To our way of thinking, the whole purpose behind robotic vacuum cleaners is their autonomy. They’re not particularly good at vacuuming, but they are persistent about it, and eventually get the job done with as little human intervention as possible. So why in the world would you want to convert a robotic vacuum to radio control?
For [Lucas], the answer was simple: it was a $20 yard sale find, so why not? Plus, he’s got some secret evil plan to repurpose the suckbot for autonomous room mapping, which sounds like a cool project that would benefit from a thorough knowledge of this little fellow’s anatomy and physiology. The bot in question is a Hoover Quest. Like [Lucas] we didn’t know that Hoover made robotic vacuums (Narrator: they probably don’t) but despite generally negative online reviews by users, he found it to be a sturdily built and very modular and repairable unit.
After an initial valiant attempt at reverse engineering the bot’s main board — a project we encourage [Lucas] to return to eventually — he settled for just characterizing the bot’s motors and sensors and building his own controller. The Raspberry Pi Zero he chose may seem like overkill, but he already had it set up to talk to a PS4 game controller, so it made sense — right up until he released the Magic Smoke within it. A backup Pi took the sting out of that, and as the brief video below shows, he was finally able to get the bot under his command.
[Lucas] has more plans for his new little buddy, including integrating the original sensors and adding new ones. Given its intended mission, we’d say a lidar sensor would be a good addition, but that’s just a guess. Whatever he’s got in store for this, we’re keen to hear what happens.
