As the Iraqi army retreated at the end of the first Gulf War, they took the term “scorched Earth policy” quite literally. Kuwaiti oil wells were set alight en masse, creating towering infernos that blackened the sky.
As it turns out, extinguishing a burning oil well is no easy feat. In the face of this environmental disaster, however, a firefighting team from Hungary made a name for themselves out on the desert sands, astride a jet-engined tank named Big Wind.

Firefighting is a difficult and dangerous job, which puts humans on the front line to save life and property on a regular basis. It’s a prime candidate for some robot helpers, and [Ivan] has stepped in with a fun build that, while it won’t be serving in your municipal department any time soon, gets us thinking about the possibilities.
It’s a radio controlled robot with an Arduino Uno for the brains. A couple of motor driver boards are used to run four windscreen wiper motors for propulsion. Long before the days of online shopping, the wiper motor was a hacker staple – a cheap, readily available high torque motor that could be easily driven for a range of hobby projects. They say only 90’s kids remember.
As far as water delivery goes, this robot is a little short on credentials, carrying only 1 litre of water. However, we appreciate [Ivan]’s use of a Tupperware container as a tank – with a few add-on fittings, this could be a great way to hold water in other projects. The small DC-powered pump is controlled by an industrial solid state relay – a good choice for a robot that may get wet. There’s an onboard CO2 extinguisher as well, but it’s sadly not plumbed into anything just yet.
This build is an [Ivan] classic – big, fun, and 3D printed on a much larger scale then we’re used to. It’s a strong follow up to his impressive tank build we saw earlier. Video after the break.
