TLDR
- Humanoid robots are advancing rapidly with AI, with companies like Tesla planning to produce thousands of Optimus robots by year-end
- Companies are developing robots for various purposes including household chores (NEO Gamma), companionship (Aria from Realbotix), and industrial applications
- Major tech companies including Amazon, Google, Microsoft, Nvidia, Tesla, Meta, and Apple are investing in humanoid robotics
- Despite progress, practical humanoid robots face challenges including high costs ($50,000-$60,000), short battery life, overheating issues, and safety concerns
- Experts suggest widespread adoption of reliable humanoid robots may take decades to become reality
Silicon Valley’s biggest names are investing heavily in humanoid robots, fueled by recent advances in artificial intelligence. While impressive demonstrations showcase robots that can walk, perform chores, and even mimic human interactions, experts caution that practical, affordable robots for everyday use remain years away.
Tesla CEO Elon Musk announced plans to produce “several thousand” Optimus robots by the end of this year. At a recent panel, Musk expressed optimism about the technology, stating he expects humanoid AI robots to unlock “quasi-infinite products and services.”
Recent demonstration videos show Tesla’s Optimus robots walking and scanning rooms for obstacles. Other companies are making strides as well. California-based Clone Robotics released footage of its Protoclone synthetic humanoid robot last week, showing a machine built with over 1,000 artificial “myofibers” – mesh tubes filled with air that contract to create movement.
Silicon Valley robotics company 1X Robotics is targeting the home market with its NEO Gamma robot. In a promotional video released Friday, the robot is shown carrying laundry, operating a vacuum, and collecting packages from delivery personnel. According to the company’s website, NEO Gamma is specifically designed for household tasks and home management.
Some robots are being developed for companionship rather than utility. At the 2025 Consumer Electronics Show last month, tech publication CNET interviewed “Aria,” an AI-powered humanoid robot from Realbotix. Described as a “digital girlfriend,” Aria is designed for “companionship and intimacy” according to statements made by the robot during the interview.
The industry’s biggest players are all investing in the humanoid robot space
The tech industry’s biggest players are all investing in the humanoid robot space. Amazon, Google, Microsoft, Nvidia, and Tesla have publicly announced robotics initiatives. According to Bloomberg, Meta and Apple have also begun funding or developing humanoid robotics systems.
These companies see numerous potential applications for humanoid robots. They could be deployed in factories to address labor shortages, assist in elder care, or perform dangerous tasks that would put humans at risk.
University of Michigan robotics professor Chad Jenkins highlights the potential benefits for healthcare: “We have such a huge need for labor, for taking care of our aging and disabled populations. It really is such a huge cost to provide that care, and we can’t provide it to everybody.”
However, creating effective humanoid robots presents major technical challenges. One key hurdle is training robots to understand when and how they can interact with objects – a concept called “affordance.”
“Affordance basically says, whenever I see my mug, I know I can grab that handle, and then I can take a sip out of it or pour out of it,” explained Jenkins. Teaching robots these skills requires massive amounts of data and training.
There are currently three main approaches to training robots. The first is through teleoperation, where a person wears specialized equipment to perform tasks while the robot mimics their movements. The second uses computer simulations to create virtual training scenarios. The third combines both real-world human movements and simulations.
At CES 2025 in January, Nvidia CEO Jensen Huang demonstrated his company’s approach to teaching robots via simulations called Nvidia Cosmos. This method allows for testing many scenarios without risking damage to expensive robot prototypes.
Pulkit Agrawal, associate professor at MIT, explains that simulations have limitations: “The simulation is different from the real world. You have to bridge that gap. And some things are still hard to simulate like clothes and things which are deformable, things which are soft.”
Costs Ranging from $50,000 to $60,000
Beyond training challenges, current humanoid robots face practical limitations. They’re expensive, with costs running from $50,000 to $60,000 despite some companies claiming lower price points. They also have short battery life and tend to overheat, limiting their operational time.
“If a humanoid robot falls down at home, one thing is the cost to repair, the other is the safety of the humans in the home,” noted Ye Zhao, an assistant professor at Georgia Tech. “The reliability of humanoid robots still needs a lot of work.”
MIT’s Agrawal is blunt about the current state of the technology: “There isn’t a humanoid hardware that you can buy and say it’s reliable. That simply doesn’t exist today.” Current models may run for only 30 minutes to an hour before needing to recharge or cool down.
Despite these challenges, development continues at a rapid pace. The potential market for capable humanoid robots is enormous, spanning industrial, commercial, and consumer applications. For now, though, the closest most homes will get to a robot helper remains the humble Roomba vacuum cleaner.
Silicon Valley’s enthusiasm for humanoid robots reflects the technology’s long-term promise, but the gap between today’s demonstrations and tomorrow’s reliable, affordable robots remains substantial.
