The actuator, serving as the fundamental power source of a soft robot, functions as its central component. The field of soft robotics has garnered increasing research attention since its inception. Pneumatic crawling robots, being an essential branch within the realm of soft robotics, possess notable characteristics such as rapid response time, cost-effectiveness, and human-computer interaction safety. Consequently, they hold significant research value. Among various types of crawling robots that have garnered considerable interest from researchers is the inchworm crawling robot. This paper aims to address the design and development aspects pertaining to inchworm actuators. By utilizing ABAQUS simulation software and taking displacement as the reference parameter, an analysis was conducted to investigate the impact of various geometric parameters on actuator displacement. Additionally, optimization of these geometric parameters was performed. The values of aspect ratio, length-to-width ratio, vertex angle and gap depth suitable for inchworm-like actuator are obtained. These findings are presented for the first time in the field of crawling soft robots and provide a theoretical basis for the development of pneumatic inchworm-like actuators. © 2024 IEEE.

The resilient H∞ state estimation problem is investigated in this paper for a kind of neural networks with random parameters and time delays based on a dynamic event-triggered mechanism, which is employed for the purpose of reducing energy consumption. Under the action of the dynamic event-triggered mechanism, the measurement output is transmitted to the corresponding state estimator only when a certain triggering condition is met. The aim of this paper is to design a resilient state estimator for the delayed neural networks with random parameters such that the dynamics of estimation error system is asymptotically mean-square stable with the specified H∞ performance requirement. We derive a sufficient condition by using the Lyapunov theory, which guarantees that the estimation error system is asymptotically mean-the given H∞ performance constraint. Then, the gain matrix of the designed state estimator is presented by means of solving a set of linear matrix inequalities. A numerical example is provided to demonstrate the effectiveness of the designed state estimator. © 2023 IEEE.

Accurate fault diagnosis plays a key role in the safe and efficient operation of electrical motors. Aiming at multi-class motor fault diagnosis under complex working conditions, a signal fusion-based fault diagnosis framework is proposed. Measurement parameters from different sensors are first transformed by wavelet denoising and fast Fourier transform (FFT). Then, multiple parameters spectrum and working condition information are integrated and converted into high-dimension matrices. Finally, a channel-attention-based convolution neural network (CA-CNN) is proposed to extract fault patterns from a reconstructed matrix and output diagnosis results. Experiment results on both simulated and experimental datasets verify the effectiveness of the proposed method. © 2024 IEEE.
