Study on Automated Solar Grass Cutter Shyam Lal Sharma Department of Mechanical Engineering Noida Institute of Engineering & Technology, Greater Noida, UP
Abstract Automated Solar Grass Cutter is a fully automated grass cutting robotic mover powered by solar energy with solar penal that also avoids obstacles and is capable of fully automated grass cutting without the need of any human interaction. The system uses 10V batteries to power the mover 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 cutter motors are interfaced to an 8051 micro-controller that controls the working of all the motors. It is also interfaced to an ultrasonic sensor for object detection. The micro-controller moves the mover motors in forward direction in case no obstacle is detected. On obstacle detection the ultrasonic sensor monitors it and the micro-controller thus stops the grass cuter motor to avoid any damage to the object/human/animal whatever it is. Micro-controller then turns the robotic as long as it gets clear of the object and then moves the grass cutter in forward direction again. Keywords- Automated Solar Grass Cutter, Solar Penal, Mover Movement Motors, Grass Cutter Motor, Micro-controller & Ultrasonic Sensor
I. INTRODUCTION The first Grass Cutter was invented by Edwin Budding in 1830, just outside Stroud, in Gloucestershire, England. Budding’s Cutter designed primarily to cut the grass on sports grounds was and extensive gardens, as a superior alternative to the scythe, and was granted a British patent on August 31, 1830. In 1995, the first fully solar powered robotic mower became available. The Grass Cutter is an aid in the mundane task of grass cutting and tending to lawns. Due to the revolution of green movement in the present scenario the industries with major campus areas are changing the percentage of greenery in the campuses and increased greenery causes increased effort and money to tend to. In such cases the lawn mower proves to be a god sent. Due to increased availability of system on chips, the lawn mower can be automated very easily and also the reduced size and cost of Dc motors causes the system to be independent of fossil fuels to be able to tap into renewable energies. The presence of Ultrasonic sensors and light dependent resistors in a smaller and cheaper packaging cause to be more aware of its surroundings. Traditional design of Grass Cutter had motored powered engines which required regular maintenance such as engine oil and greasing. They also created a lot of noise pollution and air pollution. In the cold and harsh environment the fossil fuel powered motors tend to freeze and not run. These problems are solved by using electric motors. They are also much greener because they use solar panel. The mover uses battery chorded system causes a range as limitation and damage to the chords.
II. LITERATURE SURVEY 1) E. Naresh (2016) provide switch between the mechanical circuit breaker. It starts and stops the working of the motor. From this motor, power transmits to the mechanism and this makes the blade to rotate on the shaft this makes to cut the grass. 2) Vicky Jain (2016) have prepared wireless grass cutter. They have used solar panel so it is not required to charge battery externally and battery is continuously charged at constant voltage when grass cutter is in working. The battery is getting charged by using day light and we can use it as per our convenience ,Because of two DC motor both forward and backward motion of grass cutter can simultaneously possible. 3) Prabhat Kumar (2015) explained that solar plate which is placed above the grass cutter generates solar energy and use this energy for working the grass cutter. Also, using driver circuit for controlling speed of motor as per the requirement. For preventing battery from overcharging and over discharging regulator is placed into the system and it should be placed in series. They have provided LCD display unit which displays voltage generated during solar rays trapping. Due to seasonal conditions if battery is not charged they can provide the power bank to charge the battery instantly. 4) Praful Ulhe (2016) prepared manually operated grass cutter with spiral roller blades due to spiral blades increases the efficiency of cutting. For adjusting the height reel cutter is component placed on grass cutter. The battery can be charged during working conditions and it also having AC charging. For collection of cut grass a box is placed over grass cutter so the cut grass put outside the lawn. It is having light in weight and compact in design. 5) Vicky Jain (2016) et. al. They have prepared wireless grass cutter. There are two main components such as transmitter and receiver. Transmitter continuously transmits the rays if any obstacle come in front of grass cutter then the rays are reflected back towards the receiver. The receiver receive the signals in the serial form encoder but microcontroller required parallel data for communication so receiver sends data to decoder to convert data in the parallel form and then it passed to microcontroller.
