The authors would like to thank all the volunteers who participated in the experiments. The experimental results demonstrate that the proposed semi-autonomous robotic system yielded a continuous, smooth and collision-free motion trajectory for the end-effector approaching the target. The proposed non-invasive and hybrid Gaze-BMI may provide an alternative solution that diminishes medical risks, at the costs of reduced control accuracy and number of controlled DoFs. Figure 3. for able-bodied or mildly impaired people may no longer be applicable. Then the identification of perspective transformation was accomplished with the 4-point getPerspective procedure from the OpenCV toolbox. (2) Distinguished from previous shared control strategies for non-invasive driven assistive robots where the control authority switches discretely between the user and the autonomy, our shared control paradigm combines user input and the autonomy at all times with the dynamical combination regulation, and this is thanks to the continuous-valued velocity control via the new HRI. BX and YW performed the experiment. If a significant main effect was found, we further conducted the Tukey’s honestly significant difference post hoc test for multiple comparisons. A definition of supervised learning with examples. To increase usability and reduce the cognitive burden of the user, the shared control strategies have been commonly adopted by adding autonomous supportive behavior to the system. To accomplish this, Tyndall will incorporate a series of "semi-autonomous robot dogs" into patrol regiments, becoming "one of the first" Air Force bases to implement such technologies. For the proposed hybrid gaze-BMI, the continuous modulation of the movement speed via the motor intention occurs seamlessly and simultaneously to the unconstrained movement direction control with the gaze signals. A proof-of-concept implementation of the proposed semi-autonomous robotic system was carried out using a 5-Dof robotic arm (Dobot Arm, Shenzhen Yuejiang Technology Co Inc., China). Given the final goal of developing affordable and usable assistive technology, a low-cost commercial EEG acquisition headset, Emotiv EPOC + (Emotiv Systems Inc., United States), is used to record the EEG signals. Afterward, the segmented signals were bandpass-filtered between 8 and 30 Hz with a 5th-order Butterworth bandpass temporal filter. (2019a). doi: 10.1007/s10514-017-9622-4, Nicholas, R., Paul, N., and Siddhartha, S. (2013). The eye tracker was mounted at the bottom of the host PC monitor, it detects the user’s pupils and then projects the pupils onto the screen, i.e., the outputs of the eye tracker sensor system are the user’s gaze locations on the screen. My plan is as follows. An overview of plum color with a palette. IEEE Trans. Subsequently, the commonly adopted spatial filtering method for the feature extraction in MI-based BMI, i.e., common spatial pattern (CSP), was applied on the signals.

Shared autonomy via hindsight optimization for teleoperation and teaming. Rep. 6:38565. Figure 1. A definition of autonomous robot with examples. The assistive robotic system consists of an eye-tracker, a device for recording EEG signals, a web camera, a robotic arm, a computer, and a monitor. doi: 10.1109/TNSRE.2010.2049862, Robinson, N., and Vinod, A. P. (2016). I want to create a semi-autonomous robot for navigating within buildings. In Figure 9, we provide a representative comparison of performance with direction shared control (SCDS) and without direction shared control (SCS) by plotting the trajectories of the robotic arm end-effector from all the trials for subject 6. After a successful target object selection indicated by the augmented reality (AR) feedback (illustrated in subsection “Camera, GUI and Computer Vision”), the hybrid gaze-BMI automatically entered the continuous-valued velocity control mode in stage 2 (the horizontal reaching). Brain-computer interfaces using sensorimotor rhythms: current state and future perspectives. It firstly operates in a discrete selection mode for inputting the user’s intended target location in stage 1, and is then automatically switched to operate in a continuous-velocity control mode for inputting the user’s velocity commands to move the robotic arm end-effector horizontally toward the target in stage 2; (2) Camera and Graphical User Interface (GUI), which provide the live scene of the robotic arm workspace for the normal and enhanced visual feedback as well as the coordinate transformations from camera coordinate system to the robot coordinate system for all the three stages. doi: 10.1109/TBME.2014.2312397, Yuan, H., Perdoni, C., and He, B. For metrics measured per trial (i.e., EETL and CT), we averaged the data across all ten trials for