Chernobyl’s Robots, Or The Hackathon From Hell

A detailed look at the frantic, improvised robotics effort following the 1986 Chernobyl disaster, described as a 'hackathon from hell.' Teams from across the USSR and allied nations rapidly designed and deployed robots for radiation measurement and debris removal, often skipping testing entirely. Many failed — the RR-1 overstated radiation by a factor of ten, the RR-2 and RR-3 tipped over after helicopter deployment. More reliable designs like the BAER Beloyarets used vacuum tubes, relays, and combustion engines (far less radiation-sensitive than batteries). Eventually bulldozer-type robots like the STR-1 cleared radioactive debris from rooftops. The lessons from this chaotic engineering sprint remain relevant to ongoing nuclear cleanup efforts like Fukushima Daiichi.
