Growth of unwanted plants in small farms which effects the growth and even health of other plants growth in that farm. When the saplings are planted even more care is needed regarding moisture of the soil. To solve the above problems, we are using a four -wheeled bot that detect the weeds and cut them with a blade attached at the base of the robot and the blade is given a external power source. The moisture content in the soil is checked with the help of a moisture sensor and maintains the optimum moisture levels in required ratios. The sprinkler is a pipe with the holes so when the moisture levels are less than required then the pipe holes will be opened and the water will get to the main plant and moisture levels are increased . The normal plants have rings around them so when the robot comes towards the plants turns its path.
