RoboCore (ROBOC) on Ethereum is a groundbreaking decentralized infrastructure powering Physical Artificial Intelligence (PAI). It integrates modular AI brains with robotic bodies, creating an open network for AI training, robotic deployment, and autonomous service delivery. The DePAI Brains module, represented as NFTs, are trainable, composable, and upgradeable by the community. Additionally, blockchain-registered physical robots can adopt these AI brains and execute real-world tasks, ranging from drones and robotic arms to humanoids and warehouse bots. The project also features AI-Training Mining, allowing users to earn tokens by contributing to the development and improvement of AI models through data labeling, simulations, and algorithm refinement. This unique ecosystem tokenizes Physical AI, empowers global collaboration, and automates real-world tasks transparently using smart contracts, creating a trusted environment for deploying AI in physical spaces.
