Tesla has offered a look at the latest version of its Optimus robot. In a new video, the second-gen humanoid machine appears to have greater dexterity than its predecessor, though you’ll likely have to wait quite a while longer before you can pick up one of these to help around the house. Milan Kovac, who works on the Optimus project, noted on X that the footage is in real-time and that there was no CGI involved.

While the previous version of Optimus struggled to walk during a live demo, the latest model is able to move with more grace, perhaps thanks to its Tesla-designed actuators and sensors. The machine has an actuated neck with two degrees of freedom and it's said to be 30 percent faster at walking while mimicking the geometry of human feet.

The second-gen Optimus has a sleeker design and Tesla says it has been able to reduce the weight of the robot by 10 kilograms without sacrificing any functionality. The company claims this model has improved balance and full-body control — it's shown squatting and getting back up in the video.

Among the biggest upgrades are to the hands. Tesla says these now have 11 degrees of freedom and they can move more quickly. Optimus is able to handle objects more delicately, as shown by a demo of it picking up and gently placing down an egg. These all seem like marked improvements over the last iteration of Optimus, which we first saw in September last year.

While the robot looks mechanically more impressive than its predecessor, that's only one piece of the puzzle, as Electrek points out. If the robot is to be used in the real world as a "general purpose, bi-pedal, humanoid robot capable of performing tasks that are unsafe, repetitive or boring" (as Tesla is aiming for), it will need to have a robust artificial intelligence that allows it to operate safely and independently. 

That's likely many years away from becoming a reality, particularly when Tesla has had problems with the AI features of its cars. In fact, the company just recalled nearly every car it has shipped in the US to fix issues with the Autopilot system.

It's no secret that robot vacuums are some of the most expensive gadgets you can get for your home. But Black Friday robot vacuum deals make it a bit easier to grab one, and this year is no different. A handful of machines from Shark and iRobot have dropped to record low prices for Black Friday, including a few of our favorite models. You can snag a Roomba for as low as $159, which is one of the best prices we've seen all year.

But before making a purchase, we recommend thinking about the type of home you have and how you'll use the machine: do you have carpet or mostly hard flooring? Do you have pets who shed constantly? Do you want a combo vacuum-and-mop machine? Once you have those details settled, check out the best deals on robot vacuums for Black Friday 2023 below.

iRobot Roomba 694

The Roomba 694 is on sale for $159 in this Black Friday vacuum deal.

Black Friday is a great time to pick up big-ticket items while they're deeply discounted, and robot vacuums fit that bill this year. It's not hard to drop hundreds on an autonomous dirt-sucker at any other time of the year, but Black Friday deals have discounted a bunch of our favorite models. Before snagging a deal, think about the type of home you have and how you'll use the machine: do you have carpet or mostly hard flooring? Do you have pets who shed constantly?

Researchers at the Zurich-based ETH public university, along with a US-based startup affiliated with MIT, have done the impossible. They’ve printed a robot hand complete with bones, ligaments and tendons for the very first time, representing a major leap forward in 3D printing technology. It’s worth noting that the various parts of the hand were printed simultaneously, and not cobbled together after the fact.

Each of the robotic hand’s various parts were made from different polymers of varying softness and rigidity, using a new laser-scanning technique that lets 3D printers create “special plastics with elastic qualities” all in one go. This obviously opens up new possibilities in the fast-moving field of prosthetics, but also in any field that requires the production of soft robotic structures.

Basically, the researchers developed a method to 3D print slow-curing plastics, whereas the technology was previously reserved for fast-curing plastics. This hybrid printing method presents all kinds of advantages when compared to standard fast-cure projects, such as increased durability and enhanced elastic properties. The tech also allows us to mimic nature more accurately, as seen in the aforementioned robotic hand.

“Robots made of soft materials, such as the hand we developed, have advantages over conventional robots made of metal. Because they’re soft, there is less risk of injury when they work with humans, and they are better suited to handling fragile goods,” ETH Zurich robotics professor Robert Katzschmann writes in the study.

This advancement still prints layer-by-layer, but an integrated scanner constantly checks the surface for irregularities before telling the system to move onto the next material type. Additionally, the extruder and scraper have been updated to allow for the use of slow-curing polymers. The stiffness can be fine-tuned for creating unique objects that suit various industries. Making human-like appendages is one use case scenario, but so is manufacturing objects that soak up noise and vibrations. 

