Solar Powered Automated Grass Cutting Machine
Project Area of Specialization Internet of ThingsProject SummaryConventional grass cutters have been widely used recently by workers in the gardening and agricultural industries. However, in Pakistan, manual-handled grass cutters consume a lot of energy and produce air pollution, directly affecting the workers’ health. The conventional methods for grass cutting cause a lot of issues such as high levels of noise and vibration which can cause serious health issues such as grip strength, decreased hand sensation, and dexterity, finger blanching, or ‘white fingers’ and carpal tunnel. In order to address these issues, a new design of a grass-cutting machine has been proposed. This device can be fueled by solar energy and smartly controlled, which has been named a Solar Powered Automated Grass Cutting Machine. The system uses a 12V, - 100AH battery to power a 12V DC motor of 180W. A solar panel 1 000V system voltage is used to charge the battery. A solar charge controller of 20A is used to control the energy in the battery. The machine uses a sheet metal blade to cut the grass. It can run for almost two hours when fully charged and there is no sun. It is easy to tell if the battery is fully charged or flat.
Project ObjectivesThe following are the objectives of this project
· To design a lawnmower operating on solar energy.
· To reduce operating costs.
· To avoid any damage to the operator and the lawnmower itself.
· To keep the environment clean and healthy and protect the environment.
. To reduce human efforts.
· To cut various types of grasses with precision.
• To encourage people to convert from the normal way of using oil and energy sources such as clean and green environmentally friendly energy sources..
• To design such a system that can give maximum reliability and efficiency with a low budget.
• To ensure that system will run for many years without failure advanced features such as over under charge for battery short circuit protection, the overload will be added to ensure safe operation with maximum reliability for the system.
Automated solar grass cutting machine is a fully automated grass cutting robotic vehicle powered by solar energy that also avoids obstacles and is capable of fully automated grass cutting, without the need of any human interaction. The system uses 12V batteries to power the vehicle movement motors as well as the grass cutter motor. We also use a solar panel to charge the battery so that there is no need of charging it externally. The grass cutting machine and vehicle motors are interfaced to a microcontroller that controls the working of all the motors. The microcontroller moves the vehicle motors in a forward direction in case no obstacle is detected. On obstacle detection, IR sensor monitors it and the microcontroller thus stops the grass cuter motor so as to avoid any damage to the object/human/animal. The microcontroller then turns the vehicle until it gets clear of the object and then moves the grass cutting machine in the forwarding direction again.
Benefits of the Project- It can preserve the nonrenewable sources of energy such as petrol, and gasoline that is in shortage in Pakistan already.
- This automatic machine can also decrease the choice of forms of pollution such as air pollution and noise pollution.
- Electricity is saved as we utilize solar energy which is a renewable source of energy.
- The simulation which is designed using profuse is almost clear the concept of robot and this is very helpful for designing hardware of solar-powered autonomous grass cutting machine.
- Many types of sensors can be added to the Robot in order to make the Robot extremely easy to use. The size of the solar panel and battery can be increased as per our requirements to increase the operating time to a greater extent.
The design contains ultrasonic sensor, DC motor, node MCU, Arduino, and IR sensors and a 12 voltage battery for the entire circuit and another 12v volts for the cutting blade all these together combined we get a grass cutting robot/machine. Arduino is the brain of the overall system. Arduino is a single-board microcontroller intended to make building interactive objects or environments more accessible and ultrasonic sensors are used to detect if the robot was heading into an object. Safety is the main concern when designing a robot with blades. The microprocessor must be in the robot to protect it from the natural elements. Ultrasonic sensors will be mounted directly in front of the robot for maximum detection. The microcontroller takes the input from the ultrasonic sensors when any interrupt or obstacle occurs the ultrasonic sensor senses the obstacle and gives feedback to the microcontroller then according to the program which was given to the microcontroller it turns left or right. It waits up to some delay and senses again and the same procedure works. if no detection occurs to ultrasonic range then it moves forward until it finds some detection. Batteries are used for power generation for the robot movement and the battery is rechargeable. Node MCU is used as a Wi-Fi model to connect the system to the internet.