each paradigm, enabling us to treat each user as one independent datapoint in the statistical analysis. The raw gaze data were transmitted to the computer via USB 3.0 at a sampling rate of 60 Hz. In other words, none of the aforementioned studies using the multi-class MI-based BMI are able to implement an intuitive and effective interface capable of providing continuous-valued velocity (i.e., including the movement direction and speed simultaneously) control signals for a robotic device. Figure 2 introduces the block diagram of the proposed semi-autonomous robotic system, which consists of four main functional blocks: Figure 2. Shademan et al . Such a continuous-valued velocity (movement direction and speed) control advantage means that not only the end-effector could follow natural movement paths determined by the user in real-time (rather than following predefined ones, Rebsamen et al., 2010; Zhang et al., 2017), but also that the end-effector is always moving as long as it is volitionally directed by the user during the horizontal reaching task. Another future study will extend the current 2D gaze tracking into 3D one with a wearable eye-tracker as in Abbott and Faisal (2012) and Li S. et al. The selected target highlighted with a virtual rectangle frame surrounding it. One of the future works will be devoted to re-implementing the detection of the mental state related to motor imagery using a medical EEG acquisition system. With the hybrid interface in such a mode, the user had to constantly specify the sequential locations in GUI, to which he/she desires the end-effector to move, using the eye-tracker. The paradigm is devised in this manner to maintain as much volitional control as possible while providing the assistance for the most difficult parts of the task. Therefore, to reduce the difficulty, we provided assistance for the user, deriving from the robot autonomy. IEEE Eng. Slanzi, G., Slanzi, J. As shown in the Figure 13, the robot autonomy provided little assistance in the beginning (the end-effector was far away from the target object) as the certainty of system-inferred user intention for reaching the target was low.

All rights reserved. For each online trial, the participant attempted to move the robotic arm end-effector sequentially toward the target in the horizontal plane while avoiding obstacles along the path with the proposed continuous-velocity control-based hybrid gaze-BMI. Autonom. The principle for the shared control in direction. The duration of the BMI calibration usually did not exceed 5 min.

One can observe that EETLs obtained with SCDS or SCD were generally shorter than those obtained with SCS and MC. Most fully autonomous systems, … was implemented automatically. Lancet 381, 557–564. For the last 10-15 years, the idea of robotics has largely involved teleoperated mobile robots equipped with cameras being used to get eyes on something out of reach. Eng. Robot. To this end, the hybrid gaze-BMI has been proposed to predict the web user’s click intention (Slanzi et al., 2017), explicit selection of the target in robot reaching (Frisoli et al., 2012), and ability to carry out grasping (McMullen et al., 2014; Zeng et al., 2017) and pushing tasks (Schiatti et al., 2017). A semi-autonomous robot designed to be at the frontlines of this war against the virus. In the direction controller, the constant parameter b is set to −0.55, and d = 25 defines the distance so that β = 0.5, xdrepresents either the distance between the robotic arm end-effector and the obstacle or that between the end-effector and the target object. In addition, the movement speed is usually not controlled or merely coarsely modulated by the signal’s time-resolved power. For this purpose, in the calibration phase (executed only once), four points were selected on the screen with known coordinates on the robot arm frame of reference. In other words, the movement direction shared controller improved task performance mainly by stabilizing the movement near the target or obstacles to eliminate unintended or inaccurate movements that could interfere with the task completing. As delivery times drop to hours, or even minutes, last-mile solutions have become a critical focus for Amazon and Yandex, along with grocery and food delivery companies . Besides, the user can only generate actions synchronously, resulting in a certain amount of time spent idle for users and thus slowing down the system. Such offline classification performance was in line with the existing BMI studies (Martinezleon et al., 2016; Schiatti et al., 2016) using a Emotiv EPOC headset. (2017). Med. Front. Shared control of a robotic arm using non-invasive brain–computer interface and computer vision guidance. Specifically, when a human decides to pick up an object, he/she usually first looks at the object, and then performs the hand reaching under the visual guidance. Abbott, W. W., and Faisal, A. (2016). Copyright © 2020 Zeng, Shen, Hu, Song, Xu, Li, Wang and Wen. Front. Abstract: This work describes a semi-autonomous robot for rescue operations, nicknamed RAPOSA (FOX in English). Upon observing the virtual rectangle appearing around the target, the user got to know that the position of the target has been successfully communicated to the assistive robotic system. 