Modded Robot Vacuum Can Whistle While It Works

January 28, 2021 by 7 Comments

While repairing his Neato Botvac D85, [elad] noticed the little fellow was packing a real speaker and not just a piezo buzzer. Thinking this was a bit overkill just for the occasional beep and bloop, he decided to round things out with a Bluetooth receiver and a second speaker so the bot can spin some stereo tunes while it gets down and dirty.

It wasn’t a very expensive modification. Between the VHM-314 Bluetooth receiver, the 3 watt PAM8403 amplifier, and a matching speaker, [elad] says he was only a few bucks out of pocket. Truly a small price to pay for a robotic vacuum that plays its own theme music as it travels around the house. A small demonstration of the Neato’s new musical talents can be heard in the video after the break.

Perhaps unsurprisingly, the audio hardware puts enough of a drain on the robot’s batteries at max volume that there’s a noticeable reduction in runtime. He’s not too worried about it right now, but [elad] mentions that if it ends up keeping the vacuum from being able to complete it’s whole cleaning cycle, that he might look into adding a dedicated power source to keep the music going.

Despite some early encouragement from iRobot, we haven’t seen quite as much robot vacuum hacking as you might think. It’s always interesting to get a glimpse inside of these automated housekeepers, especially when it’s a custom built machine.

New Brain For Smart Vacuum

June 12, 2017 by 10 Comments

The ESP8266 has found its way into almost everything now. With its tiny size, low price tag, and accessible programmer, it’s perfect for almost any application that requires WiFi. [HawtDogFlvrWtr] decided that will all of the perks of the platform, an ESP8266 was practically begging to be shoehorned into his automatic vacuum cleaner. This isn’t a Roomba, though, it’s a Neato that now has a custom WiFi interface.

The new WiFi modification comes with some additional features as well. First of all, it ditches the poorly designed default user interface (often the most annoying proprietary component of any consumer product). In addition, the vacuum can now be placed on a completely custom schedule and can also be deployed at the push of a button. Now that it has a custom interface, it can report its status over the network to a phone or other computer as well.

[HawtDogFlvrWtr] is still developing his project and it looking for some help beta testing his new platform. He also has how to videos on his project page if you’re in the process of tearing apart your own. There are many other ways of modifying vacuum cleaners to add other useful features as well.

Hackaday Prize Entry: BunnyBot Helps Out All On Its Own

September 2, 2016 by 14 Comments

[Jack Qiao] wanted an autonomous robot that could be handy around an ever-changing shop. He didn’t want a robot he’d have to baby sit. If he said, ‘bring me the 100 ohm resistors’, it would go find and bring them to him.

He iterated a bit, and ended up building quite a nice robot platform for under a thousand dollars. It’s got a realsense camera and a rangefinder from a Neato robotic vacuum. In addition to a mircrophone, it has a whole suite of additional sensors in its base, which is a stripped down robotic vacuum from a Korean manufacturer. A few more components come together to give it an arm and a gripper.

The thinking is done on a  Nvidia Jetson TK1 board. The cores on the integrated graphics card are used to perform faster computer vision calculations. The software is all ROS based.

As can be seen in the video after the break. The robot uses SLAM techniques to successfully navigate and complete tasks such as fetch resistors, get water, and more. [Jack Qiao] is happy with his robot, and we would be too.

In Soviet Russia, DIY Laser Rangefinder Scan YOU!!

June 5, 2016 by 40 Comments

Yakov Smirnoff used to say, “In America, you can always find a party. In Soviet Russia, Party finds YOU!!” Only here, it’s a laser rangefinder.

In this project (automatic translation), [iliasam] makes his own scanning laser rangefinder, like the ones that we’ve seen in fancy vacuum cleaners. But he does it from scratch.

b91e3927436e885627e52179a5ed6c70While this sort of thing is easy if you have a webcam and a ton of processing power to throw at it, [iliasam] takes the hard way out — measuring the parallax of the reflected spot through a lens on a linear image sensor (which renders as “photodetector line” in translated Russian).

Linear image sensors are a lot like the elements in your CMOS digital camera, with the exception that the elements are arranged in a line instead of a plane, and they’re a lot easier to interface with a microcontroller. Hold a data line high to take an exposure, and then clock out the (analog) voltage values that correspond to the amount of light that hit each cell in the line array. While [iliasam] paid an estimated $18 for his, we’ve found them much cheaper on eBay. And there’s usually a linear sensor, often RGB and complete with driver circuitry, in a scanner if you take one apart. This could be done for just a few bucks if you were thrifty.

Robotic Vacuums Get Torn-down For Design Showdown.

April 8, 2016 by 7 Comments

Fictiv runs a 3D printing shop. They have a nice interface and an easy to understand pricing scheme. As community service, or just for fun, they decided to tear-down two robot vacuums and critique their construction while taking really nice pictures.

The first to go is the iRobot 650 model. For anyone who’s ever taken apart an iRobot product, you’ll be happy to know that it’s the same thousand-screws-and-bits-of-plastic ordeal that it always was. However, rather than continue their plague of the worst wire routing imaginable, they’ve switched to a hybrid of awfulness and a clever card edge system to connect the bits and pieces.

The other bot is the Neato XV-11. It has way fewer screws and plastic parts, and they even tear down the laser rangefinder module that’s captured many a hacker’s attention. The wire routing inside the Neato is very well done and nicely terminated in hard-to-confuse JST connectors. Every key failure point on the Neato, aside from the rangefinder, can be replaced without disassembling the whole robot. Interestingly, the wheels on both appear to be nearly identical.

In the end they rate the Neato a better robot, but the iRobot better engineered. Though this prize was given mostly for the cleverness of the card edge connectors.

How To Use Lidar With The Raspberry Pi

January 22, 2016 by 29 Comments

The ability to inexpensively but accurately measure distance between an autonomous vehicle or robot and nearby objects is a challenging problem for hackers. Knowing the distance is key to obstacle avoidance. Running into something with a small robot may be a trivial problem but could be deadly with a big one like an autonomous vehicle.

My interest in distance measurement for obstacle avoidance stems from my entry in the 2013 NASA Sample Return Robot (SRR) Competition. I used a web camera for vision processing and attempted various visual techniques for making measurements, without a lot of success. At the competition, two entrants used scanning lidars which piqued my interest in them.

Neato Botvac LiDAR Repair Includes Juicy Pics And A Tool Hack

September 28, 2015 by 4 Comments

It seems second nature to us and it’s one of the ways we hackers are different from the larger population… sometimes we absolutely insist on buying something that is already broken. Which is where we join [Anton] as he reverse engineers, debugs, and repairs a broken Neato Botvac’s LiDAR system all in the name of having clean floors at a fraction of the cost.

Now keep your head on a swivel ’cause along the way [Anton] has the all-too familiar point in his repair where he puts the original project on hold while he makes a specialized tool he needs to finish the job. It’s hard to tell which is more impressive: turning a laptop webcam into a camera capable of clearly viewing bond wires and (wait for it!) where they are attached on the Silicon, or that he (yeah, we were making a comparison…member?) went straight back to solving the original problem. [Anton] did split this project into two separate blog posts, the first one is linked above and it’s not until the second post that he fixes the original problem. Perhaps there was a bit of scope creep, which was the reason for the separate blog entries? At any rate, [Anton] does a great job documenting the process along with what he calls some ‘juicy pictures’ and you can see a few of them after the break.

It’s been a while since we’ve seen a Neato hack (there’s pun in there somewhere, commenters below us will surely wipe the floor with it). LiDar on the other hand has been covered more recently in a Police LiDAR Tear Down and another post relating more directly to [Anton’s] repair.
