Overview

This project implements a quadruped robot named OK1 using Arduino, with support for ROS and Gazebo simulation. The robot is designed to walk on four legs and can be controlled both physically and through software.

Features

• Quadruped robot hardware based on Arduino Mega 2560.
• A Remote Controller
• ROS (Robot Operating System) support for high-level control and communication.
• Gazebo simulation environment for testing and development.
• Modular and extensible design for customization.

Folder Structure

• /CAD-Hardware: Contains 3D printing files for the robot parts.
• /Arduino: Arduino code for controlling the robot.
• /ROS_ws: ROS packages for communication and control.
• /media: Some useful images for implementation.

Getting Started for ROS and Gazebo

Follow these steps to get started with the ROS and Gazebo simulation environment for the OK1 Quadruped Robot:

1. Clone the Repository:

   git clone https://github.com/omerKurkutlu/OK1-QuadrupedRobot.git

2. Navigate to the ROS Workspace:

   cd ROS_ws

3. Build the ROS Workspace:

   catkin_make

4. Source the Workspace:

   source ./devel/setup.bash

5. Launch the Robot:

   • For Rviz Visualization:

     roslaunch ok1_moveit_config demo.launch

   • For Gazebo Simulation:

     roslaunch ok1_moveit_config demo_gazebo.launch

These commands will set up the necessary environment for ROS and Gazebo, allowing you to visualize and simulate the OK1 Quadruped Robot. Make sure to follow the instructions carefully, and feel free to explore the ROS workspace for additional details.

Electronics Assembly

Below is a simplified Fritzing schema providing an overview of the electronics assembly for the OK1 Quadruped Robot project. Please note that this schema is incomplete and serves as a starting point. Refer to the detailed schematics and documentation for accurate connections.

You can also refer those images for electronics:

• Image 1: OK1 Printing Files)
• Image 2: OK1 Printing Files)
• Image 3: OK1 Printing Files)
• Image 4: OK1 Printing Files)

Wiring Instructions

• Connect the components according to the Fritzing schema.
• Ensure proper power distribution and regulation.
• Check and cross-verify the connections with the detailed schematics.

Arduino Code Compiling and Uploading

Before compiling and uploading the Arduino code for the OK1 Quadruped Robot, ensure that you have downloaded the required libraries. Follow these steps to set up and upload the code:

1. Download Required Libraries:

   Open the Arduino IDE and navigate to Sketch > Include Library > Manage Libraries.... In the Library Manager, search for and install the following libraries:

   • Servo.h
   • MPU6050.h
   • Wire.h
   • PID_v1.h (For self-balance which is not implemented in this version)
   • SPI.h
   • nRF24L01.h
   • RF24.h
   • myServo_class.h (Custom Library - No download required)
   • Quadruped.h (Custom Library - No download required)

   Make sure to install the specific versions of the libraries if mentioned in your project documentation.

2. Open the Arduino Sketch:

   Open the main Arduino sketch file located in the /Arduino directory of your project.

3. Configure Arduino Board:

   Go to Tools > Board and select the appropriate Arduino board. Ensure that the correct port is selected under Tools > Port.

4. Verify and Upload:

   • Click on the checkmark icon (Verify) to compile the code and check for any errors.
   • If the code compiles successfully, click on the right arrow icon (Upload) to upload the code to the Arduino board.

5. Monitor Serial Output (Optional):

   Open the Serial Monitor (Tools > Serial Monitor) to view debug information and status messages if your code includes serial communication.

6. Troubleshooting:

   If you encounter any issues during compilation or uploading, refer to the troubleshooting section in the project documentation or community forums.

Remember to customize the instructions based on the specific details of your project, including the names of libraries and any additional configurations users might need to make. If you have a specific troubleshooting section or documentation, it's a good idea to guide users there for more in-depth assistance.
