Abstract
The concept presented here is innovative & introduced in the field of agriculture. 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 former 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 89C2051 Microcontroller chip & RF transmitter, entire machine can be controlled. The main processing unit arranged over the moving mechanism is also constructed with same controller chip. Relay is used to energize the spur gear mechanism and H Bridge IC is used to drive the wheel drive motors. Here both motors are controlled independently by which mechanism will be moved in all directions. Entire system is designed to utilize free power source of solar energy, for this purpose, 12V – 0.8 Amps panel is used and it is arranged over the top of mechanical structure. The output of the panel is used to charge the battery and here 12v, 2Ah battery is used.
