RF CONTROLLED LAWNMOWER

This project entitled “Remote Frequency Control Lawnmower” is fabricated to design a lawnmower that can be controlled by using remote frequency controller. This project is focusing on the problem most of lawnmower today operates manually where human needs to control the machine directly in grass cutting activities. This requires a lot of energy if the area was too wide. The available lawn mower today uses petrol to operate the engine, this can contribute air pollution. The Remote Frequency Lawnmower is a machine to make cutting grass process easier. The lawnmower's movement will be controlled using RF remote control, where the transmitter circuit will be placed at the remote control while the receiver circuit will be placed at the lawnmower. The signal will be transfer from the remote control to the lawnmower by the antenna (joystick) and the signal transfer is using radio frequency signal (RF). RF is quite effective in long distance and the components are cheap and easy to get in the market. In this project, transmitter and receiver circuit is built to control the movement of the lawn mower, motor, and the rotation of the blade. H-Bridge connection is used in the circuit to control the lawnmower's movement whether to be slow or fast. There are two types of motor used in this project and both of it is dc motor.
