This paper describes a high-bandwidth control system design procedure for a MEMS force sensor equipped with an adjustable stiffness mechanism. When the force sensor comes into contact with a sample that has a stiffness at least comparable to its longitudinal stiffness, the resulting mechanical contact causes the system to become stiffer. This change in stiffness can be seen through the rising resonance frequency and falling dc-gain. In order to maintain closed-loop stability of the system after contact, it is necessary to tune the controller parameters since they are originally designed for the nominal system. By implementing a control system that combines an inner damping loop with a tracking loop together with adaptive algorithms to re-tune the controllers after contact, we were able to obtain satisfactory closed-loop performance. Also, the stiffness adjustment mechanism provides additional means of tuning the system dynamics. The numerical and experimental results demonstrate that these control approaches significantly increase the force tracking bandwidth.

Thermoelectric generators (TEGs) are one of the most promising means of harvesting energy from the sun. However, the TEGs require a significant temperature difference to generate electricity, making it challenging to achieve high power output from solar radiation alone. Here, shadow-effect generators (SEGs) are connected with TEGs to form a shadow-thermoelectric system (STS), which exploits the natural shadow produced by the TEG to enhance the electrical power output by solar energy conversion. With the shadow enhancement, the open-circuit voltage of the STS is significantly increased by a factor of 115 compared to that of the single TEG. Furthermore, the STSs array is successfully combined with a photoelectrochemical cell to convert the intermittent solar energy into storable hydrogen energy. In addition, the STS can be applied as a touchless self-powered sensor which provides a useful control panel for human-machine interface (HMI). After combining the STS with signal processing circuits, the STS can control a virtual vehicle on computer smartly. In conclusion, STS is a promising design for energy harvesting and touchless self-powered sensing. This research provides valuable insights for the development of efficient solar energy conversion and new possibilities for HMI.

A key aspect of robotic systems include the ability to recover from an error and re-planning motion accordingly. The widespread acceptance of robotics in various sectors of society is inhibited by the degree of expertise required to program even the simplest error recovery strategies. Previous studies have addressed the complexity of robotics programming through user-interfaces, though they were not intended for novices or did not address error handling. This study discusses a framework developed that acts as an Interactive Robot Monitor and control system (IRMCS), that allows non-expert users to interface, understand and recover from errors in a robotic process. The framework takes the form of a system that is geared towards informing a user of a robotic process through the means of an activity diagram that allows for visual and intuitive human-robot interaction to support incremental learning and error handling of simple pick and place tasks. To evaluate the effectiveness of this approach, we conducted a control experiment with four novice users. The results revealed that by using the developed system, novices were able to recover from errors and were unsuccessful in the control condition. Furthermore, their subjective evaluation showed that these non-expert users are highly receptive to understanding and successfully implementing error recovery strategies in robotics.

The Autonomous Underwater Vehicle (AUV), as an important equipment technology for the development and utilization ofmarine resources, is cableless, which can reduce the influence of cable disturbance on AUV control. Compared with other types of underwater robots, it has obvious application advantages. However, the underwater environment is complex and constantly changing, and the AUV system is highly nonlinear, which poses challenges to the motion control of AUVs. The development of software for AUV motion control and status monitoring is designed by using Qt Creator software in this paper. The functions of the control system interface aremainly included in monitoring the communication status and data transmission of the control system interface with the NVIDIA control board, sending AUV motion commands, monitoring sensor data, and testing AUV power components. The AUV sensor data is retrieved and control commands are transmitted to the controller via unicast and multithreaded network communication based on the UDP/IP protocol. The Autonomous Underwater Vehicle (AUV) status can be displayed in real-time by the system interface, as demonstrated by experimental verification. Additionally, the control commands issued by the software can be promptly responded to by the AUV. A strong basis for future research on AUV motion control is established by these findings.

The exponential growth in Unmanned Aerial Vehicle (UAV) operations highlights the need for reliable and efficient airspace management. Ensuring the integrity and reliability of UAV Traffic Management (UTM) systems requires extensive testing, verification and validation. Overcoming these challenges is essential to guarantee that UAVs can be successfully integrated into operational airspace while maintaining the highest standards of safety and effectiveness. The development and improvement of virtual environment testing capabilities are critical to the advancement and rapid deployment of UTM services;however, building a high-fidelity digital environment that enables the development, verification and validation of UTM solutions in a compliant, scalable and sustainable manner remains demanding. By integrating MATLAB, Simulink, AirSim, Unreal Engine and Cesium, this study aims to extend the performance and functionality of a Digital Twin (DT) system. This integration leverages the sophisticated modelling capabilities of MATLAB and the advanced 3-dimensional (3D) simulation capabilities of AirSim. It also aligns with emerging trends in the aerospace sector, including autonomous flight and advanced sensing technologies. Firstly, co-simulation is explored as a potential technique to overcome the limitations of individual simulation software available on the market. The general principles are then applied to define and model a communication interface between the software selected to build the DT ecosystem. This interface is then evaluated by proposing practical and achievable test cases. Only after validating the proposed co-simulation framework, further experiments are introduced aiming at improving the vehicle and sensor model performance to obtain more accurate synthetic data. A series of experiments of increasing difficulty is proposed, starting from co-simulating a single sensor (GNSS, INS, LIDAR and camera) up to co-simulating the entire aircraft system for the develop

Constructing Ion-Bridging Structure with controlled Cracks in Plasticized PVC with Graphene for Highly Sensitive Strain sensor with a Wide Strain Range

The gauge factor (GF) is a critical parameter for strain sensors, but it faces limitations in achieving high GF values across a wide strain range. This work proposes a novel approach to enhance resistance changes within strains through synergistically combining controlled-crack sizing and an ion-bridging structure. This ion-conductive bridge forms at the interface between graphene and polyvinyl chloride (PVC) gel. Precise management of the crack initiation and propagation on graphene is achieved by controlling adhesion force between graphene and PVC gel. The resulting PVC gel/graphene-based strain sensor featuring this synergistic design exhibits exceptional sensitivity. It achieves GFs of 635 (epsilon < 40%), 1.5 x 10(6) (40% < epsilon < 80%), and 7.8 x 10(5) (80% < epsilon < 100%) over a 100% stretching range. This innovative ion-bridging construction enables precise control over bridge connectivity at the interface, mitigating graphene's inherent stretchability limitations and enhancing the GF of PVC gel, thereby enhancing strain sensor performance. The sensor detects bending motions and monitors angles within higher strain ranges, making it suitable for wearable applications in human motion tracking. Furthermore, a PVC-based posture correction system distinguishes various motions, including shoulder band stretching, armband stretching, and even full squats, showcasing its practicality and versatility.
