The FIRST LEGO League robotics competition has been running annually since 1999, when it started in the US with 9500 children. In the 2005 season, 60,000 children (aged 9 to 16) participated in 7460 teams worldwide. There were 200 qualifying and 56 championship tournaments in North America and 98 qualifying and 12 championship tournaments in the rest of the world.

The teams are judged in four areas at the tournaments:

  • Robot design and technical presentation
  • Robot performance on a challenge mat
  • Teamwork
  • Research project and presentation

The challenge for the 2005 season was called Ocean Odyssey. It was on the topic of bio-diversity in the oceans.

We learned how to build and program an autonomous robotic vehicle using the LEGO Mindstorms equipment, tackling serious engineering problems along the way.

The robot had to navigate a table with obstacles and carry out tasks (such as retrieving objects) to achieve as many points as possible in 2.5 minutes. At the Swindon heat, we were aiming for up to 295 points out of a maximum of 400. We averaged about 150 points and our winning score in the final was 182 points. At the UK final, we had changed the robot a little and ran out of time to get the programs working properly with it. By the OEC, we had improved the accuracy of our robot and tested the programs properly. We averaged 226 points out of the 300 we were attempting.

SHELL chose to do a research project about sound pollution in the oceans. Having researched sound pollution on the Internet and by visiting the WDCS, we put together a five-minute soundtrack of sea sounds. We used this soundtrack as a background to our five-minute presentation of the problems that noise pollution (for example, sonar and drilling) causes for cetaceans (whales and dolphins).
