The exploration of snake locomotion has significantly informed the field of robotics, especially in the development of robots capable of navigating complex terrains. While most robotic designs traditionally rely on the assumption of uniform force distribution for movement, the nuanced agility of snakes suggests a more selective application of force across specific joints. This paper introduces a novel underactuated snake-like robot, drawing inspiration from the adaptive locomotion strategies observed in desert snakes. We propose a modular design, incorporating joints with varying functionalities, to enhance the robot's adaptability to diverse environmental challenges. Through simulation and experimentation on flat and inclined surfaces, we validate the effectiveness of this modular design in improving locomotive efficiency. © 2024 IEEE.

Crack localization and segmentation are essential for infrastructure maintenance and safety assessments, enabling timely repairs and preventing structural failures. Despite advancements in deep learning, crack segmentation remains challenging due to the need for real-time performance and computational efficiency. Existing methods often rely on large, resource-intensive models, limiting their practical deployment. We introduce CrackSegMamba, a novel model featuring Channel-wise Parallel Mamba (CPM) Modules, which achieves state-of-the-art performance with fewer than 0.23 million parameters and just 0.7 GFLOPs. CrackSegMamba reduces computational cost by 40-fold and parameter count by nearly 100-fold compared to existing models, while maintaining comparable accuracy. These features make CrackSegMamba ideal for real-time applications. Additionally, we present Crack20000, an annotated dataset of 20,000 concrete crack images to support further research and validation. Evaluations on the Crack500 [1] and Crack20000 datasets demonstrate that CrackSegMamba delivers comparable accuracy to leading methods, with significantly reduced computational requirements.

Nature has inspired many designs for micro-robot locomotion, particularly helical propulsion inspired by Escherichia coli and spermatozoa, which has found widespread applications in medical micro-robots for generating thrust at low Reynolds numbers. However, the design and fabrication of small robots for inspection tasks, especially in industrial settings filled with highly viscous liquids, remain challenging. In this paper, we propose a robot capable of locomotion in constrained environments filled with high-viscosity fluids. The robot is propelled by two helical propellers, enabling it to move effectively at low Reynolds numbers. The optimal parameters for the helical propellers are analyzed using Resistive Force Theory (RFT), and structures are designed and experimentally validated accordingly. Finite element analysis is employed to determine the suitable body for the robot. The robot prototype is fabricated using 3D printing. Finally, locomotion experiment was conducted to validate the feasibility of the robot moving in viscous liquid. © 2024 IEEE.

Place recognition serves as a fundamental component in tasks like loop closure detection and relocalization for mobile robots. Polar coordinate representations, such as Scan Context, which align with the data structure of range sensors, have become the most common data structure for point cloud descriptors in place recognition. While polar representations demonstrate the rotation invariance, they remain susceptible to translation variations. In this study, we introduce a novel approach: shifting the viewpoint of the original point cloud to construct the unified Scan Context, thereby mitigating translation variance. Our key concept focuses on identifying a stable, unified viewpoint for a given place and then pre-translating the point cloud accordingly. This naturally results in a descriptor devoid of translation variance. Importantly, within a given place, the viewpoint unification process tends to relocate the viewpoint to a similar position, irrespective of the original sensor perspective. In other words, the unified Scan Context becomes more closely associated with the place's structural characteristics than the physical location of the sensor. We validate our method through a series of comprehensive experiments encompassing synthetic scenarios and real-world datasets, showcasing its robustness in effectively handling translation variations. © 2024 IEEE.

Previous studies evaluated drivers’ knowledge of advanced driver assistance systems (ADAS) using different kinds of percentcorrectness-based mental model scores (MMS), which makes cross-study comparisons difficult. To resolve this issue, our study explored the use of sensitivity (i.e., d-prime (d’)) and response bias (i.e., criterion location (c)) in signal detection theory (SDT) as a measure of drivers’ ADAS mental models. Based on the data collected from a survey among 287 ADAS users, regression models were fitted, and it was found that d’ and c accounted for a large variance when estimating drivers’ ADAS mental models as measured by MMSs (adjusted R2 > 0.8). Further, predictors of MMSs were also predictors of d’ and c, but d’ and c include additional information that was not covered in MMSs. These findings support the usage of d’ and c as standard metrics for assessing drivers’ ADAS mental models in future research. © 2023 Human Factors and Ergonomics Society.

Attention Mechanism based Pipe Recognition Network with a Hybrid Dataset

IEEE Transactions on Automation Science and Engineering 2025年

A building information model for existing pipes is essential for maintenance tasks such as repairs, reconstruction, and modernization. However, current automatic recognition methods are not well-suited for handling complex piping systems on mobile devices. To address this, an attention mechanism-based recognition network is proposed. First, a decoder network is designed to minimize information loss during feature extraction. Its ability to integrate with various encoder networks allows for flexible network design tailored to different applications. Second, an extended convolution pyramid, tailored to the geometric characteristics of pipes, is introduced to enhance computational efficiency. The proposed network’s performance was evaluated through ablation studies and comparison experiments with state-of-the-art methods. To address the challenge of data scarcity, a hybrid dataset was developed using neural style transfer techniques, and an evaluation experiment demonstrated its effectiveness. © 2004-2012 IEEE.

The sensitivity (d’) and bias (c) in signal detection theory can reflect respondents’ objective performance in understanding a system and their bias towards saying yes. Thus, d’ and c can be used as alternatives of proportion correctness (PC) when evaluating drivers’ mental models of advanced driving assistance system (ADAS). The adoption of d’ and c as mental model metrics also allows cross-study comparisons as their values are independent of signal (i.e., ADAS function present) and noise (i.e., ADAS function absent) ratio. However, there is no closed-form solution of the relationships among d’, c, and PC. Hence, using numerical simulations, we extracted an empirical equation that quantifies how d’ and c can estimate PC. The equation was then validated based on participants’ responses from a survey study that targeted towards drivers’ ADAS mental model. The results show that the empirical equation reached a satisfying performance (R2 > 0.8) in estimating PC. © 2023 Human Factors and Ergonomics Society.
