How it works

Each point on the panel carries a damage value D(x,y) ∈ [0,1] — 0 is pristine coating, 1 is a full scratch through to bare metal. A repair nanorobot near position x is "idle" until the locally sensed damage crosses a threshold θ, then it activates and steers toward the worst damage in its sensing radius:

activate(robot) ⇔ D(x_robot) > θ

dD/dt = -k · n_active(x,t)   for D(x,t) > 0
        0                    otherwise

where n_active(x,t) is the number of activated robots currently working within a small repair radius of point x, and k is the per-robot repair rate. This mirrors two real automotive nanotechnologies from the source article: distributed nanosensor networks that continuously monitor body panels for micro-damage, and self-healing coatings whose embedded microcapsules rupture on a scratch and release a polymerizing repair agent — here the "microcapsules" are mobile robots instead of fixed capsules, so they can converge on damage wherever it occurs rather than only where they were embedded.

Nanorobot density — how many robots patrol the panel. More robots means damage gets noticed and swept faster, since n_active grows.
Sensitivity threshold θ — how much local damage it takes to wake a robot. Lower it and robots chase even faint scuffs; raise it and only deep damage gets attention.
Repair rate k — how fast each active robot heals the coating it's working on.
Repair energy used — running total of healed damage × robots involved, a proxy for the power budget a real swarm would need (thermoelectric, vibration or wireless-field harvesting, per the article).
