GRAIL addresses Europe’s need for trustworthy, sovereign GenAI in robotics, lowering adoption barriers in manufacturing while respecting AI Act, GDPR, and NIS2. It strengthens technological sovereignty and competitiveness while tackling the robotics data gap: existing sources (teleoperation, egocentric video, simulation) cover only a fraction of the data needed for robust foundation models. Unlike in text and vision, robot data cannot simply be scaled: collection is slow, costly, and infeasible at trillion-scale. Bridging this gap requires modularity, knowledge reuse, and targeted data generation rather than brute-force collection. Monolithic approaches are data-inefficient, struggle with explainability and fail to cope with industrial complexity. GRAIL is an agentic integrated architecture where modularity and integration reinforce each other. Specialised agents address planning, grounding, and control, while integration ensures collaboration over a common latent substrate. Human centricity is ensured by decoding agent behaviour into rationales understandable by workers, allowing them to follow, trust, and intervene through HITL&HOTL mechanisms. This enables continuous learning, cross-embodiment skill reuse (collaborative and industrial arms, humanoids), and distillation for deployment on edge devices. Predictive world models, deterministic fallbacks, and runtime safeguards ensure robots reason, adapt, and act safely under physical constraints. Impact is driven by 10 industrial partners and 5 use cases (automotive, aerospace, intralogistics, steel, electronics), validated on 10+ robots. GRAIL scales through 40+ FSTP projects and 4 Test Hubs, supported by EuroHPC and national HPC, with model compression and federated learning reinforcing efficiency and sustainability. It delivers verifiable competence, safeguards trust through risk monitors, cyber testing, and ethical governance, and ensures interoperability through AIoD, balancing open access and EU sovereignty. GRAIL will launch 3 Open Calls to select at least 40 third party projects aimed to accelerate data generation, model fine-tuning and large-scale industrial adoption of GRAIL’s foundation model: ● Genesis Open call to select at least 10 third-party projects aimed at data expansion and democratization: crowd-sourced multimodal data (including phone capture), incentive mechanisms/gamification, and low-cost capture devices (e.g. hand-held grippers). ● Ascent Open call to select at least 20 third-party projects emphasising industry-driven validation and early deployment, with high-value industrial data under protected licenses, validation protocols, and KPI reporting and early integration activities. Results feed back into the GFM training loops and the benchmarking suite. ● Summit Open call to select at least 10 third-party projects focused on scaling adoption: sector-specific fine-tuning, integration into production systems and pipelines, and user-oriented interfaces. Crucially, OC3 extends the GFM’s impact beyond GRAIL’s five umbrella UCs, validating it in additional domains and platforms and generating concrete exploitation pathways and business cases for early adopters, thus maximising generalisation potential. OC2 will leverage the results of OC1 (datasets and data-capture tools) as well as the challenges proposed by the Use Cases and complement the outcomes already achieved within the project. OC3 will go beyond OC2, extending the challenges to other manufacturing sectors and demonstrating the generalization of the approach.
