iRobot is going outdoors with an autonomous Roomba lawn mower with smart mapping tech
Mowing the lawn can quickly get in the way of summer fun, just like vacuuming and mopping interfere with just about anything else you might rather be doing. Never fear, iRobot, the company that brought you the Roomba robotic vacuum cleaner and Braava electronic mop, has been listening. Yesterday, the robotic chore solution company announced its launch of Terra, an intelligent lawn mower ready to do your outdoor bidding. According to iRobot’s press release, it will be on sale in Germany and the US, the latter being through a beta program only; however, no exact release date has been provided.
To accomplish its yard travels, iRobot’s Imprint Smart Mapping technology, which is arguably one of the features that made Roomba so popular, has been incorporated into Terra’s functionality. The new grass buster also has some other convenience features in common with its indoor cousins: It recharges on its own by returning to a docking base and can be controlled via an app on either a smartphone or digital assistant. For its more unique features, Terra’s designers relied on the current masters of lawn care for inspiration: humans.
Rather than follow any sort of random get-it-done movement path a Roomba might follow to clean a floor, Terra has a preprogrammed pattern modeled after the straight, back-and-forth lines typically used for mowing. If the battery is running low, the robot returns to its base to recharge, picking up where it left off until its task is complete. The grass cut length is also programmable for heights of about 1″ to about 2.5″, but it should be noted that Terra’s function focus being on maintenance over heavy cut jobs.

The weather isn’t lost on this outdoor helper, either. Terra has been designed with rugged features so that rainy conditions – and by extension, tough terrain – will not prevent it from doing its job. As for grass clippings? There aren’t any or at least any that need to be hauled off to the trash like classic lawn mowers. Sliced blades of grass are refined into tiny mulch bits that double as fertilizer.
Of course, iRobot isn’t the first company to venture into automated lawn maintenance solutions. Swedish manufacturer Husqvarna’s Automower robotically maintains lawns using frequent trips around a programmed area, naturally fertilizes soil with miniscule clippings, mows any time of day and in inclement weather, resists theft with a built-in alarm, and is controlled via app using smartphone or digital assistant. It uses an installed boundary line for yard area detection, however, making set-up more complicated than regular operation. German outdoor product manufacturer GARDENA and Wisconsin-based McCullough Motors have their own lawn robots as well – the SILENO and ROB R1000, respectively, with similar features as well as a required boundary line.
After a survey of the lawn robot market, iRobot took aim to eliminate costly and labor-intensive ground wiring which is required to operate other auto mowers. For Terra, the company developed a wireless communications system incorporating standalone beacons, enabling users to simply program their lawn’s boundary line after placing the beacons around their yard. The intelligent detection software developed by iRobot for its other robotic household helpers combined with a simpler installation process may just give the company an edge over its established competitors in the lawn bot arena.

Tesla confirms that it finally solved its 4680 battery’s dry cathode process
The suggests the company has finally resolved one of the most challenging aspects of its next-generation battery cells.
Tesla has confirmed that it is now producing both the anode and cathode of its 4680 battery cells using a dry-electrode process, marking a key breakthrough in a technology the company has been working to industrialize for years.
The update, disclosed in Tesla’s Q4 and FY 2025 update letter, suggests the company has finally resolved one of the most challenging aspects of its next-generation battery cells.
Dry cathode 4680 cells
In its Q4 and FY 2025 update letter, Tesla stated that it is now producing 4680 cells whose anode and cathode were produced during the dry electrode process. The confirmation addresses long-standing questions around whether Tesla could bring its dry cathode process into sustained production.
The disclosure was highlighted on X by Bonne Eggleston, Tesla’s Vice President of 4680 batteries, who wrote that “both electrodes use our dry process.”
Tesla first introduced the dry-electrode concept during its Battery Day presentation in 2020, pitching it as a way to simplify production, reduce factory footprint, lower costs, and improve energy density. While Tesla has been producing 4680 cells for some time, the company had previously relied on more conventional approaches for parts of the process, leading to questions about whether a full dry-electrode process could even be achieved.
4680 packs for Model Y
Tesla also revealed in its Q4 and FY 2025 Update Letter that it has begun producing battery packs for certain Model Y vehicles using its in-house 4680 cells. As per Tesla:
“We have begun to produce battery packs for certain Model Ys with our 4680 cells, unlocking an additional vector of supply to help navigate increasingly complex supply chain challenges caused by trade barriers and tariff risks.”
The timing is notable. With Tesla preparing to wind down Model S and Model X production, the Model Y and Model 3 are expected to account for an even larger share of the company’s vehicle output. Ensuring that the Model Y can be equipped with domestically produced 4680 battery packs gives Tesla greater flexibility to maintain production volumes in the United States, even as global battery supply chains face increasing complexity.

