Robot arm collective builds 0.5mm-precision wood model to plan grain-aware clock milling

lukechurch demonstrated a precision-tiered spatial workflow: a collective of VBR Rubi robot arms used mounted cameras to build a high-resolution model of a wind-fallen Scottish beech log (seasoned 12 months), planning how to mill it into a clock while respecting the grain. The key insight is matching information precision to task: rough arm positions suffice for motion planning and serve as priors to accelerate photogrammetry, while toolpath planning needs knot locations under 0.5mm. Driving infill by purpose saved hours of compute and terabytes of data.
