Project Summary

PROJECT SUMMARY:

Autonoumous Plant Watering Robot for indoor environment is the autonoumous robot that can waters the plant without human intervention. In thisproject, we will design a complete autonomous plant watering system that can map its environment through Rao Blackwellized Particle Filter (RBPF) SLAM, can localize itself in that map using Monte Carlo Localization (MCL), to monitor and watch potted plants and water them according to their need in an efficient and timely manner by incorporating an embedded system with various sensors without human intervention. Our proposed system can detect plants through an RFID tag attached to each plant, sense water requirements of plants using HSM-20g temperature and humidity sensor attached with robot body and soil moisture sensor attached with robotic hand and water them according to data gets from the sensor through water reservoir attached with the robot. For mobilization of the robot, we used the SLAM algorithm that allows the vehicle to generate a map of its environment and to localize itself in that environment using LIDAR.

Project Objectives

PROJECT OBJETIVES:

The  core objectives of the proposed project are:

• To design a SLAM-based real-time autonomous plant watering robot that can map and navigate through its environment.
• The robot should be able to detect different species of plants.
• The robot should be able to recognize plant species as well as their water requirement and pot height.
• The robot must be able to collect and monitor plant data (i.e., temperature, humidity, moisture).
• To design an onboard water reservoir, able to water plants on the go, based on the number of plants, their water requirements, and the size of the robot.
• To design a mechanism for automatic refilling of water reservoir.
• To design a mechanism for automatic recharging of robot
• To design a wireless communication system (IoT) that can transfer sensor data and robot stats to the user.

Project Implementation Method

METHODOLOGY:

LiDAR and ultrasonic sensors will be used to allow the robot to map and navigate through its environment. These sensors will provide data in the form of distance from the landmarks. The raw data from LiDAR will be sent to a Raspberry Pi 4, for processing and it will also has high level control of system, meanwhile an Arduino Mega 2560 will have the low level control of the system. Arduino Mega 2560 will communicate with Raspberry Pi 4 via USB connection; the same connection will provide power to Arduino Mega 2560 and peripherals attached to it. The robot will be a differential derive robot with wheels attached to motors and 2 wheels and free wheels. The motors will be driven by motor driver circuit controlled by Arduino Mega 2560 Radio frequency identification will be utilized to detect and differentiate plants. A closed loop PID control for motors attached to the robot will be implemented using Arduino Mega 2560. Built-in encoders of DC motors will be used to provide feedback in control system for motors. Plant detection will be done through a RFID ta attached to the pot. Plant specifications i.e. specie, water requirement, serial number, pot height and when was plant watered last time, will also be stored in RFID tag assigned to plant. To read data from and write data to RFID tag a RFID reader/writer module will be used which will be connected to Arduino Mega 2560. For the real time collection of data, temperature and relative humidity sensors fixed on robot and soil moisture sensor attached to a robotic arm will be utilized. The raw input from these sensors, which will be in analog form, will be given to the built-in ADC of Arduino Mega 2560. This data extracted from the inputs of sensors will be displayed on an Alphanumeric LCD attached to Arduino Mega 2560. The robot will a have an onboard water reservoir for watering plants, a relay controlled by Arduino Mega 2560 will trigger an electrical pump attached to water reservoir for watering plants. A height sensor will continuously monitor the water level and if water level falls below a set threshold value that, sensor will inform the robot that it requires refilling, the robot will stop its current operation of move to base station where a wirelessly controlled solenoid valve will allow automatic refiling of reservoir. Auto recharging of robot will be achieved by employing wireless charging coils or by incorporating solar panels. An IoT network will established for storing and transmitting robot stats and sensor data to a web server and IoT application.

Technical Details of Final Deliverable

FINAL DELIVERABLE:

The  final deliverable outcome of this project will be a reliable solution for watering neds of plants in the form of a completely autonomus robot. The robot will be an integration of both hardware and software systems. Autonomous plant watering robot using SLAM will have many advantages on other techniques to design a robot.
