GE Aerospace has demonstrated a worm-like robot that could one day inspect and repair jet engines. The Sensiworm (Soft ElectroNics Skin-Innervated Robotic Worm) is designed to serve as “extra sets of eyes and ears” for service operators as they examine the insides of aircraft. GE says the soft robot can minimize downtime and perform less invasive inspections and, in the future, make repairs itself.

The company compares the Sensiworm’s role in aerospace engineering and repairs to how soft robotics have allowed for minimally intrusive patient surgeries. “These technologies are enabling less invasive inspection and repair of jet engines on the wing to reduce downtime,” the company wrote. GE says the worm-like machine could give operators “virtually unfettered access” to inspect engines without disassembling them.

Resembling an inchworm, the Sensiworm (remote-controlled by operators) can crawl across various engine parts, including rotating wind turbine blades. It can sense and avoid obstacles automatically, reach places where gravity may stop other tools (thanks to its suction-cup feet) and measure the thickness of thermal barrier coatings. GE says it can even sniff out gas leaks. “With their soft, compliant design, they could inspect every inch of a jet engine, transmitting live video and real-time data about the condition of parts that operators typically check,” the company wrote.

GE Aerospace developed the robo-worm through SEMI Flex Tech, a US Army-funded public / private coalition focused on advancing flexible electronics. GE hasn’t mentioned how far along the worm is in its development or when we can expect deployment in the field. Engadget asked a company spokesperson to clarify, and we will update the article if they respond.

iRobot is running another sale on Roomba robot vacuums and Braava robot mops, which includes the Roomba 694 back down to $179. We've seen this deal pop up periodically over the past several months, but it's still $71 below the vacuum's typical street price. Outside of a very brief drop to $175 last November, it matches the lowest price we've tracked.

The Roomba 694 itself is the top pick in our guide to the best budget robot vacuums. It's an entry-level model that navigates around a room semi-randomly instead of mapping and following set paths, so it's not the most efficient cleaner, and it'll bonk into furniture around your house. That said, it's sturdily built, and we found it to work effectively across hard floors and carpet. We're particularly fond of iRobot's companion app, which makes it easy to quickly stop or start the vacuum, set a cleaning schedule, check the battery and the like. You don't need to connect to WiFi to use the device, however. iRobot says the Roomba 694 can run for up to 90 minutes before it has to roll back to its charging dock, though you'll get worse battery life depending on what floor surfaces you need to clean. 

A simpler device like this won't be as effective if you live in a particularly large home, but if you just want a no-frills option at a reasonable rate, we've found the Roomba 694 to be durable and dependable. And if something ever does break, replacement parts are readily available. 

If you're willing to pay up for a more feature-rich model, the sale also brings the Roomba j7+ down to $529. Normally, this model retails between $600 and $800. The j7+ comes with a self-emptying dock and more advanced mapping system than the 694, and it can identify and swerve away from obstacles like pet waste in real time. Currently, it's the runner up midrange pick in our guide to the best robot vacuums. Just note that, like many robot vacuums with its sort of obstacle avoidance, the j7 comes with a built-in camera, which may raise privacy concerns for some, particularly with Amazon in the process of acquiring iRobot.

Apptronik unveiled a new workforce robot today. Named Apollo, the machine is designed to “work in environments designed for, and directly alongside, humans.” The android is initially intended to move and carry cases and totes in logistics and manufacturing settings. But the Austin-based Apptronik sees Apollo expanding into “construction, oil and gas, electronics production, retail, home delivery, elder care” and more. Apollo follows Xiaomi’s reveal of the CyberOne robot last year, which looked remarkably similar to the still-unreleased Tesla Bot.

The 5-foot-8, 160-lb Apollo can lift up to 55 lbs. (Apptronik says it optimized efficiency by making its arms lighter than the weight they can lift.) It uses swappable batteries — running up to four hours per pack — which should provide more flexibility than robots that require wall charging before springing back into action. “In short, this battery-based approach means greater work output for Apollo and greater operational efficiency for customers,” Apptronik wrote in a press release today.

Apptronik

Apptronik views Apollo as a robot that can adapt to the job. The company says it built “modularity into Apollo’s design, empowering users to decide whether Apollo is best used for their applications as a true bi-pedal walking humanoid, a torso that operates on wheels or one mounted in a stationary location.” The robot has digital panels on its face and chest to provide a “friendly, human-like countenance” to make workers feel comfortable working alongside it (as it potentially moves towards automating their jobs).

