IoT Dog Daycare Robot

This guide will help you create an IoT-enabled Dog Daycare Robot that can monitor, entertain, and interact with dogs in a daycare setting. The robot will feature various sensors and actuators to ensure a safe and engaging environment for the dogs.

Components Required

• Arduino or Raspberry Pi (for the main controller)
• Camera module (for monitoring and interaction)
• Microphone (for detecting barking or sounds)
• Speakers (for audio output and commands)
• Motors and wheels (for movement)
• Ultrasonic sensors (for obstacle detection and distance measurement)
• Wi-Fi module (e.g., ESP8266 or similar, for IoT connectivity)
• Battery pack (for powering the robot)
• Power management circuitry
• Various connectors and wires

Setting Up the Hardware

Follow these steps to set up the hardware:

1. Assemble the Robot Frame

   Build or acquire a frame for the robot that can house all the components. Ensure it is sturdy and capable of supporting the motors and sensors.

2. Install Motors and Wheels

   Attach the motors and wheels to the robot frame. The motors will control the movement of the robot, while the wheels will provide mobility.

3. Connect Sensors and Modules

   Wire the ultrasonic sensors, camera module, microphone, and speakers to the Arduino or Raspberry Pi. Ensure proper connections for power and data communication.

4. Integrate the Wi-Fi Module

   Connect the Wi-Fi module to the main controller to enable IoT connectivity. This will allow remote control and monitoring via a web interface or mobile app.

5. Power the Robot

   Install the battery pack and power management circuitry. Ensure the robot has a reliable power source to operate all components effectively.

Programming the Robot

Write code for the robot to handle movement, sensor data processing, and IoT communication. Here’s a basic outline of the code:

                #include <Wire.h>
                #include <ESP8266WiFi.h>
                #include <Servo.h>

                #define MOTOR_PIN1 9
                #define MOTOR_PIN2 10
                #define ULTRASONIC_TRIG_PIN 12
                #define ULTRASONIC_ECHO_PIN 13

                const char* ssid = "your_wifi_ssid";
                const char* password = "your_wifi_password";

                WiFiClient client;

                void setup() {
                    Serial.begin(9600);
                    pinMode(MOTOR_PIN1, OUTPUT);
                    pinMode(MOTOR_PIN2, OUTPUT);
                    pinMode(ULTRASONIC_TRIG_PIN, OUTPUT);
                    pinMode(ULTRASONIC_ECHO_PIN, INPUT);
                    connectToWiFi();
                }

                void loop() {
                    long duration;
                    int distance;
                    
                    // Ultrasonic sensor code
                    digitalWrite(ULTRASONIC_TRIG_PIN, LOW);
                    delayMicroseconds(2);
                    digitalWrite(ULTRASONIC_TRIG_PIN, HIGH);
                    delayMicroseconds(10);
                    digitalWrite(ULTRASONIC_TRIG_PIN, LOW);
                    duration = pulseIn(ULTRASONIC_ECHO_PIN, HIGH);
                    distance = duration * 0.034 / 2;
                    
                    if (distance < 20) {
                        // Move backward
                        digitalWrite(MOTOR_PIN1, LOW);
                        digitalWrite(MOTOR_PIN2, HIGH);
                    } else {
                        // Move forward
                        digitalWrite(MOTOR_PIN1, HIGH);
                        digitalWrite(MOTOR_PIN2, LOW);
                    }
                    
                    delay(1000); // Delay between readings
                }

                void connectToWiFi() {
                    WiFi.begin(ssid, password);
                    while (WiFi.status() != WL_CONNECTED) {
                        delay(500);
                        Serial.print(".");
                    }
                    Serial.println("Connected to WiFi");
                }
            

This code controls the robot’s movement based on distance measurements from the ultrasonic sensor and handles Wi-Fi connectivity for IoT functions.

Implementing Features

Enhance the robot with additional features:

1. Camera Integration

   Use the camera module to stream live video or capture images. This can be achieved using the MJPEG streaming library or similar for the Arduino or Raspberry Pi.

2. Audio Commands

   Implement audio commands and playback using the speakers. You can program predefined sounds or messages to interact with the dogs.

3. Remote Control

   Develop a web interface or mobile app to control the robot remotely. This can include features like manual movement control, camera viewing, and triggering audio commands.
