The show was based on an original idea of Adam Clark, creator of the robot 259 which featured on Robot Wars.
The set was one of the biggest sets ever built for a children's show, which included urban and industrial landscapes, countryside, lakes and rivers.
Each episode featured teams of four children using three robots best suited for the challenge. The teams had to battle against the clock in a mission to save a town called Calamity City from a disaster such as nuclear meltdown, or environmental catastrophe. They tasks required a balance of problem-solving skills, driving skills and technical ability.
