More than 100 primary school students went to battle with their self-designed sumo wrestling robots in a competition designed to promote science, technology, engineering and maths (STEM).

The hugely popular challenge attracted students from 32 primary schools across Limerick city and county and saw teams of 10 to 12-year-olds gather in Analog Devices on Saturday morning to build their own robots before entering the ring and pitting their robotic creations against each other sumo-style that afternoon.

Teachers, parents, family and friends cheered on the children during the tense and dramatic knock-out rounds. Not just judged on their robot’s performance, the teams were also awarded points for teamwork as well as design and innovation.

Our Lady of Lourdes were represented at the competition by Ria O'Donoghue and Rhiann Nolan.
