3D Printable Virtual Wall for iRobot Roomba

Sometimes it can be helpful to exclude a Roomba robotic vacuum cleaner from certain locations. You can buy a factory virtual wall for this purpose, but you can also make it yourself using an arduino nano and some cheap parts.

I used these for the project:

Nano V3.0 Atmega328

Super-Bright 5mm IR LED and IR Receiver Diode – 940nm

Resistor Kit Assortment, 0 Ohm-1M Ohm

9V Battery Clip

Duracell 9V Alkaline Batteries

Small Black ON Off Appliance Toggle Switch

This topic has been explored many times, now I want to publish my version. I made a 3D printable outer case for it.

I have made the plan available below:

I suggest you turn the model over to print, then no support is needed.

Also print the bottom plate. When done, just snap it to the bottom

Build the following circuit with the arduino nano.

Open the Arduino app and upload the following simple code to your arduino nano

#include <IRremote.h>

// irLed ==> D3!
IRsend irsend;  

void setup()
{
  irsend.enableIROut(38);
}

void loop()
{
  irsend.mark(1000);
  irsend.space(1000);
}
