Spain's national robot contest was held on Sunday in Barcelona.

It was the 12th such contest, and the most competitive prototypes won prizes in different categories such as light and heavy weight sumo wrestling and racing.

The winners, from different Spanish regions as well as neighbouring Andorra, were awarded with small sums of money as well as public recognition in the robotic industry.

According to one participant, Jordi Armengol, the competition got increasingly difficult each year.

One of the aims of the National robot contest is to stimulate originality and creativity in the entrants.

The activities also included open classes to teach children how to programme robots.
