The FC100-B is an AI-driven safety actuator compliant with IEC 61800-5-2. It features Embedded Edge AI that monitors four internal parameters—coil current, dual encoder angle, motor temperature, and motor current—at high speeds. Utilizing a 5Mbps CAN-FD pipeline, it synchronizes with a MuJoCo Digital Twin for real-to-sim validation. In a fault event, instead of a crash, it executes a sequential safety chain: SS1(Safe Deceleration), SBC(Brake Engagement), and STO(Power Cutoff). This ensures a "Zero Actuator Drop" state, maintaining structural stability under 50kg payloads. Its unique hardware "Override Rule" allows logic to bypass AI judgment during critical spikes, providing a dual-layer safety net. This protects multi-thousand dollar assets from gravity-induced collapse, addressing the financial bottleneck of humanoid robotics development.
