificial system.

    Abstract: UNLABELLED In this research work, we present a Multimodal Guidance System (MGS) whose aim is to provide dynamic assistance to persons with disabilities (PWD) while performing manual activities such as drawing, coloring in and foam-cutting tasks. The MGS provides robotic assistance in the execution of 2D tasks through haptic and sound interactions. Haptic technology provides the virtual path of 2D shapes through the point-based approach, while sound technology provides audio feedback inputs related to the hand's velocity while sketching and filling or cutting operations. By combining this Multimodal System with the haptic assistance, we have created a new approach with possible applications to such diverse fields as physical rehabilitation, scientific investigation of sensorimotor learning and assessment of hand movements in PWD. The MGS has been tested by people with specific disorders affecting coordination, such as Down syndrome and developmental disabilities, under the supervision of their teachers and care assistants inside their learning environment. A Graphic User Interface has been designed for teachers and care assistants in order to provide training during the test sessions. Our results provide conclusive evidence that the effect of using the MGS increases the accuracy in the tasks operations. IMPLICATIONS FOR REHABILITATION The Multimodal Guidance System (MGS) is an interface that offers haptic and sound feedback while performing manual tasks. Several studies demonstrated that the haptic guidance systems can help people in recovering cognitive function at different levels of complexity and impairment. The applications supported by our device could also have an important role in supporting physical therapist and cognitive psychologist in helping patients to recover motor and visuo-spatial abilities.

    Abstract: This paper provides the results of three focus groups organized in the framework of the ROBADOM project, aiming at designing a service type assistive robot for the elderly with mild cognitive impairment living at home. The main objective of these focus groups was to give some recommendations to engineers in charge of the design of the robot’s appearance. Results showed that although many humanoid robots were criticized by most participants, some small creative humanoid robots were appreciated. However, beyond the issue of the robot appearance, many ethical and social issues were raised. These focus groups offered an opportunity for participants to discuss the very idea of an assistive robot and to challenge some implicit preconceptions of the roboticists. Finally, we discuss how assistive robots could be designed considering the social context of the elderly and how to implicate the elderly as future end-users in the design process.

    Abstract: This paper aims to show the effectiveness of a (inter / multi)disciplinary team, based on the technology developers, elderly care organizations, and designers, in developing the ASTRO robotic system for domiciliary assistance to elderly people. The main issues presented in this work concern the improvement of robot's behavior by means of a smart sensor network able to share information with the robot for localization and navigation, and the design of the robot's appearance and functionalities by means of a substantial analysis of users' requirements and attitude to robotic technology to improve acceptability and usability.
