Struct URDFChain 

pub struct URDFChain<const N: usize> { /* private fields */ }

FK chain using exact URDF joint transforms.

Accumulation works directly on columns:

1. Translation: t += fx·c0 + fy·c1 + fz·c2
2. Fixed rotation: (c0,c1,c2) = (c0,c1,c2) * fixed_rot
3. Joint rotation: 2D rotation on the appropriate column pair

When fixed_rot is identity (RPY = 0, the common case), step 2 is skipped entirely, making per-joint cost a single 2D column rotation plus translation — cheaper than DH.
