The main function of this robot is to remove the unwanted tiny plants or grass from the main crop, this system is very useful for farmer which avoids lot of manual work. Plucking weeds manually is very painful activity and also consumes lot of time and therefore this mechanism is designed. Since it is a prototype module, basic version of grass or tiny weeds plucking mechanism is designed with spur gears. The moving mechanism is constructed with motorized wheels, for this purpose 30RPM motors are used. The mechanism is designed to move in all directions including reverse direction. The plucking mechanism designed with spur gears is attached with another motor shaft. Two spur gears are used and are meshed with each other, when the vehicle is moving and when the gears are rolling, the grass or tiny weeds will be removed by the gear mechanism. The demo module is constructed with small spur gears, with this the basic concept can be proved and it is not a full fledged mechanism. With the help of a remote control unit constructed with 12E, 12D chips & RF transmitter, entire machine can be controlled. H Bridge IC is used to drive the wheel drive motors through remote and weed picking mechanism must be activated manually through third DC motor. Moving mechanism is controlled through 2 DC motors and is controlled independently by which mechanism will be moved in all directions. 12V, 1Ah Rechargeable battery is used to run the entire system and this battery can be charged through ac adapter. The remote is constructed using four keys to move the robot forward, reverse, right and left directions. By pressing any control key in the remote unit, the encoder chip generates proportionate digital code, which is fed to the RF transmitter for transmitting the data. In the receiver, the received data will be decoded by the 12D IC and based on this code this chip enables the H Bridge IC by which the corresponding motor rotates in one direction. Likewise both DC motors will be controlled independently according to the command code received by the communication system.
