This paper presents an advancedcontrol error processing to enable the feedback position control of an industrial robot based on external sensor signals for dual-stage actuation. A measurement module comprising a magnetically levitated platform with an integrated 3D measurement tool is mounted as end effector on the industrial robot. The industrial robot is used to maintain the measurement platform within its limited actuation range, while actively tracking a sample in motion. The measurement module provides the short stroke but precision positioning of the measurement tool relative to a sample surface in 6-DoF. For a feedback controlled repositioning of the industrial robot’s tool center point based on the internal measurement platform’s position signals, a real-time interface is used. The implementation of the advancedcontrol error processing successfully demonstrates the active tracking of a sample in motion, with residual tracking errors of 473 nm rms in sample-motion direction.

We report a smart wearable glove that can wirelessly control the robotic hand. The developed Miura-ori structured AgNWs embedded conductive elastomer wire shows good stretchability (similar to 50%), low resistivity (0.00075 Omega center dot cm), and good resistance reliability. The integrated formed bending sensor and the wires make the sensing unit more robust than traditional bonded metal wires. The further development of circuit design and Bluetooth transmission successfully build the human-machine interfaces (HMIs) between humans and robots.

Steady-state somatosensory evoked potentials (SSSEP)-based brain-computer interface (BCI) has been developed to control real-life assisting robots, such as an exoskeleton for body-disabled patients. Although the SSSEP-BCI system has been advanced by various research groups, improving the accuracy is required for applying stable control of the appliance. Moreover, the SSSEP-BCI study on body-disabled patients is still required to confirm applicability. In this study, the convolutional neural network (CNN) was applied to the SSSEP-BCI and compared with the regularized linear discriminant analysis (RLDA) as the widely used method. For extracting the spatial feature, the common spatial pattern (CSP) was used in both methods, and the efficiency of the CNN was validated via the SSSEP data from five healthy subjects and two spinal cord injury (SCI) patients. As a result of 9-fold cross-validation, the CSP-CNN method showed significantly higher accuracy than CSP-RLDA by 7.8% (Healthy subject) and 7.2% (SCI patients). We can therefore conjecture that CNN can improve the performance of SSSEP-BCI.

Smart wearable devices are becoming increasingly popular in daily life due to recent technological advances. They have various applications in the medical field (e.g., heart rate monitoring, blood pressure, blood oxygen), industrial field (e.g., worker assistance, gesture-based process control, recognition of unsafe conditions), and in the field of interactive virtual games (e.g., virtual reality, augmented reality). However, these devices must achieve their goals while meeting human needs during their use, such as wearability and adaptability. They must therefore be flexible, lightweight, and easy to understand with an intuitive interface. To fulfil these requirements, the challenge is to integrate flexible sensors and actuators into common clothing fabrics, minimizing the hardware needed and maximizing the wearer's comfort. In this paper, we present a novel dielectric elastomer (DE)based wearable device that can provide tactile feedback on its wearer. It consists of a pouch-like air pocket with a passive and an active silicone membrane (DE). This pouch or bubble is inflated with air pressure, which acts as the necessary bias mechanism pre-stretching both the passive and the active DE membrane. The device is designed in a way that the passive membrane side of the pouch is in contact with the wearer's skin. In addition, to better understand how the passive membrane affects the overall system behavior, we provide experimental characterization studies on design parameters (i.e., thickness and initial pretension of the passive silicone membrane) for different internal pressure values. This results in the membranes having many layers with no pretension to minimize leakage.
