Cost effective autonomous plant watering robot

Abstract

This paper presents a solution to those who forget to water the indoor potted plants because of the busy schedule. It presents a system that is fully autonomous and cost-effective. This autonomous system consists of a mobile robot with RFID detector and a temperature-humidity sensor and uses wireless communication between the mobile robot and sensing module. Thisautonomous system is adaptive to any kind of weather condition and addresses the watering needs of the plants with the help of temperature-humidity sensor. The gardening robot used is portable and contains an RFID module, Controller, awater reservoir and a water pump. Without human intervention thisautonomousrobot can sense the watering need of a plantlocatesthe plant following a predefined path and then waters the plant.An RFID tag attached to the potted plant helps for identification. In addition this paper describes the implementation of the system in detail along with the complete circuitry. The paper is concluded with the analysis of water carrying capacity and time needed to water a set of potted plants.
