Robots are evolving from isolated, closed-system hardware into autonomous economic participants on the blockchain. The convergence of mature AI, automation, and Web3 infrastructure is equipping robots with digital identities, incentive mechanisms, and settlement capabilities, enabling them to engage in real-world production and collaboration. This article provides a systematic overview of the Web3 Robots sector, analyzing key projects that are building its foundational layers. The transition marks a significant shift. Previously confined to labs and controlled industrial settings, robots are becoming on-chain economic entities. Their generated data, executed actions, and produced value can now be recorded, incentivized, and traded, blurring the lines between the physical and digital worlds. Several representative projects are pioneering different aspects of this emerging machine economy: **OpenMind** is developing OM1, an open-source, AI-native robot operating system often called the “Android for robots.” Its FABRIC layer is a decentralized AI control protocol facilitating large-scale robot collaboration, trust networks, and micro-payment incentives. **Konnex** is building a permissionless, decentralized marketplace for robotic intelligence and physical labor. It enables autonomous robots to contract with each other, trade AI capabilities, and settle payments in stablecoins through core technologies like Proof-of-Physical-Work and a Universal Task Language. **peaq** is a Layer-1 blockchain specifically designed for the Machine Economy. It provides decentralized machine identities, on-chain wallets, and tools for machines to autonomously transact and generate revenue, with over 60 real-world applications already deployed. **Virtuals Protocol** functions as a launchpad for tokenizing AI agents and robots, facilitating on-chain coordination and monetization, particularly for applications in gaming and entertainment. **Geodnet** operates the world’s largest decentralized RTK network, providing centimeter-level precision positioning essential for robotics and autonomous vehicles, and features a real-yield buyback model for its token. **XMAQUINA** is a DePIN (Decentralized Physical Infrastructure Network) project that uses DAO governance to manage tokenized robotics companies, offering a “Robotics Bank” and launchpad for machine economy ventures. **Robonomics**, one of the earliest platforms in this space, provides Web3-based cloud services and smart contract coordination for robots and IoT devices. The emergence of this sector is a direct result of advancing automation, AI, and Web3 infrastructure. On-chain identity, incentives, and settlement mechanisms create new possibilities for machine participation in economic activities. Currently, the focus remains largely on foundational infrastructure development, with widespread, real-world application still in its early stages. The long-term value of associated tokens is intrinsically linked to actual deployment and usage metrics. While it will take time to verify if robots become a core component of the Web3 ecosystem, the sector has demonstrably progressed from conceptual discussion to a tangible and observable phase of development as of 2024.
