Suitable task allocation in intelligent systems for assistive environments

The growing need of technological assistance to provide support to people with special needs demands for systems more and more efficient and with better performances. With this aim, this work tries to advance in a multirobot platform that allows the coordinated control of different agents and other elements in the environment to achieve an autonomous behavior based on the user’s needs or will. Therefore, this environment is structured according to the potentiality of each agent and elements of this environment and of the dynamic context, to generate the adequate actuation plans and the coordination of their execution.Peer ReviewedPostprint (author's final draft

Overview of some Command Modes for Human-Robot Interaction Systems

Interaction and command modes as well as their combination are essential features of modern and futuristic robotic systems interacting with human beings in various dynamical environments. This paper presents a synthetic overview concerning the most command modes used in Human-Robot Interaction Systems (HRIS). It includes the first historical command modes which are namely tele-manipulation, off-line robot programming, and traditional elementary teaching by demonstration. It then introduces the most recent command modes which have been fostered later on by the use of artificial intelligence techniques implemented on more powerful computers. In this context, we will consider specifically the following modes: interactive programming based on the graphical-user-interfaces, voice-based, pointing-on-image-based, gesture-based, and finally brain-based commands.info:eu-repo/semantics/publishedVersio

Telerounding: A Scoping Review and Implications for Future Healthcare Practice

Telerounding is slated to become an important avenue for future healthcare practice. As utilization of telerounding is increasing, a review of the literature is necessary to distill themes and identify critical considerations for the implementation of telerounding. We provide evidence of the utility of telerounding and considerations to support its implementation in future healthcare practice based on a scoping review. Method: We collected articles from nine scientific databases from the earliest dated available articles to August 2020. We identified whether each article centered on telerounding policies, regulations, or practice. We also organized information from each article and sorted themes into four categories: sample characteristics, technology utilized, study constructs, and research outcomes. Results: We identified 21 articles related to telerounding that fit our criteria. All articles emphasized telerounding practice. Most articles reported data collected from surgical wards, had adult samples, and utilized robotic telerounding systems. Most articles reported null effects or positive effects on their measured variables. Discussion: Providers and patients can benefit from the effective implementation of telerounding. Telerounding can support patient care by reducing travel expenses and opportunities for infection. Evidence suggests that telerounding can reduce patient length of stay. Patients and providers are willing to utilize telerounding, but patient willingness is influenced by age and education. Telerounding does not appear to negatively impact satisfaction or patient care. Organizations seeking to implement telerounding systems must consider education for their providers, logistics associated with hardware and software, scheduling, and characteristics of the organizational context that can support telerounding. Considerations provided in this article can mitigate difficulties associated with the implementation of telerounding

Development of a cognitive robotic system for simple surgical tasks

The introduction of robotic surgery within the operating rooms has significantly improved the quality of many surgical procedures. Recently, the research on medical robotic systems focused on increasing the level of autonomy in order to give them the possibility to carry out simple surgical actions autonomously. This paper reports on the development of technologies for introducing automation within the surgical workflow. The results have been obtained during the ongoing FP7 European funded project Intelligent Surgical Robotics (I-SUR). The main goal of the project is to demonstrate that autonomous robotic surgical systems can carry out simple surgical tasks effectively and without major intervention by surgeons. To fulfil this goal, we have developed innovative solutions (both in terms of technologies and algorithms) for the following aspects: fabrication of soft organ models starting from CT images, surgical planning and execution of movement of robot arms in contact with a deformable environment, designing a surgical interface minimizing the cognitive load of the surgeon supervising the actions, intra-operative sensing and reasoning to detect normal transitions and unexpected events. All these technologies have been integrated using a component-based software architecture to control a novel robot designed to perform the surgical actions under study. In this work we provide an overview of our system and report on preliminary results of the automatic execution of needle insertion for the cryoablation of kidney tumours

Distributed Control of Microscopic Robots in Biomedical Applications

Current developments in molecular electronics, motors and chemical sensors could enable constructing large numbers of devices able to sense, compute and act in micron-scale environments. Such microscopic machines, of sizes comparable to bacteria, could simultaneously monitor entire populations of cells individually in vivo. This paper reviews plausible capabilities for microscopic robots and the physical constraints due to operation in fluids at low Reynolds number, diffusion-limited sensing and thermal noise from Brownian motion. Simple distributed controls are then presented in the context of prototypical biomedical tasks, which require control decisions on millisecond time scales. The resulting behaviors illustrate trade-offs among speed, accuracy and resource use. A specific example is monitoring for patterns of chemicals in a flowing fluid released at chemically distinctive sites. Information collected from a large number of such devices allows estimating properties of cell-sized chemical sources in a macroscopic volume. The microscopic devices moving with the fluid flow in small blood vessels can detect chemicals released by tissues in response to localized injury or infection. We find the devices can readily discriminate a single cell-sized chemical source from the background chemical concentration, providing high-resolution sensing in both time and space. By contrast, such a source would be difficult to distinguish from background when diluted throughout the blood volume as obtained with a blood sample

Code of Ethics for Robotics: A Surgery Case Study

The future of robotics is broad and varied. New developments that delve deeper into the use of artificial intelligence and automation, for practices ranging from driver less cars to doctor less surgeries, calls for a defined code of cultural, ethical, and legal regulations that can guide engineers around the most delicate issues that may arise. With the reputation of the field resting on the evolution of a code of ethics this paper compares and discusses existing literature on the subject. With the foundation and influence of the existing literature this paper proposes a refined code of ethics designed to target the specific area of robotic engineering. It is also designed to remain applicable for future developments in the field. Having laid out the code it is then be applied to a case study focusing on surgery robots. Final recommendations and conclusions are made to advise future developments for an ethical code targeted at robotic engineers
