This article illustrates the relationship among technology inclusion, women, and likely perspectives in the developing countries. This study demonstrates how Robotics and Artificial Intelligence (AI) affects the opportunities for women’s in developing world. The condition of women in developing world such as in India or south Asian area are considered as working domestically and are under-represented in good or high-level positions. Women are disproportionately facing prejudice and underemployed in the workplace. This paper describes the estimation of the implication of AI can exacerbate the bad status of women in the develop countries. This study attempts the comparison of women status in the developed and developing countries. This article provides an outstanding study of the enhancement of gender inequality and feminism in the developing world with the fast technical advancement in our society and at workplace.

The demand for liquefied natural gas (LNG) ships is increasing for various reasons. Despite their enormous size, cargo holds inside freighters transporting LNG have traditionally been constructed by welding to high-quality standards for safety. This process traditionally relies on manual labor or semi-automatic moving devices. In this study, a methodology was designed for robot-based automated laser welding inside large LNG cargo holds. The developed approach offers a practical solution to challenging issues such as the corrugation of the membrane that forms the inner walls of LNG cargo holds and the inter-floor movement of robots. This study analyzes and restructures the work for laser welding using mobile robots inside LNG cargo holds composed of membranes. For realistic constraints, such as inter-floor movement of robots and high-quality welding of membrane corrugations, methods integrated with manual work have been proposed. Additionally, for the overall membrane laser welding of the LNG cargo hold space, an automated method using robots was suggested. The developed methodology has been realized as operational software for the movement of robots for laser welding in LNG cargo holds.

“…With the rapid development of robotics technology, the application of mobile robots has extended from indoor structured environments to unstructured operational settings [1]; typical applications include geological surveying, emergency rescue, military reconnaissance, and so on [2]. The increasing variability of external environments and the growing complexity of tasks pose higher demands on mobile robots [3]. On the one hand, robots operating in complex environments require high reliability and adaptability.…”

In this study, we address the trajectory tracking control problem of a hydraulic-driven skid-steer mobile robot. A hierarchical control strategy is proposed to simultaneously consider the robot’s position control and the velocity control of the hydraulic motors. At the upper level, a nonlinear model predictive control (NMPC) method is employed to control the position and heading of the mobile robot. The NMPC controller takes into account the robot’s physical constraints and generates the desired robot motion velocity. Then, to control the hydraulic drive system, a current–velocity mapping-based control method is introduced. By establishing the mapping relationship between the control current applied to the hydraulic motor and its corresponding output velocity, the dynamics of the hydraulic motors are characterized. Consequently, the lower-level controller can directly obtain the control signal for the hydraulic actuator through lookup mappings. Additionally, PID controllers are adopted to compensate for velocity tracking errors. The proposed hierarchical control strategy decouples the robot’s position control and the hydraulic system control, simplifying the overall controller design, leading to improved control performance. To validate the effectiveness of the proposed control strategy, several experiments were conducted on a hydraulic-driven skid-steer mobile robot, and the results demonstrate the effectiveness of the proposed approach.
