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.

The original description and the downloadable .stl file can be found here.

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

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

Just snap the bottom in.

Build the following circuit

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

#include <IRremote.h>

// irLed ==> D3!
IRsend irsend;  

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

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

.

I hope you enjoyed this post. I look forward to your feedback.
