Design of Some Aspects of an Instructional Mobile Robots Based on Material Handling to Enhance the Skills of Mechanical Students

Robots are becoming an indispensable part of our society and have a great potential for application in mechanical engineering and Science Technology Engineering Mathematics in general. Robots are also gradually being integrated into our society. Robotics remains an important sector also in a manufacturing sector, as most engineers engage in manufacturing robots that can perform specific task and give appropriate results for the task. In other words, the engineers attempt to fabricate robots with perfect accuracy or 0 percent margin of error which is quite practicable as the technology improves. The success of the World Robotics Competition focusing on manufacturing teaching modules, the planning of mechanical design, the control of system and mobility of the robots through microprocessor technology has attracted educationists and researchers.

Teaching and Learning Based Robots (TLBR) are learning concept where teachers or instructors bring the real-world cases into the workshop, laboratory or classroom and encourage students to connect between knowledge possessed by its application in everyday life. Motivated by the technological process, this study utilized 4-D models as research and development process to design some aspects of instructional mobile robots to enhance the skills of mechanical students. The Models include four phases: definition phase, design phase, develop phase and disseminate stage. The research was carried out using Applied Research Design Development (ARDD) with the aim of producing learning tool in the form of an instructional mobile robot modules and kit for the skill advancement of mechanical engineering and technology students. The material selection process is critical in selecting the right material for this frame. Wood, aluminum, or steel may be suitable materials for the robot frame, but Al 3003 aluminum alloy becomes the best choice for the required parameters. These materials have excellent mechanical properties such as high tensile strength, high strength-to-weight ratio, corrosion resistance, ductility, formability, recyclability, etc. For these reasons, Aluminum alloys have been used in most of the applications. The strength of aluminum frame is very high, the cost is very low, and it is relatively light in weight. The results reveal that the models contain detailed data showing the complete mechanics of the system. This is enough to provide good information about instructional robotics and devices as well as robotic system. The results further underscore the effectiveness of each component by isolating all the components and individually testing them rigorously before integration. When fully integrated, the isolation and testing of all individual signals proves beneficial. Finally, the results show that the developed instructional mobile robot was found valid and reliable.
