Abstract

The Bonic Bot S1 project aims to design and develop a multifunctional mobile robot equipped with articulated arms, capable of performing a variety of tasks in diverse environments. This robot integrates advanced sensors and actuators to enable smooth movement and precise manipulation of objects. Its mobility is enhanced by a robust wheeled or tracked base, allowing it to navigate different terrains effortlessly. The articulated arms mimic human-like movements, providing the robot with the ability to grasp, lift, and interact with its surroundings effectively. Additionally, the robot incorporates a user-friendly interface for remote control and programming, making it suitable for applications in industries such as logistics, healthcare, and education. Through this project, we aim to explore the potential of robotics in enhancing productivity and efficiency in everyday tasks.

Development Guide

Step 1: Setting Up the Hardware

1. Assemble the Base : Start by assembling the wheeled or tracked base of the robot. Ensure that the motors are securely attached and connected to the motor driver module.
2. Install the Articulated Arms : Attach the articulated arms to the main body of the robot. Use servo motors for the joints to allow for precise movement.
3. Connect the Power Supply : Integrate the rechargeable LiPo battery to power the robot. Ensure that the battery is securely mounted and connected to the power distribution board.
4. Integrate Sensors : Install the advanced sensors for obstacle detection. Connect them to the Arduino board for processing.

Step 2: Programming the Control System

1. Set Up the Arduino Environment : Install the Arduino IDE and set up the necessary libraries for motor control and sensor integration.
2. Write the Basic Movement Code : Create a basic sketch to control the movement of the robot. This includes forward, backward, left, and right movements.

   cpp
   DownloadCopy code
   #include <AFMotor.h>
   
   AF_DCMotor motor1(1); // Motor 1
   AF_DCMotor motor2(2); // Motor 2
   
   void setup() {
       motor1.setSpeed(200); // Set speed to 200
       motor2.setSpeed(200);
   }
   
   void loop() {
       motor1.forward(); // Move forward
       motor2.forward();
       delay(1000); // Move for 1 second
       motor1.stop(); // Stop
       motor2.stop();
   }
   

Step 3: Implementing Sensor Feedback

1. Integrate Sensor Code : Write code to read data from the sensors and make decisions based on that data.

   cpp
   DownloadCopy code
   const int sensorPin = A0; // Example sensor pin
   int sensorValue;
   
   void loop() {
       sensorValue = analogRead(sensorPin); // Read sensor value
       if (sensorValue < threshold) {
           // Obstacle detected
           motor1.stop();
           motor2.stop();
       }
   }
   

Step 4: Programming the Articulated Arms

1. Control the Servo Motors : Write code to control the servo motors for the articulated arms.

   cpp
   DownloadCopy code
   #include <Servo.h>
   
   Servo armServo1; // Create servo object for arm joint 1
   Servo armServo2; // Create servo object for arm joint 2
   
   void setup() {
       armServo1.attach(9); // Attach servo to pin 9
       armServo2.attach(10); // Attach servo to pin 10
   }
   
   void loop() {
       armServo1.write(90); // Move to 90 degrees
       armServo2.write(90);
       delay(1000); // Hold position for 1 second
   }
   

Step 5: User Interface Development

1. Create a Remote Control Interface : Develop a simple user interface using Python and MQTT for remote control.

   python
   DownloadCopy code
   import paho.mqtt.client as mqtt
   
   def on_connect(client, userdata, flags, rc):
       print("Connected with result code " + str(rc))
       client.subscribe("robot/control")
   
   def on_message(client, userdata, msg):
       command = msg.payload.decode()
       if command == "forward":
           # Send command to Arduino to move forward
           pass
   
   client = mqtt.Client()
   client.on_connect = on_connect
   client.on_message = on_message
   
   client.connect("broker.hivemq.com", 1883, 60)
   client.loop_start()
   

Step 6: Testing and Iteration

1. Test the Robot : Conduct tests to ensure that all components are functioning as expected. Adjust the code and hardware as necessary based on test results.
2. Iterate on Design : Based on testing feedback, make improvements to the design and functionality of the robot.

Conclusion

By following these steps, you will successfully develop the Bonic Bot S1, a multifunctional mobile robot capable of performing various tasks in diverse environments. The integration of advanced sensors, actuators, and a user-friendly interface will enhance productivity and efficiency in various applications.
