Extraction of features is a key process in image-based visual servo. However, existing image processing methods are difficult to segment the target foreground and cannot overcome distracting factors, such as background and illumination, resulting in reduced accuracy of feature extraction. Therefore, target foreground segmentation is a critical problem in image-based visual servo tasks. In this paper, a method for image foreground segmentation and visual servo control based on small data training is proposed. Semantic segmentation is achieved by training a small number of images. Focusing on the target artefact region and blurring the background are also achieved to avoid its influence on feature recognition, especially for industry parts. It is shown that recognition and segmentation under different lighting conditions can be obtained, reducing the interference of lighting on visual servo. Experimental results show that the proposed method is effective in visual servo controlapplications.

This paper investigates the key design parameters such as body aspect ratio, leg structure proportions, and the ratio of body width to overall width of an amphibious crab-like robot tailored for operations in seabed and near sidewall narrow environments. On this basis, the walking leg posture which is easy to sense the environment and the standing leg posture which is high stability are designed, and the foot landing points of the robot in the surf zone have also been optimized.

This paper presents the design and control of a novel microrobot that utilizes two distinct magnetic locomotion methods, a combination of rotating and gradient field control, for precise micro-object manipulation using multiple end-effectors. Rotating magnetic fields induce a tumbling locomotion mode to increase the movement speed and decrease issues associated with stiction and locomotion over rough surfaces. The gradient field control allows for precise manipulation using the end-effectors, which include a pointed tip for splitting groups of objects and a blunt end for pushing or capturing objects. The microrobot is fabricated using a two-photon polymerization 3D printer, allowing for the precise reproduction of complex geometries and designs. The potential applications of this technology in the medical field are discussed, highlighting the potential for in vitro cellular manipulation.
Amidst the widespread global challenges, this research delves into examining how advanced technology and automation can be incorporated into agriculture technology to address problems like reliance on manual labor, en...

There has been a rising demand for more efficient and secure processing on the edge to cope with the number of emerging Internet of Things (IoT) applications. These applications scale from low-duty cycles high-performance tasks to high-duty cycle ultralow power operations. Embedded FPGAs (eFPGAs) can address many of these demands given their flexibility compared to ASIC, low latency, and lower energy consumption compared to CPUs. eFPGAs allow for post-silicon manufacturing patch-ability, adaptive performance, and on-chip control of large SoCs. This paper presents the implementation of eFPGA tailored for secure, efficient, and flexible System-On-Chip (SoC) management. The eFPGA acts as the heart of a Security Management Unit (SMU), which is part of a larger secure SoC platform that combines a True Random Number Generator (TRNG), an AES engine, and a NIST-compliant Lightweight cryptographic engine (LWC). Fabricated on 22nm CMOS technology, the eFPGA was used to dynamically manage the security policies of different IPs in the SoC under a proposed threat model. We report the performance of these applications, showing the benefits the embedded fabric provides.
