Extrusion-based robotic concrete additive manufacturing (RCAM) has emerged as a transformative technology in digital construction. However, one of its core challenges lies in managing material uncertainty under pressure , which often causes geometric inaccuracies during the extrusion process. This study presents an innovative pressure-based closed-loop feedback control system designed to ensure geometric fidelity by dynamically compensating for variations in material flow. By incorporating real-time sensor feedback, the system enables more consistent and reliable deposition of concrete filaments, advancing precision in automated construction. Material Uncertainty and Its Impact on Geometric Fidelity Material uncertainty in RCAM primarily arises from the variable rheological behavior of concrete mixtures influenced by temperature, moisture, and mix composition. Such inconsistencies lead to irregular extrusion pressure, which directly affects filament geometry, including width and he...