MIT-affiliated startup Inkbit helped develop this technology and has already begun thinking about how to make money off of it. The company will soon start to sell these newly-made printers to manufacturers but will also sell complex 3D-printed objects that make use of the technology to smaller entities. 

iRobot's Roomba Combo j5+ robot vacuum is $300 off in an early Black Friday deal via Wellbots. This is a record-low for the appliance, dropping the price to $500 instead of the MSRP of $800. In the past, discounts for the j5+ stalled at around $200 off. As typical with Wellbots deals, there’s a promo code. Just enter “ENGBF300” at checkout and you’ll be good to go.

The Roomba Combo j5+, as the name suggests, is a combination unit that includes both a vacuum and a mopping feature. It can pinpoint no-mop zones, so you don’t have to worry about the robot spraying fluid all over your brand-new carpet. The j5+ can also avoid more than 80 common floor obstacles. As a matter of fact, iRobot will replace the unit for free if it doesn’t avoid pet waste, as part of the company’s “P.O.O.P.” pledge. No, we didn’t make that up. It stands for “Pet Owner Official Promise.”

This is a well-regarded robovac with one obvious downside when compared to pricier models like the Roomba j7+ and the flagship j9+. Despite the combo functionality, you have to manually swap out the bins when switching between vacuuming and mopping. The more expensive robots do this automatically. Still, the j9+ costs $900 and the j5+ is currently on sale for $400. You’ll have to decide if that automation feature is worth the price difference.

Wellbots is also selling the junior-grade Roomba 694 vacuum for $115 off. Just enter “ENGBF115” and grab it for $159. This is your basic workhorse robovac with no mopping functionality. It does one job and it does it well, which is why it ended up on our lists of the best robot vacuums for 2023 and the best budget robot vacuums.

The use for humans in the world of robotics, even as teachers, is shrinking thanks to AI. NVIDIA Research has announced the creation of Eureka, an AI agent powered by GPT-4 that has trained robots to perform tasks using reward algorithms. Notably, Eureka taught a robotic hand to do pen spinning tricks as well as a human can (honestly, as you can see in the YouTube video below, better than many of us).

Eureka has also taught quadruped, dexterous hands, cobot arms and other robots to open drawers, use scissors, catch balls and nearly 30 different tasks. According to NVIDIA Research, the AI agent's trial and error-based reward programs are 80 percent more effective than those written by human experts. This shift meant the robots' performance also improved by over 50 percent. Eureka also self-evaluates based on training results, instructing changes in reward functions as it sees fit.

NVIDIA Research has published a library of its Eureka algorithms, encouraging others to try them out on NVIDIA Isaac Gym, the organization's "physics simulation reference application for reinforcement learning research."

The idea of robots teaching robots is seeing increased interest and success. A May 2023 paper published in the Transactions on Machine Learning Research journal presented a new system called SKILL (Shared Knowledge Lifelong Learning), which allowed AI systems to learn 102 different skills, including diagnosing diseases from chest X-rays and identifying species of flowers. The AIs shared their knowledge — acting as teachers in a way — with each other over a communication network and were able to master each of the 102 skills. Researchers at schools like MIT and the University of Bristol have also had success, specifically in using AI to teach robots how to manipulate objects.

If you've been looking to buy a robot vacuum for yourself, or you know someone who would love to receive one as a gift this holiday season, Amazon's October Prime Day has a number of deals you'll want to check out. Big sale events like this one are a good time to shop for big-ticket items like robot vacuums, because you can usually find premium models at close to record-low prices. And affordable models aren't excluded either, so you could pick up a budget-friendly robot vacuum for even less. Here are the best robot vacuum deals we found for October Prime Day.

iRobot Roomba 694

iRobot's Roomba 694 has dropped to $199 for Prime Day. It's our favorite cheap robot vacuum thanks to its strong suction power, attractive design and easy to use app. It'll be a good option for robo-vac novices, or anyone that doesn't want to fuss too much with an automatic dirt sucker. It clears hard and carpeted floors well, and it automatically returns to its base once a cleaning job is finished so it can recharge.

iRobot Roomba s9+

The premium Roomba s9+ is on sale for $600 right now, if you have Prime. It's the most expensive model that iRobot makes, and it's currently one of our favorite high-end robo-vacs. Most people don't need something this advanced, but it's hard to deny how well this machine sucks up dirt and debris, and it doesn't choke up at the first sign of pet hair either. It also comes with a self-emptying base, so when it returns after each job to recharge, it will empty its dustbin into the base — no human interaction required.

