Building a Simple Web Crawler on Nvidia Jetson Nano using Ubuntu

Requirements

• Nvidia Jetson Nano with Ubuntu installed
• Basic knowledge of Python programming

Steps

1. Install Required Packages:

   Start by updating the package lists and installing the necessary packages for web crawling:

   sudo apt update
   sudo apt install -y python3 python3-pip
   

2. Set Up a Python Virtual Environment:

   Create a virtual environment to manage dependencies for your web crawler:

   python3 -m venv crawler_env
   source crawler_env/bin/activate
   

3. Install BeautifulSoup and Requests:

   Install the Python packages BeautifulSoup and Requests for web scraping:

   pip install beautifulsoup4 requests
   

4. Create the Web Crawler Script:

   Write a simple Python script to perform web crawling. You can use a text editor or an integrated development environment (IDE) to create a file named web_crawler.py:

   import requests
   from bs4 import BeautifulSoup
   
   def simple_web_crawler(url):
       # Make a GET request to the specified URL
       response = requests.get(url)
   
       # Parse the HTML content of the page
       soup = BeautifulSoup(response.text, 'html.parser')
   
       # Extract and print links from the page
       links = soup.find_all('a')
       for link in links:
           print(link.get('href'))
   
   # Example usage
   if __name__ == "__main__":
       target_url = "https://example.com"
       simple_web_crawler(target_url)
   

5. Run the Web Crawler:

   Execute the web crawler script to see it in action:

   python web_crawler.py
   

   The script will fetch the HTML content of the specified URL and print the links found on the page.

6. Customize and Extend:

   Feel free to customize the script based on your needs. You can explore more advanced features such as handling different types of content, implementing crawling depth, or storing extracted data.

Conclusion

Congratulations! You’ve successfully built a simple web crawler on your Nvidia Jetson Nano using Ubuntu. This tutorial provides a foundation for understanding web scraping concepts, and you can further enhance and customize your web crawler for specific applications or projects.
