Abstract: The extraordinary swimming capacity of fish in nature makes them unique among Allah's creations. It is extremely difficult for a robotic system to achieve fish-like swimming behaviors, especially in terms of swimming performance. Many fish use their pectoral fins to provide thrust over a wide speed range and to carry out tricky maneuvers. In this paper, we report a robotic fish that can travel forward and backward using its propulsion system. In this report, the creation of a conceptual design for an interactive fish robot took into account a number of factors, including swimming ability, leakage testing, and motion controller. This needed considerable mechanical design work, and the result is a quick-return mechanism for the fish's body. We made the decision to divide the body into the head, body, and tail. In order to create the propulsion system, we employed five servo motors. Finally, controlling the robot's motion is absolutely essential, especially if there is an obstruction in its path. The servo controller, which is located at the fish's head, serves as the primary controller for all of the motors and sensors.

Abstract: The emerging technologies presented by the fourth industrial revolution present new opportunities across the entire industrial sector. Among those paradigms that have seen rapid and significant growth in recent years are Virtual Reality (VR) and Augmented Reality (AR), collectively known as Extended Reality (XR). These technologies provide a wide range of unexplored solutions across the manufacturing industry, that promise to improve the effectiveness and speed of various existing processes. One such activity that could potentially stand to benefit from XR is the project and development of End of Arm Tooling (EOAT) for robot applications.The initial purpose of this work is to first study the XR technologies, their current applications across various industries, and the hardware and software involved in their use and development. Then, the main goal is to develop XR solutions to aid in the project, development, and assembly of EOAT systems for extracting injected parts from a mould. Checking in with industry professionals throughout the development of a VR application, the functionalities were tailored to their needs.

Abstract: Soft robotics presents itself as a new path to adopt in several applications in the industry. The area of soft robotics aims to equip robots for unpredictable needs, providing them with capabilities that are based not on control systems, but on the properties of materials and the morphology of their bodies. This work aims the creation of a soft robotics application, more specifically a soft gripper. The development of an original concept of a soft material handler (soft gripper) is intended, capable of performing the stipulated handling functions, through certain actuation mechanisms, meeting the requirements and constraints presented in the next sub-section. The final solution is based on an improvement procedure supported on structural Finite Element (FE) analyses. Cost analysis and prototype construction/validation finalize the evaluation. The gripper was designed, a prototype was executed, and tests were carried out to prove correct operation. These tests were successful showing the project as suitable for a real production environment.

Abstract: This paper presents a complete case study for designing and manufacturing chain parts for scraper chain conveyor (SCC) for a real client (chicken’s dietary supplements company). The chain of the SCC is dilapidated due to joints and pins deterioration. The Productivity was reduced as a result of operating at low capacity load and repeated maintenance. The condition of chain was too worse and not able to be repaired. Furthermore, the chain was non-standardized. Therefore, a complete design is required to replace the damage parts of the chain. The design procedures are: (1) calculation of the expected loads that exert on the chain during operation, (2) selection of materials, (3) designing the different parts of the chain taking into account safety, assembly process and economic considerations. The final design was justified and validated. The SCC is working properly and safety under various load capacities.

Abstract: Ceramic balls are great application in high precision components such as hybrid bearings or hip prostheses where high performance is only achieved through close tolerances of form and dimension. Green machining is a critical step in the manufacturing of balls since the allowance removed and the surface finish achieved at the conclusion have a direct influence on the quality of the final product. The work aims to design a prototype for machining the green ball to Ø19 mm following the approach of mechanical design methodology. The concept consists of three wheels, two for drag with speed and direction of rotation variables to promote random orbital effect on the ball and a grinding wheel with track of silicon carbide #120 mesh. Spherical zirconia blanks were shaped by isostatic pressing at 200 MPa and machined in the manufactured prototype.

Abstract: An improved grey wolf optimization (IGWO) algorithm is proposed for solving constrained mechanical design problems in this paper. In proposed IGWO algorithm, a novel nonlinearly update equation of convergence factor based on sines function is presented to balance the exploration ability and exploitation ability. The feasibility-based rules based on tournament selection was introduced to handle constrains. Simulation results and comparisons with other state-of-the-art algorithms using three constrained mechanical design problems are provided.

Abstract: In this paper, a mechanical design oriented Python program development system was created to assist engineers to manage their programming assets more efficiently. This cloud-based platform includes a content management system and Python-in-browser IDE (Integrated Development Environment). The motivation of this research is to allow mechanical designers to store their programs and design data locally and remotely in synchronous. This paper introduces the basic concept of the platform, architecture, installation and utilization, and the advantages that can be achieved by using this platform. This platform is released under the GPL V3 license.