Tesla Giga Texas to feature massive Optimus V4 production line
This suggests that while the first Optimus line will be set up in the Fremont Factory, the real ramp of Optimus’ production will happen in Giga Texas.
Tesla will build Optimus 4 in Giga Texas, and its production line will be massive. This was, at least, as per recent comments by CEO Elon Musk on social media platform X.
Optimus 4 production
In response to a post on X which expressed surprise that Optimus will be produced in California, Musk stated that “Optimus 4 will be built in Texas at much higher volume.” This suggests that while the first Optimus line will be set up in the Fremont Factory, and while the line itself will be capable of producing 1 million humanoid robots per year, the real ramp of Optimus’ production will happen in Giga Texas.
This was not the first time that Elon Musk shared his plans for Optimus’ production at Gigafactory Texas. During the 2025 Annual Shareholder Meeting, he stated that Giga Texas’ Optimus line will produce 10 million units of the humanoid robot per year. He did not, however, state at the time that Giga Texas would produce Optimus V4.
“So we’re going to launch on the fastest production ramp of any product of any large complex manufactured product ever, starting with building a one-million-unit production line in Fremont. And that’s Line one. And then a ten million unit per year production line here,” Musk stated.
How big Optimus could become
During Tesla’s Q4 and FY 2025 earnings call, Musk offered additional context on the potential of Optimus. While he stated that the ramp of Optimus’ production will be deliberate at first, the humanoid robot itself will have the potential to change the world.
“Optimus really will be a general-purpose robot that can learn by observing human behavior. You can demonstrate a task or verbally describe a task or show it a task. Even show it a video, it will be able to do that task. It’s going to be a very capable robot. I think long-term Optimus will have a very significant impact on the US GDP.
“It will actually move the needle on US GDP significantly. In conclusion, there are still many who doubt our ambitions for creating amazing abundance. We are confident it can be done, and we are making the right moves technologically to ensure that it does. Tesla, Inc. has never been a company to shy away from solving the hardest problems,” Musk stated.

Rumored SpaceX-xAI merger gets apparent confirmation from Elon Musk
The comment follows reports that the rocket maker is weighing a transaction that could further consolidate Musk’s space and AI ventures.
Elon Musk appeared to confirm reports that SpaceX is exploring a potential merger with artificial intelligence startup xAI by responding positively to a post about the reported transaction on X.
Musk’s comment follows reports that the rocket maker is weighing a transaction that could further consolidate his space and AI ventures.
SpaceX xAI merger
As per a recent Reuters report, SpaceX has held discussions about merging with xAI, with the proposed structure potentially involving an exchange of xAI shares for SpaceX stock. The value, structure, and timing of any deal have not been finalized, and no agreement has been signed.
Musk appeared to acknowledge the report in a brief reply on X, responding “Yeah” to a post that described SpaceX as a future “Dyson Swarm company.” The comment references a Dyson Swarm, a sci-fi megastructure concept that consists of a massive network of satellites or structures that orbit a celestial body to harness its energy.
Reuters noted that two entities were formed in Nevada on January 21 to facilitate a potential transaction for the possible SpaceX-xAI merger. The discussions remain ongoing, and a transaction is not yet guaranteed, however.
AI and space infrastructure
A potential merger with xAI would align with Musk’s stated strategy of integrating artificial intelligence development with space-based systems. Musk has previously said that space-based infrastructure could support large-scale computing by leveraging continuous solar energy, an approach he has framed as economically scalable over time.
xAI already has operational ties to Musk’s other companies. The startup develops Grok, a large language model that holds a U.S. Department of Defense contract valued at up to $200 million. AI also plays a central role in SpaceX’s Starlink and Starshield satellite programs, which rely on automation and machine learning for network management and national security applications.
Musk has previously consolidated his businesses through share-based transactions, including Tesla’s acquisition of SolarCity in 2016 and xAI’s acquisition of X last year. Bloomberg has also claimed that Musk is considering a merger between SpaceX and Tesla in the future.
