this project deals with the development of a solar powered ploughing robot. the device is an autonomous mobile robot powered by solar power. solar energy in the konkan region is available for 8-9 months in a year with the average sunshine hours ranging from 7-8 hours per day. this device effectively utilizes the available solar energy for generation of power for ploughing small fields. farmers who own these small fields/lands constitute 70% of the agriculture sector. the device reduces the dependency of farmers on diesel powered vehicles and animals. it also aids to reduce human effort for the ploughing process. this method not only saves electricity but also reduces air pollution by preventing the emission of toxic gases into the atmosphere. it eliminates the use of bulls and human labour. it also reduces the time taken to plough the fields. the solar panel converts light radiations into useful electricity, which is stored in a battery. a cast iron plough is mounted on a fiber reinforced plastic (frp) body. the motion of the robot is controlled by atmega32 microcontroller which is aided by using 2 infra-red proximity sensors for obstacle detection. solar powered ploughing robot (sppr) utilizes a 14 w capacity solar panel to convert the light energy into electricity. the overall current produced by the panel is transmitted to four 6v batteries. the batteries drive four dc motors for vehicle movement and one motor for ploughing. a two way 12 v charge controller which has three terminals is used to make or break the connection in the circuit. this switch serves two functions, it establishes a connection between the panel and the battery which indicates the charging of the battery and it also establishes the connection between the battery and the plough which indicates the discharging of battery. the function of the plough is to remove soil from the field. a moisture sensor is used to detect the moisture level of the field.
