Members of the OU Robotics Outreach Group have been running hands on school and community workshops using the Lego Mindstorms robot invention system. Typically, these activities have been based around remote control activities using prebuilt robots, programming workshops using prebuilt robots or hybrid workshops involving simple robot construction and programming tasks. In this presentation, we describe a new activity format - a robot construction activity using a preprogrammed robot controller capable of solving a situated task based on the popular RoboCupJunior robot rescue challenge.
