Maker Marcel Varallo doesn’t just vacuum, he goes to war against the dust mite.
Lucky for those who hate sweeping and vacuuming floors, there are robotic devices that can take care of these tedious tasks for us. And although Roombas do a fairly decent job in cleaning our homes, like with most things, it could do better. This is why Marcel Varallo decided to upgrade his iRobot 530 Series into a dust mite-battling vehicle that he calls Doomba.
Ever since the Roomba made its debut, hackers have loved getting their hands on the bots and modifying them to suit other purposes. Initially, Varallo simply wanted to “jazz up the default speed” of his roving gadget, but why stop there? He proceeded to make a few more modifications, such as mounting a webcam to the front and adding a UE Boombox that emits the iconic Jaws theme and the Flight of the Valkyries as it sucks up its prey.
A Raspberry Pi with Wi-Fi enables webcam hosting, remote triggering of tasks and schedule management, while wireless control is handled through a PS2 receiver dongle and an Arduino Nano (ATmega328). Varallo even included a capacitor bank to prevent brownouts from the Doomba’s SPI port.
“By the end of all this it had blown out to something much bigger than I intended and was more work than I would have liked,” the Maker admits. Those wishing to mod their own robotic vacuum should check out Varallo’s detailed project page.
