A collaborative robot for COVID-19 oropharyngeal swabbing.

ABSTRACT: The coronavirus disease 2019 (COVID-19) outbreak has increased mortality and morbidity world-wide. Oropharyngeal swabbing is a well-known and commonly used sampling technique for COVID-19 diagnose around the world. We developed a robot to assist with COVID-19 oropharyngeal swabbing to prevent frontline clinical staff from being infected. The robot integrates a UR5 manipulator, rigid-flexible coupling (RFC) manipulator, force-sensing and control subsystem, visual subsystem and haptic device. The robot has strength in intrinsically safe and high repeat positioning accuracy. In addition, we also achieve one-dimensional constant force control in the automatic scheme (AS). Compared with the rigid sampling robot, the developed robot can perform the oropharyngeal swabbing procedure more safely and gently, reducing risk. Alternatively, a novel robot control schemes called collaborative manipulation scheme (CMS) which combines a automatic phase and teleoperation phase is proposed. At last, comparative experiments of three schemes were conducted, including CMS, AS, and teleoperation scheme (TS). The experimental results shows that CMS obtained the highest score according to the evaluation equation. CMS has the excellent performance in quality, experience and adaption. Therefore, the proposal of CMS is meaningful which is more suitable for robot-sampling.

Assessing the Impact of a Training Initiative for Nasopharyngeal and Oropharyngeal Swabbing for COVID-19 Testing.

Project description:ObjectiveThe accuracy and reliability of COVID-19 testing are critical to limit transmission. After observing variability in testing techniques, we otolaryngologists at a tertiary medical center initiated and evaluated the impact of nasopharyngeal and oropharyngeal swabbing training, including video instruction, to standardize sampling techniques and ensure high-quality specimens.MethodsParticipants in the training were employees (N = 40). Training consisted of an instructional video on how to perform nasopharyngeal and oropharyngeal swabs and a live demonstration. Participants completed pre- and posttraining surveys assessing their knowledge and confidence in performing nasopharyngeal and oropharyngeal swabs. They then performed swabbing on partners, which was graded per a standardized checklist.ResultsMean scores for knowledge-based questions and confidence in swabbing were significantly higher after the training session (both P < .001). All participants scored ≥6 of 8 on the posttraining checklist. Ninety-five percent rated the video as very or extremely useful.DiscussionSpecialized instruction for nasopharyngeal swabbing improved participants' knowledge-specifically, the appropriate head position and minimum swab time in nasopharynx-and their confidence. After the training, their swabbing execution scores were high.Implications for practiceVideo-assisted hands-on instruction for nasopharyngeal swab sampling can be used to standardize teaching. When prompt and accurate testing is paramount, this instruction can optimize procedural technique and should be used early and often. In addition, there may be a professional responsibility of otolaryngologists to participate in such initiatives.

COVID-19: Nasal and oropharyngeal swab.

Project description:Performing a proper nasal and oropharyngeal swab procedure is essential in the screening of COVID-19 infection. The video illustration of nasal and oropharyngeal swab is presented (Video S1). To correctly perform the nasopharyngeal swab, the patient must be seated comfortably with the back of their head against the headrest. The swab is inserted in the nose horizontally, along an imaginary line between the nostril and the ear. Oropharyngeal sampling is easier to perform. The swab is directed toward the rear wall of the oropharynx and it is rotated a few times before removal. After taking the sample, it is necessary to insert both swabs in the same tube, breaking the rod with one swift and controlled movement. Finally, carefully reset the cap. It appears to be extremely important to properly collect nasopharyngeal and oropharyngeal swabs in order to minimize the false negative rate among COVID-19 positive patients.

Affect-Driven Learning of Robot Behaviour for Collaborative Human-Robot Interactions.

