iRobot Roomba virtual wall DIY
thingiverse
This is a virtual wall design for a Roomba vacuum robot. I did not want to spend 70€ for two IR beacons - so I searched Thingiverse and found two designs: https://www.thingiverse.com/thing:2687981 and https://www.thingiverse.com/thing:51372 Those two designs where my base and I designed a virtual wall housing and used a simple Arduino code for the beacon signal. The tower and cover have no holes - you have to drill them for your components. I added the fritzing project and the arduino code. Enjoy making! The wall has a very wide angle so place it about half a meter away from the actual "no go line". EDIT - Parts I used: - Arduino pro mini - 5V, 16MHz - DC jack (screwmount) - 5mm IR LED lieing around - 5mm LED holder - BC547 NPN transistor - 2k2 Ohm resistor for the transistor (Arduino pin 3 -> base) - ??? Ohm resistor for the IR LED - 3mm/5V LED green (powerindicator) - toggle switch (switch between 9V battery and DC jack -> 7-16VDC RAW pin of Arduino) - 9V battery holder - wires and screws
