“…Soft robots, characterized by low stiffness, lightweight, infinite degrees of freedom, and the ability to withstand high-energy impacts, possess many superior comprehensive performance features, such as good safety, high flexibility, and applicability in various scenarios [2]. So far, soft robots have become a research hotspot in the field of robotics and have been widely applied in areas such as biomimetic robots [3]- [8], healthcare [9]- [11], and industry [12]- [15], among other [16]- [21]. In recent years, scholars both domestically and internationally have conducted extensive research on various soft robots.…”

To optimize the performance of the soft actuator, numerical experiments and regression analysis of the multi-structure parameter are presented based on the numerical calculation method. Firstly, numerical experiments and regression analysis were performed on the parameters of different driving channel shapes, including equilateral triangle, square, regular pentagon, regular hexagon, and circle, to determine the driving performance under different channel cross-sections. Secondly, numerical experiments and regression analysis were conducted on the parameters of fiber winding diameter and winding angle of the soft actuator, and qualitative analysis was performed on the failure states of the numerical calculations. Lastly, numerical experiments and regression analysis were carried out on the parameters of wall thickness and driving channel length of the soft actuator to determine the influence of these parameters on the driving performance. Through the numerical experiments and regression analysis, this study provides a necessary theoretical foundation for the optimization design of soft actuator, effectively improving the development efficiency and dynamic performance of soft actuators.

“…To avoid material damage during the orientation adjustment, the traditional jaws with rigid structures should be avoided, and some existing flexible jaws also have disadvantages such as insufficient gripping force (SepúLveda et al, 2020) and poor wrapability (Li et al, 2022). An end‐effector with a pressure sensor was designed (Zhang et al, 2023) to limit the pressure magnitude.…”

Cracked carrots account for a large proportion of defective carrots, which are usually discarded or used as feed, resulting in resource waste and economic benefit loss. Cracked carrots can be used as raw materials for further processed carrot products after being trimmed. So, an auxiliary device was developed combining PLC (Programmable Logic Controller) and machine vision to achieve clamping and crack defect localization for intelligent trimming of crack defect. The carrot was orientated based on the area method, rotated by flexible jaws and a rotating cylinder to make the carrot head and tail aligned. The clamping device could non‐destructively clamp carrot in axial and radial direction with a force threshold of 10 and 22 N respectively, and rotate carrot to make the crack defect upwards. The results showed that the recognition accuracy of carrot head and tail orientation was 98%, the average deviation of carrot centroid clamping position was less than 9 mm at a speed of 300 mm/s, the rotational positioning time was less than 3 s and the number of adjustments were no more than 2 at a motor speed of 180 rpm, which could meet the subsequent trimming requirements.Practical applicationsTrimming the cracked area of carrots can reduce bacterial growth and decay, which is beneficial for subsequent processing and reduces resource waste. This article designs a carrot auxiliary trimming device, which uses image processing technology to recognize the orientation of the head and tail of carrots and the cracked area, and uses automated equipment to achieve stable clamping of carrots and make the cracked area face the trimming tool. This study is beneficial for the refined management of agricultural products.
