The mechanical Robot Ant 3D was made by my mate 14c0 of Mi.S.Fu. Sound design made with iZotope Iris and Pro Tools. I emphasised the Ant warrior breathing to characterise its rage and waiting to fight against an enemy.
I would have loved to get the mechanics a little bit more robotic/futuristic, but I liked the idea of clunking parts more.
