Summary: In this paper, a fault-tolerant control scheme is presented for a bio-inspired underwater robot with four flexible fins. The scheme re-configures the force allocation matrix depending on the faulty fin actuator, allowing decoupling of the 6-DOF controllable underwater vehicle using the remaining three fins. Experimental results demonstrate that the combination of a sliding mode controller with the proposed fault-tolerant control allocation approach ensures efficient trajectory tracking control performance when faults occur.

Summary: This study investigates the controlled non-localized brittle fracture of a periodic beam-lattice under tensile loading. It is found that the lattice material exhibits a partially broken but not failed paradigm, which allows for energy absorption while maintaining structural integrity. Comparing different lattice configurations, an anisotropic lattice with triangular cells and a bone-microstructure inspired lattice with rectangular cells are found to have better energy absorption properties.

Summary: A bio-inspired nanocomposite is designed and fabricated with common microstructural features inspired by bones to overcome the trade-off between stiffness and damping. The role of these features on damping is investigated through experimental and theoretical research. The inclusion of intramolecular dangling chains improves damping, while the high modulus of multi-walled carbon nanotubes (MWCNTs) enhances the overall stiffness and induces an inelastic strain process at the interface to dissipate mechanical energy. The synergistic enhancement mechanism between the dangling chains and the moduli-mismatching interface leads to remarkably stiff yet lossy performances.

Summary: This study proposes a high-performance droplet-based nanogenerator based on solid-liquid contact electrification, which utilizes both displacement current and conduction current as the driving forces to output high-voltage direct current without a rectifier. It successfully realizes voltage-controlled electric shock process and demonstrates unparalleled capability for harvesting high-entropy water energy. This new device provides new insights into energy harvesting from solid-liquid interfaces and offers a compact, efficient, and cost-effective energy collection system.

Summary: Memory and learning are essential for problem-solving and survival. Episodic memory, a type of memory that allows us to re-experience events in our lives, is desired in systems that aim to replicate human-like behavior. However, current proposals often overlook neuroscientific evidence regarding memory dynamics. We propose a bio-inspired cognitive architecture for episodic memory and validate its capabilities through experiments.

Summary: Nonlinear structure design is crucial for the development of vibration isolation, energy harvesting, and fault diagnosis technologies. It is an effective means to enhance the performance of engineering structures. This study proposes a bio-inspired nonlinear oscillator and explores the benefits of nonlinear degradation in engineering applications. The degradation of the oscillator leads to the emergence of the degradation bistable oscillator and high-order quasi-zero stiffness oscillator. The analysis shows that nonlinear degradation can reduce unstable solutions and resonant frequency, allowing for large-amplitude inter-well motion at ultra-low frequency or low random excitation intensity. The study also presents vibration isolation and energy harvesting methods based on the nonlinear degradation mechanism and analyzes the performance of the oscillator under harmonic and stochastic excitations. Furthermore, the stochastic resonance of the degradation bistable oscillator can significantly improve the signal-to-noise ratio and enable early fault diagnosis. The findings deepen the understanding of nonlinear degenerate systems and provide new technical approaches for engineering applications.
