This video explains the "robotic stack," a framework for understanding the different layers of the robotics industry and identifying investment opportunities. Brian Feroldi breaks down the stack into four tiers: the physical components (muscles), the sensory systems (eyes and nerves), the computational layer (brain), and the operators who integrate robotics into their businesses. The video emphasizes that the true value and growth potential lie not just in building robots, but in owning the intelligence and software that orchestrates them.
