Troubleshooting your Edison robot

Looking for some help to solve an issue with your Edison robot? You have come to the right place!

If you are new to using Edison, you may want to download the free Getting started with Edison guide which includes step-by-step instructions walking you through getting your robot and programming device set up.

Please follow the steps below.


Step 1: Check and change the batteries

Low or flat batteries can cause some weird behaviour from Edison, resulting in a range of issues with the robot. That’s why the best first step is to try changing or recharging Edison’s batteries. 

Be sure you are using the correct batteries and that you have them properly inserted into Edison.

If using disposable batteries: only use alkaline batteries. (These are the most common AAA batteries you will find in just about any shop.) Never use heavy-duty, super heavy-duty or carbon zinc batteries.

If using rechargeable batteries: only use nickel metal hydride (NiMH) rechargeable batteries. Do not use lithium rechargeable batteries. 

Changed the batteries and still having trouble? Please continue to the next step.

Step 2: Turn your device’s volume all the way up

To be able to program Edison, most devices will need the volume turned up to maximum or 100%. Check to make sure your tablet or computer’s volume is turned up to full. 

Many devices have built-in safety settings that reduce the volume when an audio device is connected using the headphone jack. That’s why it is important to double check that your volume is turned all the way up after plugging in the EdComm programming cable to your device.

Confirmed the volume settings are correct but still having trouble? Please continue to the next step.

Step 3: Disable sound enhancements

Try this step if you are:

  • programming or updating Edison using a Windows computer or laptop, and
  • having issues with your program or update failing.

Windows machines often have sound enhancements which may be causing your program or update to fail. Disabling these sound enhancements can resolve the issue.

This quick tutorial video will show you how to disable Windows sound enhancements.


If the ‘Disable Sound Enhancements’ checkbox was missing on your machine, or if you have disabled basic sound enhancements, but your Edison is still not successfully downloading, your machine may have 3rd party sound enhancements installed.

Please select the tutorial for your machine in the ‘disable 3rd party sound enhancements’ drop-down below for step-by-step guidance on how to disable the 3rd party sound enhancements.

Disable 3rd party sound enhancements
Dolby Home Theater - Acer and Lenovo computers
DTS Audio - HP computers
Dell Audio - Dell computers

Sound enhancements disabled and still having trouble? Please continue to the next step.

Step 4: Confirm your program is downloading to Edison

While your program is downloading, Edison will make sounds similar to an old dial-up modem. This is the sound of the program being downloaded into Edison.

Once the program has finished downloading, Edison will make one of two sets of beeps:

  • the ‘success sound’ set of beeps, indicating Edison has successfully received the program, or
  • the ‘fail sound’ set of beeps, indicating the program failed to download correctly.

The following recordings are the series of beeps for both a successful program and a failed program. Please listen to the sounds, then try downloading a test program to your Edison to confirm the program is being successfully downloaded.

If you hear the ‘fail sound’ or if the program is being successfully downloaded, but the Edison robot is not executing the program correctly, please continue to the next troubleshooting step.
