Robot Wars comes home in this new, louise Brady-hosted smashnbash show which will see families go head-to-head in a series of gloriously dappy technological challenges, utilising only the contents of their houses. First up, the Hockeys and the Smiths are charged with assembling machines in order to destroy an unsuspecting shed. Stupid? Yup. Ecologically sound? Barely. A good laugh? Definitely.
