DESIGN AND FABRICATION OF AGRICULTURAL ROBOT FOR SEEDING AND WEEDING OPERATION

This project deals with design and fabrication of mobile robot for the application of seeding and weeding operation in agriculture. The proposed model is wheel based mobile robot. This prototype can navigate itself on any agricultural land and perform seeding operation simultaneously. Navigation and localization tasks are performed with the help of on board sensors viz. accelerometer and GPS controlled by an on board micro computer. Static obstacles are avoided with help of Ultrasonic sensors. The proposed robot is a micro planter whose primary task would be to sow seeds at prefixed seeding intervals and controlling weeds in the field. precision seed metering and sowing mechanism have been proposed along with use of on board sensors .Self awareness of robots position is determined by the global and local maps generated from GPS and on board vision system paired to a personal computer. A suspension system has been proposed to maintain the stability of vehicle and prevent it from toppling in motion.
