I came across the Edison Robots and thought that it would be a way my 3 boys could build lego bots and have them “battle”.  Unfortunately, I’ve come across an issue with getting the IR remote functionality to work fully.  I believe this is a limitation of the IR protocol, but I was hoping someone might have some insight and a solution.

I’ve successfully programmed all 3 Edisons with 3 different Sony Universal remotes.  They will each work separately without any issues.  The problem I’m having is when they’re used at the same time.  When a command is sent from one remote to it’s paired Edison (A) and other remote is controlling it’s paired Edison (B), it stops or changes the behavior of the first Edison (A).  My guess is since they are all using the same IR frequency, they’re getting in the way of each other.

Is there a way to change the IR frequency that each Edison receives?

Hi

You are correct, the remotes are all using the same IR frequency and therefore have issues with crosstalk and interference. 

We are aware of this issue and it is on our list to look into, unfortunately, at this time I am unable to give a timeline for a possible solution.

In the meantime, I would recommend your boys program a sumo program each (stay inside a ring, with the possible extension of detecting an opponent and charging) and have the Edisons battle autonomously

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.
