Twenty-five years of the new millennium have passed and we’re still waiting for the futuristic world we were promised: Living in space, hover-cars, jet packs and extraterrestrial encounters.

However, one technology straight out of “The Jetsons” is tantalizingly close: humanoid robots. Even better, the field is being led by forward-thinking US companies, such as Agility Robotics and Tesla.

The new breed of bots resemble humans, stand upright and can fold shirts, answer doors, get you coffee and take over back-breaking and monotonous factory work.

“These robots can act, move and behave in ways that we’ve only ever dreamed of before,” Modar Alaoui, founder of the Humanoids Summit, told The Post, predicting we’d better get used to it: “They will get embedded into the fabrics of our everyday lives.”

For example, Alaoui says: “You’re going to pull up to the next fast-food place and you’ll see humanoids flipping your burgers and making fries. All the dangerous, boring, dull, mundane tasks will be done by machines. It’s just a very natural evolution to automation.”

Here are four of the most advanced you’re most likely to see or interact with soon:

Optimus, Created by Tesla’s AI and Robotics Division

Customers at the Tesla diner in Los Angeles already experienced robot service from Elon Musk’s Optimus.

This past July, CEO Musk’s bot — made by the company’s AI and Robotics Division and outfitted with its Grok AI — greeted customers by handing them popcorn.

Never one to shy away from hyperbole, Musk, has predicted that his Optimus robots will curb crime, eliminate poverty and even perform surgeries.

Following approval of his gigantic and much ballyhooed trillion dollar pay package, Musk vowed that his bot will be “the biggest product of all time, bigger than cell phones, bigger than anything.”

Judging from a recent video, the Optimus may lack the warm and fuzzy look of some competitors (it’s as metallic and hard edged as the company’s cars) but it looks like it will make an excellent domestic, factory worker or restaurant counter server.

The bots run off an AI chip and can walk at speeds of 5 miles per hour while carrying 45 pounds, according to Tesla. Videos show Optimus doing everything from waxing the floor to taking a person’s blood pressure, carrying boxes down steps, making pizza and building a “brother” robot.

Musk has reportedly put the cost of them in the range of $20,000 to $30,000.

NEO Gamma, Created by 1X Technologies

Who doesn’t want a robot to do the dishes, straighten up after the kids and scrub the bathroom?

1X Technologies, originally a Scandinavian company, but now with its headquarters in Silicon Valley, is answering that question. The company was founded in 2014 and specializes in developing AI-powered robotics.

The NEO Gamma robot, 1X’s most ambitious effort yet, stands 5’ 6” and is very much a humanoid – with camera-infused eyes behind a dark shield on a human shaped head, baring a striking resemblance to one of the suits worn by French electronic music duo Daft Punk. NEO Gamma’s body perfectly suits the futuristic look of its clothing.  

“Early adopters” are already ordering the bots for $20,000 with delivery anticipated for later in 2026.

Randy Howie, co-founder of New York Robotics, a non-profit that fosters robotic development in the New York area, believes that “the NEO Gamma, more than any others, is closest to getting into the home.”

While the robot is plenty advanced and brimming with artificial intelligence, it learns by doing and the idea is that through the trial and error of accomplishing tasks for early adopters, future Neo Gammas will learn how to be the robo-domestic of your dreams.

“There is a not-so-distant future where we all have our own robot helper at home,” 1X CEO Bernt Børnich told Dezeen.com.

Digit v4, created by Agility Robotics

Up and running in warehouses of companies including Amazon, the Digit v4 is a workhorse. Agility Robotics, which grew out of Oregon State University’s robotics lab, is founded by professors and grad students, and has been evolving since 2019. The Digit is designed to do one very specific thing: move plastic bins that hold products in a warehouse or factory. It’s the kind of job that grinds down humans and leaves us with aching backs. But it is no sweat for a robot.

Billed as the “world’s first commercially deployed humanoid robot,” the Digit V4 contains some 5,000 parts. Advanced artificial intelligence allows it to do not only what it is programmed for, but also to experience what is happening around it as well as to react on its own.

Agility has a factory in Oregon, where the robots are produced and programmed.

Tim Smith, a spokesperson for Agility, told The Post the Digit 4 “is the only humanoid robot currently working in warehouses and factories today.”

Because the Digit v4 is built to match a human body, factories do not need to be reconfigured to accommodate them.

How productive are the robots? “By the end of [2025],” said Smith, “commercially deployed Digit robots will have moved roughly 140,000” of the plastic bins.

Olaf, Created by Walt Disney Imagineering

Some humanoids work in factories; others perform tasks at home. Olaf brings to life the character of the same name from the Disney movie “Frozen,” and is designed to keep people amused and engaged.

Olaf does this not only through motion, but by talking and actually holding up its end of a conversation. This is especially cool when you consider that some Disney characters – including Mickey Mouse and Donald Duck – communicate through body language. Olaf not only talks, but he does it in the voice of the movie character he is representing, which starts to make the bot more human than human.

Amazingly, the self-walking Olaf was created in mere months by Walt Disney Imagineering, the company’s design and development lab.

“The team used a branch of artificial intelligence called reinforcement learning,” said Kyle Laughlin, senior vice president of R&D technology and engineering for Walt Disney. “It’s a process through which the robot practices in its environment but also figures out thousands of movements through streamlined computer simulations.” 

Then there is the realistic look of Olaf’s “snow” on its body which, said Laughlin, “moves differently than the hard shells of other robotic characters, and he can fully articulate his mouth, eyes, and removable carrot nose and arms.

Olaf creates, said Laughlin, “a truly one-of-a-kind experience.”

Olaf is about 35 inches tall, weighs 33 pounds and is about to begin interacting with guests on March 29 at Disneyland Paris, but prototypes have already set the internet ablaze, with fans posting takes on the snowman’s signature lines to him, such as writing: “Olaf, I need a warm hug.”
