Summary: Silane-modified AlN nanoparticles are composited with SMPI matrix resin to prepare fast-response high-Tg shape memory composites. Micro-nano synergistic thermal conduction networks are constructed using nano-sized AlN and micron-sized Al2O3, where AlN acts as the thermal conduction island and Al2O3 acts as the thermal conduction bridge. The resulting material shows significant improvements in thermal conductivity and shape recovery speed, making it suitable for high temperature active deformation structures.

Summary: To understand neural activity and behavior, recording multi-neuronal activity in freely behaving animals is desired but challenging. In this study, a new tracking microscope using acousto-optic deflectors (AODs) and an acoustic GRIN lens (TAG lens) was demonstrated to achieve high-speed 2D scanning and recording of neural activity in moving larval Drosophila. This technique can be applied to existing two-photon microscopes for 3D tracking.

Summary: This paper introduces an approach to address the problem of inaccessible inner controllers in industrial robots using an adaptive radial basis function neural network outer controller. By approximating the dynamics of the inner controller and utilizing the inherent property of RBF NN to reduce adaptive parameters, the influence of the inner controller on the closed-loop system is eliminated. The effectiveness of the proposed approach is verified through simulation and experimental studies.

Summary: This paper investigates the bodily synchronization between humans and robots in Human Robot Interaction (HRI). The study explores unintentional rhythmic entrainment and synchronization in HRI and compares the stability of coordination under different conditions. The findings suggest that unintentional entrainment is present in HRI, bi-directional coupling produces more stable coordination, and intentional coordination is more stable than unintentional coordination. The study provides a foundation for modeling future social robots involving unintentional and bidirectional synchronization.

Summary: This paper introduces a novel passively articulated tracked robot called Polibot, which shows excellent performance in soft-terrain applications by providing better traction than wheels or legs. The robot features a rubber track wrapped around four independently suspended road wheels, an idler wheel, and the sprocket on each side, and it can adapt to various terrains. An inverse kinematic model is developed to predict the system configuration based on constraint equations and quasi-static force analysis, which is validated against the real prototype with good agreement. The model can also be used to evaluate the influence of suspension design parameters and operating conditions, providing a useful tool for the proper setup of the robot.