Shark 2-in-1 robot vacuum and mop

Shark's 2-in-1 robot vacuum and mop machine is on sale for $400 right now, which is nearly half off its regular price. If you're looking for a robot that can thoroughly vacuum and give hard floors a good scrub with water and cleaning solution, this is a good pick. As a vacuum, it has strong suction power and decent obstacle avoidance. As a mop, it uses its reservoir and attached cloth to get rid of messier grime and stains. It also comes with a self-emptying base for the vacuum only that the machine will empty its dustbin into after every vacuuming job.

Shark AI Ultra robot vacuum

One of our favorite robot vacuums at the moment, Shark's AI Ultra is on sale for $403. 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. It cleans hard and carpeted floors well, and it has a bagless, self-emptying base, which is great because you will not have to continuously purchase proprietary bags over time to keep using it.

Ancient, vine-draped monuments and towering obelisks protrude from the forest floor, connected by a maze of stone paths and one hyper-speed transit capsule. Statues loom among the monoliths: hooded human figures and mythological beasts surrounded by saintly geometry in gold and turquoise. I’m running down an overgrown platform by the water, sun radiating off the side of my face, trying to find the next puzzle. I take a sharp turn, the shadows shift and my silhouette is suddenly projected in front of me: waist on a slim pivot, hip joints jutting out, sticklike arms. I remember I’m made of metal and wires, and for a brief moment, I’m surprised. I forgot — I’m a robot.

The Talos Principle 2 reintroduces a post-apocalyptic world filled with the puzzles and dreams society left behind, and populates it with a race of machines who simultaneously worship humans and consider themselves to be the natural evolution of humanity. The game’s first quarter, which spans roughly seven hours, offers a beautiful and immersive playground of puzzle solving and philosophical inquiry, and it feels both grander and more cohesive than the original Talos Principle. That game came out in 2014 and featured a lone robot in an AI-powered testing ground. The sequel features an entire society of sentient machines. It also has lots of laser-powered, logic-based spatial puzzles, of course.

Croteam

The Talos Principle 2 is set in a futuristic society of robots, and you’re the 1,000th machine to come off the line. There’s debate among the citizens about whether you should be the final addition to the group, as one of its founders once dictated, and your presence unlocks a new prophecy tied to a mysterious island. Elohim, the AI antagonist of the first game, has calmed down significantly and acts as a caretaker to the robots, gently guiding their sleep cycles with a booming voice.

Each robot has its own personality, and it doesn’t take long for these machines to feel fully human, despite their lack of meat and bones. Developers at Croteam took the time to build out backstories and individual points-of-view for each supporting character, and their conversations and arguments flow seamlessly. The Talos Principle 2 features full voice acting and branching dialogue trees with multiple meaningful responses for players to choose from. It’s not uncommon to see six to eight options in conversations, presenting discrete approaches to heavy prompts about faith, doubt, consciousness, life, death and love. This is a game for curious minds, and the dialogue system supports this with rich character development and high-quality conversational writing.

Croteam

This robot society provides the narrative framework for actual gameplay. On the mysterious, prophesied island players encounter a series of puzzles hidden among humanity’s ruins, much like in the original game. The structures on the island are widespread and vast, but navigation is intuitive, thanks to subtle environmental cues, a compass with waypoints and directions from the other robots on the expedition team. This time around, you’re not alone (no offense, Elohim).

The puzzles themselves are devilish. They start simply, prompting players to divert laser beams into portals of the same color using connector rods, jammers, blocks, pressure pads and fans. As players progress through the riddle rooms, the game introduces new tools, like a drill that can create holes in some walls and an inverter that reverses the laser color, adding unexpected complexity to the puzzles. It’s my firm belief that the best puzzles in video games are ones that appear simple, but have a single, incredibly tricky solution buried beneath layers of almost-there answers. Nothing beats that breakthrough feeling when the entire room suddenly makes sense, the lasers align, and all the right doors slide open. The beginning hours of The Talos Principle 2 effortlessly capture this sensation, again and again.