Apptronik hasn’t announced public pricing for the robot. You can read more about Apollo on the company’s product page.

Robot vacuums may seem like mindless suction machines with wheels. But today, “​​basically these devices are like smartphones,” Dennis Giese, PhD student at Northeastern University who researches robot vacuum security, said. From internet capabilities to video recording to voice control, robot vacuums have become an advanced Internet of Things technology, but the security upkeep hasn’t caught up.

“You don't have any insight, what kind of data they’re recording, what kind of data is stored on the device, what kind of data is sent to the cloud,” Giese told Engadget. That might seem harmless for a device that sweeps your floors, but the real-life consequences have already taken effect.

Like in 2022 when the iRobot Roomba J7 captured private moments including photos of a woman on the toilet that the company sent to startup Scale AI to label and train AI algorithms. Amazon, which has experienced countless surveillance and data privacy scandals, is currently attempting to acquire iRobot for over $1.4 billion.

With all these features, robot vacuums can act as a surveillance system in your own home, meaning there’s a world where someone can access live view functions and spy on you. Companies can say this information is secure and only used when needed to improve your experience, but there’s not enough transparency for reviewers or consumers to figure out what’s actually going on. “People like me are catching the companies basically lying,” Giese said.

So, Giese is on a mission to give people more control over the robot vacuums in their homes because every device he’s tested has some sort of vulnerability. He spoke at DEF CON on Sunday about how people can hack their devices to disconnect from the cloud. Not only does this help protect your data from being used by the company, but it also gives access to the device so that you can repair it on your own terms. The “right to repair” ethos means that even if the warranty ends or the company goes bankrupt and stops supporting it, you can still use it.

Unfortunately, hacking into your robot vacuum’s firmware isn’t for newbies. It requires a level of technical expertise to figure out, according to Giese, but owners of robot vacuums can take steps to improve on-device data security. What you can do is make sure that you wipe all of the data before selling or getting rid of a robot vacuum. Even if the device is broken, “as a malicious person, I can just repair the device and can just power it on and extract the data from it,” Giese said. “If you can, do factory resets.”

Or, for full data privacy control but none of the convenience, stick to the standard push vacuum.

Some of the most advanced Roomba robot vacuums are on sale right now. Wellbots has the poop-detecting iRobot Roomba j7+ for an all-time low price of $549. Or, you can opt for our favorite vacuum / mop hybrid, the upgraded Roomba j7+ Combo, for $799. In both cases, you can enter the coupon code ENGROOMBA200 to receive the $200 discount exclusively for Engadget readers.

The Roomba j7+ includes a bundled cleaning station and iRobot’s poop detection tech. The company says the vacuum’s advanced sensors will avoid pet feces — and its “Pet Owner Official Promise” (P.O.O.P.) policy assures you it will replace the device for free if it runs over pet waste within its first year. The self-emptying vacuum also includes an intelligent mapping feature that lets you choose which rooms it covers, and you can schedule multiple cleanings per day in advance. The Roomba j7+ is usually $800, so its $549 discounted price (with code ENGROOMBA200) is worth noting if you’ve been on the lookout for a cleaning machine.

Wellbots’ coupon also applies to that model’s upgraded sibling, one of Engadget’s picks for the best robot vacuums. The Roomba j7+ Combo takes the j7+’s base features (including self-emptying tech and poop detection) and adds wet mopping, letting you transition seamlessly between carpet and floor cleaning. (It can do both simultaneously on hard floors.) It also includes a feature that can help keep your rugs dry by lifting the mop out of reach when it detects it’s on a carpet. The j7+ Combo typically costs $1,100.

Both devices work with the iRobot mobile app. It lets you manage the devices’ smart mapping capabilities, remote startup and scheduling. We find the app to be simple, intuitive and a significant selling point for Roomba robot cleaners.

Robosen announced a new auto-converting Transformer today. After launching its self-transforming Optimus Prime in 2021, the company set its sights on Grimlock, the Autobot-allied leader of the Dinobots who changes from a robot into a mechanical T-Rex. However, its $1,699 sticker price (a mere $1,499 for pre-orders) also allows it to transform your finances for the worse.

