Hour of Code - Avoid and Detect with Edison activity image

​Introduce the key computational concepts of loops and an understanding of infrared light using Edison robots and the block based programming language, EdBlocks. This lesson utilises the Edison robot’s drive and obstacle detection functions through a set of progressive programming tasks.

Students learn about how Edison’s infrared light sensors work and program Edison to detect obstacles, avoid obstacles and utilise loops.

This 1-hour lesson is designed to allow students to work independently as they discover:

  • Sequential programming
  • Loops
  • Pattern recognition
  • Decomposition and problem solving

Celebrate student success!

Recognise your students’ achievements in taking on an Hour of Code challenge with Edison robots by presenting them with a certificate of completion.

Heads up

The Australian Federal Parliament has passed a law that extends goods and services tax (GST) to low value imports of physical goods imported by consumers from 1 July 2018.

This means that all customers purchasing Edison robots and accessories with an Australian shipping address must now pay GST. The GST will be automatically added to your purchase and show as a line item on your invoice.

We've detected that you are in Australia, so we wanted to let you know that we have changed your settings to view our Australian site, which displays GST inclusive pricing.