Project description:Collaborative interactions require social robots to share the users' perspective on the interactions and adapt to the dynamics of their affective behaviour. Yet, current approaches for affective behaviour generation in robots focus on instantaneous perception to generate a one-to-one mapping between observed human expressions and static robot actions. In this paper, we propose a novel framework for affect-driven behaviour generation in social robots. The framework consists of (i) a hybrid neural model for evaluating facial expressions and speech of the users, forming intrinsic affective representations in the robot, (ii) an Affective Core, that employs self-organising neural models to embed behavioural traits like patience and emotional actuation that modulate the robot's affective appraisal, and (iii) a Reinforcement Learning model that uses the robot's appraisal to learn interaction behaviour. We investigate the effect of modelling different affective core dispositions on the affective appraisal and use this affective appraisal as the motivation to generate robot behaviours. For evaluation, we conduct a user study (n = 31) where the NICO robot acts as a proposer in the Ultimatum Game. The effect of the robot's affective core on its negotiation strategy is witnessed by participants, who rank a patient robot with high emotional actuation higher on persistence, while an impatient robot with low emotional actuation is rated higher on its generosity and altruistic behaviour.

Synchronization-based control for a collaborative robot.

Project description:This article introduces a new control scheme for controlling a robotic manipulator in a collaborative task, allowing it to respond proactively to its partner's movements. Unlike conventional robotic systems, humans can operate in an unstructured, dynamic environment due to their ability to anticipate changes before they occur and react accordingly. Recreating this artificially by using a forward model would lead to the huge computational task of simulating a world full of complex nonlinear dynamics and autonomous human agents. In this study, a controller based on anticipating synchronization, where a 'leader' dynamical system is predicted by a coupled 'follower' with delayed self-feedback, is used to modify a robot's dynamical behaviour to follow that of a series of leaky integrators and harmonic oscillators. This allows the robot (follower) to be coupled with a collaborative partner (leader) to anticipate its movements, without a complete model of its behaviour. This is tested by tasking a simulated Baxter robot with performing a collaborative manual coordination task with an autonomous partner under a range of feedback delay conditions, confirming its ability to anticipate using oscillators instead of a detailed forward model.

A Flexible Transoral Robot Towards COVID-19 Swab Sampling.

Project description:There are high risks of infection for surgeons during the face-to-face COVID-19 swab sampling due to the novel coronavirus's infectivity. To address this issue, we propose a flexible transoral robot with a teleoperated configuration for swab sampling. The robot comprises a flexible manipulator, an endoscope with a monitor, and a master device. A 3-prismatic-universal (3-PU) flexible parallel mechanism with 3 degrees of freedom (DOF) is used to realize the manipulator's movements. The flexibility of the manipulator improves the safety of testees. Besides, the master device is similar to the manipulator in structure. It is easy to use for operators. Under the guidance of the vision from the endoscope, the surgeon can operate the master device to control the swab's motion attached to the manipulator for sampling. In this paper, the robotic system, the workspace, and the operation procedure are described in detail. The tongue depressor, which is used to prevent the tongue's interference during the sampling, is also tested. The accuracy of the manipulator under visual guidance is validated intuitively. Finally, the experiment on a human phantom is conducted to demonstrate the feasibility of the robot preliminarily.

Swabbing Thoroughly People for COVID-19 Positivity. Insights on the Main Bio-analytical and Microbiology Bias and Concerns.

Project description:Thorough swabbing is becoming an increasing approach to fight COVID-19 transmission, particularly among asymptomatic subjects, who are thought to represent the majority of potentially-contacting people. Particularly in the current management of COVID-19 emergency, the 3T approach, i.e., testing, tracing and treating, is felt as particularly crucial to fight COVID-19 pandemic. Aside from the time-consuming, cost expensive and the many burdensome issues associated with a thorough swabbing, adopting easy-to-make criteria such as "drive-thru-swab" may exacerbate the burden of critical biases and pre-analytical errors, which may impair the analytical reliability of these tests. This manuscript addresses some major points about.
