Beginner friendly: Challenging

Swarm Robotics and Multi-Agent AI Systems require a deep understanding of robotics, artificial intelligence, and programming. To start making money with this side hustle, beginners would need to invest significant time and effort in learning these complex fields. Online resources like specialized courses, forums, and tutorials can help, but the learning curve is steep. The setup costs can range from $500 to $2000 for equipment and software. Profit could be achievable after at least 6 months to 1 year of dedicated learning and experimentation. I'd rate it a 1 because the technical expertise and financial investment needed make it very difficult for the average person to start earning a profit.
