ND-1 is an on-device Physical AI mobile robot solution transforming construction sites into automated logistics ecosystems. Traditional construction logistics rely heavily on manual labor to transport heavy materials like long pipes, cement, and drywall—causing severe operational bottlenecks, safety hazards, and project delays amid critical labor shortages. ND-1 resolves these challenges with an onboard Vision-Language-Action (VLA) model, enabling autonomous perception, identification, and material gripping. For oversized 4-to-6-meter pipes, two ND-1 units synchronously collaborate to lift and transport payloads as a unified system. Integrated with EVW-2, an attachable elevator automation robot, ND-1 autonomously boards standard elevators to navigate multi-story sites without human intervention. Bringing the continuous 24/7 efficiency of Amazon fulfillment centers to harsh construction environments, ND-1 eliminates safety hazards, accelerates data center completion, and achieves scalable heavy-material automation—marking a true revolution in construction sites.
