“…The superior perception of the environment and precise robot controlling methods provided by advances in artificial intelligence have enabled the development of robotic solutions with the intelligence and maneuverability necessary to accurately perform challenging medical tasks under supervised autonomy (Beasley, 2012; Chen et al, 2020; Coelho et al, 2010). Nevertheless, a major problem with their integration into clinical practice is related to the increased demand for international standards for patient safety and security (Gualtieri et al, 2022; Haidegger, 2019; Kuhl et al, 2020). A strategy may rely on incorporating a commercially available robotic arm that already fulfills specific safety and security standards, reducing the effort to bring these solutions to the market.…”

While designing an end‐effector tool for a specific task using an already available robotic arm is a common strategy for developing robot‐based solutions, it is subject to the designer's subjective biases, especially in the medical robotics field. Consequently, this approach can result in suboptimal solutions that may limit the performance of the robotic arm and the overall system. This work introduces a novel framework for developing a virtual scenario that enables the robust optimization of design guidelines for robotics‐based medical solutions. The proposed framework aims to address the issue of subjectivity involved in the design process, improving the reliability and accuracy of the robotic system. Specifically, it aims to find the optimized 3D positioning of the Tool Center Point and the robot base that takes full advantage of the robotic arm kinematics. The feasibility of the proposed methodology is validated for designing a system for robotic‐guided vascular laser treatments. First, a simulated treatment environment is constructed to compute the optimal trajectories to treat a wide population of synthetic human models. Next, a design optimization methodology based on robot task performance metrics is developed. Overall, the proposed design guidelines allowed the performance of 94.1% of the treatment trajectories free of collisions with median precision of around 0.5 mm while guaranteeing high manipulability. Thus, proving the added value of the proposed strategy and showing the potential for promoting the development of optimized robotics‐based solutions.

“…The progress in artificial intelligence, with improved robot controlling strategies and environment perception, enabled the development of image-guided robotic solutions to execute challenging medical tasks with supervised autonomy and performance, comparable to experts [ 9 , 10 , 11 , 12 ]. To introduce the advantages of medical robotics for laser therapy, the development of personalized solutions to account for the task-specific requirements is fundamental [ 13 , 14 , 15 , 16 ]. However, the development of a robot-based system to execute a specific task is challenging and dependent on the designer’s subjectivity, specifically in medical robots.…”

The increase of the aging population brings numerous challenges to health and aesthetic segments. Here, the use of laser therapy for dermatology is expected to increase since it allows for non-invasive and infection-free treatments. However, existing laser devices require doctors’ manually handling and visually inspecting the skin. As such, the treatment outcome is dependent on the user’s expertise, which frequently results in ineffective treatments and side effects. This study aims to determine the workspace and limits of operation of laser treatments for vascular lesions of the lower limbs. The results of this study can be used to develop a robotic-guided technology to help address the aforementioned problems. Specifically, workspace and limits of operation were studied in eight vascular laser treatments. For it, an electromagnetic tracking system was used to collect the real-time positioning of the laser during the treatments. The computed average workspace length, height, and width were 0.84 ± 0.15, 0.41 ± 0.06, and 0.78 ± 0.16 m, respectively. This corresponds to an average volume of treatment of 0.277 ± 0.093 m3. The average treatment time was 23.2 ± 10.2 min, with an average laser orientation of 40.6 ± 5.6 degrees. Additionally, the average velocities of 0.124 ± 0.103 m/s and 31.5 + 25.4 deg/s were measured. This knowledge characterizes the vascular laser treatment workspace and limits of operation, which may ease the understanding for future robotic system development.

“…Additionally, few facilities have worked with researchers in the development of new technology, as most are too busy [5,12,13]. As a result, many scholars have only involved users in the later phase of the system/service development process, i.e., test and evaluation [14]. In contrast, as safety issues are significant for assistive/medical devices, recent studies have emphasized the importance of intensive user involvement and risk management from the early phases of the design process [14].…”

This paper proposes a user-centered design (UCD) method and demonstrates the assistive device design, incorporating user involvement and the risk management approach throughout the design process, in a Japanese day-care facility for older adults. The study focused on the lunchtime problem, where there is a limited number of nursing staff for meal assistance and supervision of users to ensure their safety. An abnormal posture notification system that met the technical/functional and user requirements was successfully designed by conducting participant observations and using human error-proofing principles. This approach enabled timely identification of proper solutions in the care facility and areas for improvement, and thus the discovery of users and use-cases that were not initially envisioned.