The Grimlock collectible stands 15 inches tall in robot mode and 15.4 inches in dinosaur mode. Robosen describes its auto-transforming as “the epitome of auto-conversion” while calling the product “the world’s first dual-form, bipedal walking robot.” (The Optimus Prime version walks as a robot but drives in truck form.) The manufacturer says Grimlock includes 85 microchips, 34 high-precision intelligent servos while running on “advanced SOC chip technology” and “a comprehensive robot operating system.” In addition, it has six-axis IMU sensors for balance monitoring.

This Grimlock is based on the Transformers G1 version, which debuted in 1985. The collectible includes the original toy’s Energon sword, galaxial rocket launcher, and crown accessories. Robosen and Hasbro even brought back the original voice actor from the G1 animated series, the now 72-year-old Gregg Berger, to record “150+ original Generation 1 Transformers audio lines” for the expensive toy. For the uninitiated, the character is known for a simplistic speaking style, including the well-trodden phrase, “Me Grimlock!”

Robosen / Hasbro

In addition to hearing Grimlock’s classic voice (synchronized with “robotic actions”), you can also control it by speaking to it. The product recognizes 42 voice commands, letting you tell it to transform, walk and perform various “stunning stunts.” You can also create new poses and actions for the Dinobot using four programming modes (block-based, manual, voice and computer-based). And if money truly is no object, you can pair it with the $699 Optimus Prime robot to watch them reenact your favorite classic Transformers battle scenes. This would be wonderful for children, but its pricing mostly limits it to nostalgia-stricken adults with more money than meets the eye.

The Grimlock auto-converting robot is available for pre-order now from Robosen and Hasbro. It’s expected to ship in late fall. Although its pricing may be a tough sell, at least they’re throwing in a limited edition collector’s coin so you can demonstrate that you spent the equivalent of a month’s rent on a robotic T-Rex that speaks about itself in the third person.

Chipotle isn't done experimenting with robots that could make life easier for restaurant staff. The chain has teamed up with robotics company Vebu to test a prototype Autocado robot (yes, that's the name) that cuts, cores and peels avocados to be used in guacamole. Kitchen workers only have to fill the bot with up to 25lbs of ripe avocados and choose a size. After the processing is done, they collect the fruit in a bowl, add remaining ingredients and start mashing.

As Autocado improves, Chipotle expects to cut guacamole prep time in half — no mean feat when it usually takes 50 minutes to make a batch. That could ensure a steady supply of guac while eliminating some of the drudgery for employees. The restaurant also believes the robot could reduce food waste (and thus costs) through more efficient processing.

Autocado is currently limited to a testing center in Irvine, California. This is the start of a "long term partnership" with Vebu, Chipotle adds. The two haven't said what comes next, but the focus will be on collaborative robots that "drive efficiencies" and "ease pain points" for workers. Last year, Chipotle began testing Miso Robotics' Chippy robot to aid in making tortilla chips.

Chipotle is far from alone. McDonald's and other restaurants are trying AI, robots and other automated solutions to streamline their experiences. These moves theoretically help employees concentrate on serving customers and other tasks where humans are still preferable. Of course, there are also lingering concerns among critics that restaurants might use this to automate people out of jobs. They may choose to shrink headcounts and cut costs instead of easing the workload. That isn't guaranteed to happen with Autocado when humans are still necessary, but the long-term future isn't quite so clear.

It's always a good idea to look for discounts on big-ticket items on Prime Day, and robot vacuums are no exception. These machines can be some of the most expensive gadgets you buy for your home, with high-end models costing close to (or more than) $1,000 normally. Thankfully, Prime Day is a good time to pick up a robo-vac for much less than that since premium models tend to be hundreds of dollars off, and even those that already have budget-friendly prices are also often discounted. Here are the best robot vacuum Prime Day deals we could find on all of our favorite machines.

iRobot Roomba 694

The iRobot Roomba 694 has dropped to $199 for Prime Day. It's normally our favorite budget robot vacuum, so this discount makes it an even better buy. We like its minimalist yet attractive design, strong suction power and easy-to-use companion app.

iRobot Roomba s9+

The premium Roomba s9+ is on sale for $600 for Prime Day. This is the most expensive robot vacuum that iRobot makes, and it's currently one of our favorite high-end models. It might be overkill for most people, but it's a robo-vac that does an excellent job of cleaning both hard and carpeted floors, and doesn't choke up at the first sign of pet hair. We also like that it comes with a clean base into which it will empty its dustbin after every job.

iRobot Roomba j7+

The iRobot Roomba j7+ has been discounted to $649 for Prime Day. This is one of the company's newest robot vacuums and we like that it has strong suction power and comes with a clean base. The j7+'s claim to fame, though, is its advanced obstacle avoidance, which helps it steer clear of furniture and other objects while it's cleaning. This includes a robo-vac's arch nemesis — pet poop.