Tetrominoes are back in the sequel, and they’re big. Not only metaphorically (the robots often theorize about the shapes’ supposed purpose), but also in physical size. I made literal bridges out of building-sized tetrominoes, swapping out pieces and rotating them on a grand scale. While this segment wasn’t particularly challenging, it was satisfying in a new kind of way.

Croteam

In its first quarter, The Talos Principle 2 reproduces the brilliance of the original game and adds to this foundation, expanding its world narratively and mechanically. Philosophical conversations are no longer siloed in read-only terminals, though there are still datasets scattered around the map. The story’s main prompts are instead integrated into gameplay via deep, player-driven conversations with NPCs, and even a little bit of light gossip. The Talos Principle 2 has secrets to discover, personalities to explore and questions to answer — and that’s all on top of being a uniquely fantastic (and optimistic) sci-fi puzzle game.

Footage captured by a food delivery robot in Los Angeles was used to arrest and convict two people after a failed attempt to steal it off the street earlier this year, according to 404 Media. Serve Robotics, which works with Uber Eats for last-mile deliveries in the area, shared videos of the incident with the Los Angeles Police Department both proactively and after a subpoena. Serve previously met with LAPD to “open a line of communication” between the two ahead of any potential troubles, emails obtained by 404 also show.

It comes at a time when public wariness around the technology is already high, with concerns about just how much the robots are recording and where that footage ultimately goes. Serve Robotics CEO Ali Kashani boasted about the resulting convictions on social media, tweeting, “Some genius once tried to steal one of our robots… It didn’t end well (for them).” In a follow-up blog post, Kashani takes a softer stance, attempting to explain how the company balances its approach to involving law enforcement with its responsibility to the public and fostering trust.

The company’s principles, according to Kashani, include “not using robots for surveillance or other purposes that violate the public’s sense of privacy,” and not putting unnecessary strain on public resources by calling in the police “to address every minor incident of robot vandalism.” In this case, in which the police were immediately notified and arrests were made, the robot got away on its own and was, as Kashani describes it, “unharmed.” The company turned in all relevant footage before deleting it.

It remains unclear how long Serve keeps its robots’ recordings under normal circumstances, and its vagueness around the videos' potential use doesn’t inspire much confidence. In a statement to 404 Media, Serve’s head of communications, Aduke Thelwell, said it is the company’s policy to “regularly delete camera feed unless otherwise required, and to comply with subpoena requests.”

The New York Police Department (NYPD) is implementing a new security measure at the Times Square subway station. It's deploying a security robot to patrol the premises, which authorities say is meant to "keep you safe." We're not talking about a RoboCop-like machine or any human-like biped robot — the K5, which was made by California-based company Knightscope, looks like a massive version of R2-D2. Albert Fox Cahn, the executive director of privacy rights group Surveillance Technology Oversight Project, has a less flattering description for it, though, and told The New York Times that it's like a "trash can on wheels."

K5 weighs 420 pounds and is equipped with four cameras that can record video but not audio. As you can guess from the image above, the machine also doesn't come with arms — it didn't quite ignore Mayor Eric Adams' attempt at making a heart. The robot will patrol the station from midnight until 6 AM throughout its trial run that's running over the next two months. But K5 won't be doing full patrols for a while, since it's spending its first two weeks mapping out the station and roaming only the main areas and not the platforms. 

It's not quite clear if NYPD's machine will be livestreaming its camera footage, and if law enforcement will be keeping an eye on what it captures. Adams said during the event introducing the robot that it will "record video that can be reviewed in case of an emergency or a crime." It apparently won't be using facial recognition, though Cahn is concerned that the technology could eventually be incorporated into the machine. Obviously, K5 doesn't have the capability to respond to actual emergencies in the station and can't physically or verbally apprehend suspects. The only real-time help it can provide people is to connect them to a live person to report an incident or to ask questions, provided they're able to press a button on the robot. 

NYC is leasing K5 for around $9 an hour for the next two months. The mayor sounds convinced that's worth what the robot can do even though, as The Times notes, he recently ordered several agencies to reduce spending by 15 percent. "This is below minimum wage," he said. "No bathroom breaks, no meal breaks." Adams has a history of supporting the use of machines as police tools. Earlier this year, the mayor also announced that the NYPD will acquire two Digidog robots for $750,000 each for use in hostage and other critical situations. That's quite a reversal from the NYPD's decision in 2021 to cancel its lease on what was then known as Boston Dynamics' Spot after facing backlash for its use.
