Robot is a system that contains sensors, control systems, manipulators, power supplies and software all working together to perform a task. Designing, building, programming and testing a robot is a combination of physics, mechanical engineering, electrical engineering, structural engineering, mathematics and computing .
Joystick Shield is interfaced with Arduino Uno board. The user can control robot movements such as forward, backward, left, right, stop etc. The zigbee module transmits commands to robot. The ATMEGA328 microcontroller processes data and controls robot movements through L293d motor driver circuit. The dc motors are interfaced with the L293d circuit. The temperature and humidity sensor DHT11 is interfaced with controller. The soil moisture senses soil status whether it is dry or wet. We can control water sprinkler motor though current driver ULN2003. The sensor status is displayed on 20×4 LCD.