Shark AI Ultra 2-in-1 robot vacuum

Shark's vacuum-and-mop machine has dropped to $380 for Prime Day. It's one of the best robot vacuums you can get right now because of its versatility and decent starting price, so if you can pick it up while it's on sale, that's even better. It comes with a water reservoir with a cloth attached to it that lets you mop hard floors when you need to. The standard dustbin will hold all debris during vacuuming, and the machine is smart enough to empty its clean base automatically after every vacuuming job (you'll have to empty the water reservoir on your own).

Shark AI Ultra robot vacuum

A top pick in our robot vacuum guide, Shark's AI Ultra robo-vac is on sale for $419 for Prime Day. It's just as easy to use and effective as a similar Roomba, but you can often find it at a notably cheaper price point. We found that it cleaned carpet and hard floors well, and its included clean base is bagless, which means you won't have to spend more money over time buying proprietary garbage bags for it.

Anker Eufy RoboVac X8 Hybrid

Another vac-and-mop combo, the Eufy RoboVac X8 Hybrid has dropped to $300 for Prime Day. Like a lot of other Anker/Eufy devices, the RoboVac X8 Hybrid already starts out much cheaper than its competition but it works nearly just as well. It can vacuum and mop, thanks to its included water reservoir, and we were impressed by its easy set-up process, four cleaning modes, smart home mapping and handy "tap-and go" feature.

Shark makes some of the best robot vacuums around and you can currently save quite a bit on a self-emptying model. The device is 50 percent off as it has dropped to $300 at Amazon. That's the lowest price we've seen for it to date.

Robot vacuums are an excellent quality of life upgrade for many people compared with having to clean floors manually with a standard vacuum. Shark's RV1001AE model has several features that make it a strong option. It has a bagless, self-emptying base that Shark says can hold up to 45 days worth of muck. You won't need to buy disposal bags like you would with other models.

The vacuum is able to map out your home. You can schedule cleanings for your entire home or ask the robot to take care of a certain room or area immediately using the SharkClean app, Alexa or Google Assistant.

Shark says the vacuum has powerful suction as well as a self-cleaning brushroll that can pull debris and hair from carpets and hardwood floors. The Shark IQ Robot uses a row-by-row cleaning method. When it's done, it returns to its dock to recharge.

The spotted lanternfly may look innocent, but these ravenous creatures have been known to decimate crops, causing more than $500 million in damages to various fruit trees since being accidentally introduced to this country nearly a decade ago. The big idea right now is to introduce several species of wasps into the mid-atlantic ecosystem to hunt and eat the lanternflies, but students at Carnegie Mellon University's Robotics Institute have developed an alternative plan in the form of a robot death machine.

It’s called TartanPest and uses a combination of technologies and components to autonomously hunt down and destroy lanternfly egg masses. It starts with an electric tractor for movement and a suite of cameras for traversal. This computer vision is also constantly on the hunt for egg masses, containing up to 50 lanternfly eggs. Once it finds a mass on a tree, rock or even a rust metal surface, a robot arm with a spinning brush attachment goes in for the kill, scrubbing the eggs away like so much trash.

"Currently, spotted lanternflies are concentrated in the eastern portion of the nation, but they are predicted to spread to the whole country," said Carolyn Alex, an undergraduate researcher on the TartanPest team. "By investing in this issue now, we will be saving higher costs in the future."

There’s some deep-learning algorithms at work here to locate the egg masses, trained using a large image data set. The robot does work autonomously but requires a human on-hand to fix any issues as they arise. So it’s probably not the most efficient way to eradicate spotted lanternflies. Still, it’s pretty darned cool and everybody loves a good killer robot.

This is just a prototype design for now, as the team designed the construct as part of Farm-ng's 2023 Farm Robotics Challenge. In other words, if lanternflies are getting you down, you have a while to wait before you can unleash an army of killer robots. In the meantime, you can always try an army of killer wasps instead.
