Startup cost: $500 - $3k

Setup costs range from $500 to $3,000 for starting a Robotic Process Automation with Physical AI side hustle. At the minimum end, one would need basic hardware like a Raspberry Pi or Arduino board, which can cost around $50-$100, along with software tools for RPA development that may total around $200-$400. Optional expenses could include buying additional sensors or actuators for more advanced projects. On the higher end, investing in premium RPA software licenses, advanced sensors, quality robotic kits, and educational resources could push the costs up to $2,000-$3,000. Recurring fees may include software subscription renewals or additional components for scaling up the business. Online discussions suggest that costs can increase as one delves into more complex projects or aims for professional-grade automation solutions. For a friend looking to take this seriously, I would recommend budgeting around $1,000-$1,500 initially to have a solid foundation for growth and learning.
