EdVenture 3 – Follow torch

Edison loves light! He will drive towards the brightest light source even if it means falling off the table. Such is love!

This barcode activates Edison’s light following program. The program uses Edison’s light sensors and motors to follow a torch (American English: flashlight).

Reading the barcode

  1. Place Edison facing the barcode on the right side
  2. Press the record (round) button 3 times
  3. Edison will drive forward and scan the barcode

Barcode – Follow torch

What to do

You will need a torch/flashlight and a flat surface away from any really bright light, such as sun light.
Press the play (triangle) button and aim the torch at Edison. Once he ‘sees’ the bright source of light he will drive towards it.
By moving the torch you can control where Edison drives to. Does this behaviour remind you of anything?

Edison the light following robot


This is one of Edison’s most interesting programs, because it mimics the behaviour we see in some flying insect. I’m sure you’ve seen moths on a hot summer night swarming around a bright light. This type of robotic behaviour is called ‘phototropism’ and is normally found in plants that grow towards the sun.
This program is also very interesting, because Edison is behaving autonomously. This means that he is thinking for himself and responding to changes in his environment.
Is he alive?

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.
