Dublin City University (DCU) was buzzing with excitement as 70 Irish Girl Guides showcased their skills in science, technology, engineering, and mathematics (STEM) at the FIRST LEGO League Challenge Regional. The day saw fourteen teams from across Ireland compete, demonstrating their innovation, teamwork, and problem-solving abilities through cutting-edge projects and robot design.
Octonaughts Take the Top Prize
Among the competitors were The Octonaughts, a four-Girl Guide team from Lucan Unit. They emerged victorious as this year’s Regional Champions. Their winning project focused on Sonar Technology and its impact on sperm whales.
The team explored the frequencies used in sonar technology and their effects on marine life. Their innovative solution proposed a sonar system that integrates whale echolocation clicks into sonar technology, minimizing harm to these magnificent creatures.

Their exceptional research, connection to FIRST LEGO League Core Values, and impressive robotic control skills secured them a well-deserved place in the Ireland Final, which will take place on Saturday, April 12th. There, they will compete against other top teams from across the country.
“This event is a testament to the incredible talent, passion, and commitment of our Girl Guides,” said Katie Keogh, Irish Girl Guides LEGO Representative and Mosney Unit Brownies and Guides Leader. “Each team has worked incredibly hard, and we are beyond proud of their achievements”.