115, 121–129. However, one of the main limitations of gaze tracking is that the input may be intention-free (without necessarily selecting there), even though the user stares at somewhere on the computer screen. doi: 10.1016/j.eswa.2015.11.015, McMullen, D. P., Hotson, G., Katyal, D. K., Wester, B. According to the experimental results shown in the bottom subfigure of Figure 12, the evolving trend of the mean speed without assistances from the robot autonomy (i.e., mean speed obtained with SCD) was indeed found to be generally aligned with that of the posterior probability value of the MI state during the reaching task. Compared to a system without assistances from robot autonomy, it significantly reduces the rate of failure as well as the time and effort spent by the user to complete the tasks. June 15, 2020, 8:15 AM . During the offline calibration phase, the EEG signals for the motor imagery state, and the rest state were recorded. Thanks to the application of the shared control in both the movement direction and speed, the SCDS paradigm reduced the task difficulty by adding autonomous supportive behavior to the system. These two shared controllers are described in detail in the following sub-sections. (2017). In fact, gaze constitutes an intuitive input for continuous-valued positions in 2D control tasks (e.g., moving a cursor freely on a computer screen) without extensive training. A Publ. An intention-driven semi-autonomous intelligent robotic system for drinking. Human cooperative wheelchair with brain–machine interaction based on shared control strategy. Appl. (2017). It was calculated using a sigmoid function to enable smooth and continuous blending between the user and robot autonomy command: where xd denotes the distance from the robotic arm end-effector to the position of the target object on the horizontal 2D plane parallel to the table, a = −0.4 is a constant parameter, and c defines the distance so that α = 0.5. It lasted less than 1 min for each subject, during which the user gazed at seven calibration dots sequentially appeared on the monitor. Transferring brain–computer interfaces beyond the laboratory: successful application control for motor-disabled users. Plus.ai. Robot. The EETLs for each subject and across subjects (the across-subjects performance difference with statistical significance is marked by “*”, p < 0.05). Written informed consent was obtained from each subject. Biomed. The experiments are performed by a number of able-bodied volunteers, and the results show that the new HRI-driven semi-autonomous assistive robotic system allows for a continuous, smooth, and collision-free motion trajectory for the end-effector approaching the target, significantly reducing the rate of failure as well as time and effort spent by the user to complete the tasks.

In this way, the paradigms allow the user to directly control the majority of the movement, while smoothly increasing the assistance from robot autonomy during the most difficult parts (e.g., collision avoidance, target approaching) of the task for the user, reaching a balance between the user’s perceived control and the reliable assistance provided by the robot autonomy. doi: 10.1007/978-3-642-02091-9_1, Hong, K. S., and Khan, M. J. (2017), the user exploited the interface in a discrete selection mode to specify the intended target location for the system by firstly gazing at the center of the target object in GUI and then issuing the confirmation once the posterior probability value for the MI state exceeded the threshold (0.6 in our experiment). An overview of the Gilded Age of American history. A ‘pack’ of four dog … However, the surgical risks associated with current invasive BMIs may outweigh the advantages of effective robotic arm control. It indicated that the adopted BMI calibration method could provide an applicable BMI decoder for our experiments. Hybrid brain–computer interface techniques for improved classification accuracy and increased number of commands: a review. From Figure 9, we observed that the reaching trajectories generated with assistance from the direction shared controller were smoother and more direct than those without. The block diagram of the proposed semi-autonomous robotic system. Combining eye