Agriculture as one of the oldest industries, dating as far back as the nomadic age originally depended solely on human effort, then apprehended animal labour, and then came mechanical advances such as diesel/steam-engine tractors and mechanical tools with hydrostatic power which needed control. The answer to unresolved problems relies on more advances that necessitate the replacement of human intellect to meet the requirements for superior autonomy in more indefinite and unstructured environments. Promising disciplines in this framework include Mechatronics, Large-scale optimization and Complex system automation, and our focus is on the advancement of irrigation system. Some of the applications of mechatronics in agriculture and their processes are discussed to gain insight on the state of the art, advantages and weaknesses of several methods employed.

Some amount of backlash is often required in the assembly of gears but excess backlash can lead to increase vibration and wear of the gear assembly. Also, interference-risk profile can result in undercutting of gear tooth. This paper optimized a spur external involute-profile gear by developing an application for the modeling of its geometrical compatibility using Matlab®. The application uses existing models to test for interference and a proposed model to determine effective backlash in a gear. The backlash values resulting from the application are more confined and the model is applicable to a wider range of modules suggested by American Gear Manufacturers Association. Simulation of the ge...

Several literatures have reported the influence of process parameters such as raster angle and print speed on some mechanical properties of FDM-printed, PLA-prototypes used in other applications. This study investigated the effects of interior fill, top solid layer, and layer height on the compressive strength of rapid patterns for sand casting application. Different values of the process parameters were used to print the pre-defined samples of the PLA-specimens and a compression test was performed on them. The coupled effects of the process parameters on compressive strength were investigated and the optimum values were determined. Interior fill of 36%, layer height of 0.21 mm and top solid layer of 4 were found to produce a FDM-printed, PLApattern that sustained a compaction pressure...

To illustrate the concept and practical issues arising, a systems design approach is taken to identify some of the engineering requirements and, in the focus of this article, a prototype has been developed at Lancaster University. The robotic device is semi-humanoid in that the upper half features two 7-DOF manipulators, designed in part to resemble human operation, while the lower half consists of a fourwheeled base, prioritising ease of operation and reliability over the flexibility offered by a leg-based system.

This study aims to model and design a humanoid robot with additive manufacturing process. Computer aided design (CAD) models of the selected concepts were developed in Fusion360 and imported into SolidWorks to optimise and improve the design. The first stage of the design focused on the development of the main body and wheelbase, while the second phase focused on the arms and manipulators. To meet the project requirement of a payload of 500 g we selected a tough and low density material with appropriate servo motor with a torque of 9.4 kg/cm at each joint. The parts of the robot were produced by additive manufacturing process with an extrusion technique called fused deposition modelling (FDM) where a continuous filament of thermoplastic material, Polylactic acid (PLA) was fed from a coil via a moving heated extruder head and gradually deposit on the work. Overall, the robot proved that the proposed design is able to achieve the design requirements while mimicking basic human movements.

These aspirations and goals mirror the ambitions of Africans for flourishing and prosperity, for a continent of free nationals and extended horizons, for solidarity and integration coupled with freedom from conflict and enhanced human security. Although the timeline for achievement of these goals and aspirations grows shorter; there have been reports that the undergraduates' final year projects in most of Africa's universities are not proffering relevant solutions to different national problems. This paper studies completed final year projects of undergraduates in the Department of Mechanical Engineering in one of the toprated universities in Africa, over the period of seven sessions. The projects over these periods were classified using some parameters such as United Nation Development Agenda, Africa Union Agenda and Scopus Classification System for projects. A database of the classified projects was designed and developed; which was subsequently analyzed utilising the Statistical Analysis Software to determine different prescribed parameters. Based on the results, the field of Corrosion in the Department had the highest number of projects during this period.

Agriculture as one of the oldest industries, dating as far back as the nomadic age originally depended solely on human effort, then apprehended animal labour, and then came mechanical advances such as diesel/steam-engine tractors and mechanical tools with hydrostatic power which needed control. The answer to unresolved problems relies on more advances that necessitate the replacement of human intellect to meet the requirements for superior autonomy in more indefinite and unstructured environments. Promising disciplines in this framework include Mechatronics, Large-scale optimization and Complex system automation, and our focus is on the advancement of irrigation system. Some of the applications of mechatronics in agriculture and their processes are discussed to gain insight on the state of the art, advantages and weaknesses of several methods employed.
