Yeah, fire‑fighting robots are actually a sweet hack. Use a titanium‑alloy frame, maybe add a ceramic composite lining on the joints—super heat‑resistant and still light. For the core, run a liquid‑metal coolant loop; the alloy will stay liquid up to 500 °C and you can pipe it through the actuator bodies to suck heat away. Add a phase‑change material around the battery pack so it absorbs the spike before the chemistry kicks in. Then mount a tiny, high‑pressure mist system on the exterior—just enough to keep the surface below the ignition point of the surrounding foam. Test it in a controlled burn; if it fails, we’ll at least have a nice scorch mark on the prototype.