tracking, pupil dilation and EEG analysis for predicting web users click intention. In addition, the infrequent switching between tasks (e.g., from reaching to grasping, from grasping to delivering, from delivering to releasing, etc.) Volvo Delicately Dances Into the Semi-Autonomous Future The Swedish automaker wants to avoid the space between human and robot drivers—but that may prove impossible. Future studies will investigate advanced BMI classification methods for recognizing multiple mental states, in order to trigger the task switching. • The mobile robot takes pictures of hidden parts of segmental, slab, girder and arch bridges. Subsequently, the system automatically switches the hybrid gaze-BMI into a continuous-velocity control mode (refer to sub-section “Two operation modes of the hybrid gaze-BMI control”). Then, the SRR identified the proportion for successful reaching trials out of the 10 trials applied with the four paradigms, measuring the effectiveness in improving the robot control precision for achieving the user’s goal. The … Another line of paradigms enables users to have more control with high-level user commands (e.g., movement directions of the end-effector or the wheelchair, etc. For the gaze tracking, a consumer-level desktop eye tracker, EyeX (Tobii AB Inc., Sweden), was employed. Kris Osborn. In specific, the reach-and-grasp task was divided into three stages. |, Creative Commons Attribution License (CC BY). For illustrating the dynamic speed compensation process above, Figure 13 shows the arbitration factor for the robot autonomy from the speed shared controller in a normalized time scale. Researchers from Nanyang Technological University, Singapore (NTU Singapore) have developed a semi-autonomous robot that can disinfect large surfaces quickly.The researchers are planning to have public trials to support Singapore's fight against COVID-19. (Berlin: Springer Berlin Heidelberg), 1–27. Compared to a system without assistances from robot autonomy, it significantly reduces the rate of failure as well as the time and effort spent by the user to complete the tasks. Results are drawn from major databases, excluding papers not experimentally implemented on real robots. 11:24. doi: 10.3389/fnbot.2017.00024, Chen, X., Zhao, B., Wang, Y., and Gao, X. Res.

HZ, YS, and YW analyzed the data and wrote the manuscript. ), while fully relying on the autonomy to generate the precise and safe low-level reactive robot motions (e.g., target approaching, collision avoidance, etc.). The MC paradigm yielded an SRR of 66% with subject 7 being the lowest (40%). Part A 42, 2–14. J. Neural Eng. Namely, as in our previous work (Zeng et al., 2017), the target (a cuboid in the current study) was highlighted with a virtual rectangle frame surrounding it (Figure 4) when the cursor (gaze point) was over the center of it and the motor imagery state was decoded from the BMI. IEEE Trans. When combined with RFID-tagged products and equipment, these machines can now conduct their own inventory sweeps autonomously at schedules determined by the warehouse. The overall average classification accuracy across the subject was 82.1% with a standard deviation of 4.8%. 2, 4–16. The semi-autonomous surgical robot system can be achieved with vision information. All the users were able to employ the hybrid gaze-BMI for moving the end-effector sequentially to reach the target across the horizontal plane while also avoiding collisions with obstacles. • The mobile robot can perform an inspection while traffic is maintained on the bridge. A reasonably comprehensive list of information technologies. The range of standard deviations is indicated with shaded background in the two subfigures of Figure 12. Furthermore, the presented shared control paradigm allows the user to directly control the majority of the movement while smoothly increasing the assistance from robot autonomy the during the most difficult parts (e.g., collision avoidance, target approaching, etc.) (2016). Artif. The EETLs for each subject and across subjects are presented in Figure 8. (2013). The developers also could specify the orientation of the gripper in order to grasp an object with a certain orientation in the workspace. The shared control paradigm maintained as much volitional control as possible, while providing the assistance for the most difficult parts of the task. Non-invasive BMI, in particular the widely accepted electroencephalogram (EEG)-based BMI, provides a desirable alternative, and it is thus adopted in this study. A successful reaching trial was defined as one during which the end-effector did not collide with obstacles before entering the pre-grasping zone. 11:60. doi: 10.3389/fnbot.2017.00060, Zhang, R., Li, Y., Yan, Y., Zhang, H., Wu, S., Yu, T., et al.
