Considering, the previous work done by others in line with this study, the methodology used in carrying out this present work differs from the various methods used in related works in the literature ...
In recent times, the entire world has been in consistent search of cleaner and safer ways of generating and producing energy. Due to continuous industrialization in different parts of the world, there has been a huge deterioration in the natural state of the environment. This is reflective in different areas and the most prominent has to be Climate change. This paper therefore focuses on the exploitation of the abundant solar energy from the sun to drive a lawn mower. The designed solar powered lawn mower comprises of electric motor, a charge controller, battery (12V), Solar Panel (30W), rotational blade and a control switch. The entire operation frame work is achieved using the electric motor which is able to provide the necessary torque needed for the rotation of the blade which is mounted to the shaft of the motor. The solar powered lawn mower is operated by a switch on the board which closes the circuit and allows current flow to the motor and ultimately, causing the actuation of the blade. Under a very sunny condition battery charges and operates simultaneously, taking a longer time to discharge. Finally, the performance evaluation of the battery was carried out with the machine and it was found to have a theoretical efficiency of 85%.
... The choice of solar powered lawn mower was not limited to the reduction in carbon emissions but rather lower operational expenses of the machine due to the abundant energy from sunlight [6,7]. Solar powered lawn mower uses a photovoltaic panel to generate the energy required to propel the mower [8,9]. The solar panel installed on the mower frame collects sunlight and converts it into electrical energy that is used to drive the motor [10,11]. ...
Solar powered lawn mower has offered a more convenient way of trimming the lawn due to the advancement in its technology. As the world gradually moves towards green technology, research has geared towards making solar powered mover readily available, efficient, and economical. However, few reports were available on the effect of grass types on battery voltage drop. In this paper, solar powered lawn mower was structured into phases which include, power supply phase, Arduino phase, motor phase and integration of the components. The 550-motor was sufficient to produce the required torque needed to drive the solar panel mower. The average efficiency of the solar panel was found to be 93 %. The battery voltage drop was investigated upon cutting different types of grasses to determine the rate at which power is dissipated in the solar powered lawn mower. The voltage drop of 0.34 V was recorded when cutting stubborn grass while that of soft grass was found to be 0.17 V. Rain sensor was incorporated to provide the user with a notification via Buzzer whenever raindrops are detected.
... This study is important not only in terms of contributing to the maintenance of lawns, but also in the broader context of promoting environmentally friendly technologies. Solar energy research and IoT integration in lawn equipment has advanced future developments in the field, demonstrating the potential for an environmentally friendly alternative to modern technology [8][9][10][11]. ...
Manual grass cutting requires manpower, consumes time, and often results in uneven grass height. To overcome these challenges, there is a pressing need for a system capable of autonomously cutting grass without human intervention. This research introduces a grass-cutting robot equipped with a solar-charged battery and can be operated using an android phone. The proposed system offers a cost-effective solution compared to existing alternatives, showcasing robustness, durability, and low maintenance requirements. The utilization of solar energy for battery charging makes the system environment friendly and free from pollution. Subject Classification: 93-XX, 94-XX.
... The control of a lawnmower is mainly determined by the control of the lawnmower motor [6]. The capacity of the motor control system directly determines the efficiency of the lawnmower, the quality of operation, and the user experience [7]; therefore, the selection of the type of motor for the lawnmower as well as the selection of the corresponding control strategy are particularly important [8]. ...
In this paper, we describe a position sensorless vector control system for a permanent magnet synchronous motor (PMSM) for a lawnmower in order to solve the problems of inferior dynamic performance and insufficient load resistance in the control process of lawnmower motors. A speed–current double-closed-loop vector control strategy was adopted to control the motor speed; an extended Kalman filter (EKF) was constructed to track the motor rotor position. STM32F407 was selected as the main control chip to establish the hardware experimental platform, and the performance of the control system was evaluated. The experimental results demonstrate that the control system accurately regulates motor speed, has good dynamic response characteristics, and can maintain stability under various loads; therefore, it meets the performance requirements of lawnmower motors in practical operation.
