Vertebrate flyers perform intermittent flights as bounding or oscillating flights for power management. Intermittent flights and the resulting oscillating height during flapping and soaring provide the means of increasing speed without increasing flapping speed. These maneuvers and their robotic biomimicry have remained unexplored so far, which, if understood, can lead to aerial robot designs with endured flight operations. This works attempts to achieve robotic bounding flight using Northeastern's Aerobat platform. Aerobat can dynamically morph its wings by collapsing them rapidly during each gaitcycle. We present a launcher designed that allows bounding flight experimentation of Aerobat in a computer-aided fashion. We augmented Aerobat with a plural tiny thruster to stabilize its unstable roll, pitch, and yaw dynamics. This paper presents our controldesign based on extending Aerobat's states to accommodate unobservable aerodynamic forces and offers experimental results to support our proposed approach.

Evaluation of patient delirium in hospital Intensive Care Units (ICU) is a crucial and challenging task, with conventional assessments like CAM-ICU relying largely on verbal and physical communication, making it difficult for patients with limited physical abilities. To address this, we propose a system that integrates Brain-computer Interface (BCI) technology and a Socially Assistive Robot (SAR) through brain-controlled mental commands. In a pilot user study, we demonstrate how our system could successfully administer a version of the CAM-ICU to 13 medical professionals and students roleplaying various level of delirium severity. Our work reveals early usability and workload insights, and next steps to improve upon assessment classification accuracy and interaction design.

Recent advances in continuous-flow microfluidics have enabled highly integrated lab-on-a-chip biochips. These chips can execute complex biochemical applications precisely and efficiently within a tiny area, but they require a large number of control ports and the corresponding control logic to generate required pressure patterns for flow control, which, consequently, offset their advantages and prevent their wide adoption. In this article, we propose the first flow-control layer co-synthesis flow called Minicontrol, for continuous-flow microfluidic biochips under strict constraints for control ports, incorporating high-level synthesis, physical design, and controlsystemdesign simultaneously, which has never been considered in previous work. With the maximum number of allowed control ports specified in advance, this synthesis flow aims to generate biochip architectures with high execution efficiency and the corresponding controlsystems with optimized timing performance. Besides, the overall cost of a biochip can be reduced and the tradeoff between a controlsystem and execution efficiency of biochemical applications can be evaluated for the first time. The experimental results demonstrate that Minicontrol leads to high execution efficiency, low platform cost, as well as excellent timing performance, while strictly satisfying the given control-port constraints.

Digital Twins (DTs) serve as the backbone of Industry 4.0, offering virtual representations of actual systems, enabling accurate simulations, analysis, and control. These representations help predict system behaviour, facilitate multiple realtime tests, and reduce risks and costs while identifying optimization areas. DTs meld cyber and physical realms, accelerating the design and modelling of sustainable innovations. Despite their potential, the complexity of DTs presents challenges in their industrial application. We continue here the development of our approach to build an adaptable and trustable framework for building and operating DT systems - A Digital Twin Framework for Dynamic and Robust Distributed systems (D-RODS). D-RODS aims to address the challenges above, aiming to advance industrial digitalization and targeting areas like system efficiency, incorporating AI and verification techniques with formal support. We employ existing large-usage tools to illustrate the approach in development based on a synthetic adaptable use case.
Firstly, the electromagnetic compatibility design of the electromagnetic environment imaging early warning system for nuclear power plant is carried out in this paper. The electromagnetic compatibility design of the n...

Vibration-driven locomotion system is a relatively new branch of mobile robotics. The design variety of vibrationdriven robots is quite wide, while their controlsystems need constant improvement from the viewpoint of the robot's operational efficiency, accuracy, production, and maintenance costs. The purpose of this paper is the development, simulation, and practical implementation of a novel controlsystem for a mobile vibration-driven robot. The proposed controlsystem is based on Arduino hardware and software. The developed wheeled robot can be remotely controlled using the Bluetooth interface and the mobile phone with the corresponding Android application installed. The experimental prototype of the mobile robot is tested under different operational conditions (supplied voltages and forced frequencies) regulated by the developed controlsystem. The corresponding kinematic parameters of the robot's wheeled platform and the impact body are registered by the WitMotion accelerometers, and the experimental data are processed with the help of the WitMotion and MathCad software. The results of the presented research can be effectively used while designing and implementing mobile robotic systems for inspecting, cleaning, or maintaining the internal surfaces of various pipelines, tubes, vessels, intestines, etc.
