Learning Objectives

Hour of Code resources will be used to introduce students to programming and a basic understanding of robot construction. Students will then use critical problem-solving skills to build and code an Ozobot using Vex Robotics, preparing them for future robotics competitions.

Project Materials

  • Tablets to access
  • Ozobot Bits –
  • Vex Robots –
  • Scale model of School
  • Map of Event to be represented


Students will build a messenger robot that delivers messages to other classrooms and teachers in their school. They will learn basic computer programming, develop a scale drawing of the school, and build and program a robot.
