The humanoid robot race is getting intense. Just last week, Xpeng showed off its IRON robot at a big event in China, and honestly, people couldn’t tell if it was a real person inside the suit. Someone had to actually unzip it to prove it was all robot.
At the same time, 1X is letting people preorder their NEO home robot. Tesla is also working hard to make more Optimus robots. We’re seeing three totally different ways to build robots that can really help people. Let me walk you through each one and help you understand which might be best.

The Robot Bodies: How They Look and Feel
Imagine trying to fit through a doorway or pick something up from a shelf. Robots need to work in spaces built for humans, so all three are roughly human-sized. But they’re built in very different ways.
Xpeng IRON is about 5’10” tall and weighs 154 pounds—basically like an average adult. What makes it special is that it’s designed to work like the human body works inside. It has a flexible spine, muscles that can stretch and squeeze, and 62 active joints. It can shrug, twist, and keep its balance on uneven ground. The hands are really important too—each one can move 22 different ways, so it can pick up tiny things or hold heavy boxes.
1X NEO takes the opposite approach. It’s 5’5″ tall but only weighs 66 pounds—less than half what the others weigh. Instead of heavy motors, it uses thin cables (like tendons in our arms) to move. This makes it super quiet—quieter than a whisper. The hands can even go underwater while washing dishes without getting damaged.
Tesla Optimus is in the middle at 5’8″ tall and 161 pounds. Tesla built it to be simple to make over and over again. Each hand has 22 ways to move, kind of like NEO. Tesla is planning to make 5,000 this year and 100,000 next year, so they know how to build these at scale.
The Power Source: The Big Innovation
Here’s the coolest part. IRON uses a new type of battery called a solid-state battery. Normal phone and car batteries use liquid inside them, and that liquid can catch fire if the battery gets damaged. This new battery uses solid materials instead, so it can’t catch fire. Plus, it has way more power packed in.
IRON’s battery is literally double the power of what Optimus has. It’s also 30% lighter and 30% more powerful. This matters a lot because heavier batteries mean heavier robots, which need more power to move around. It’s a big problem that IRON just solved.
1X NEO uses a regular battery that lasts 4 hours. It charges back up pretty fast too—just 6 minutes of charging gives it another hour of work time. Instead of fancy new battery tech, 1X made NEO use less power by being smart about how it moves. It works great right now in homes.
Tesla Optimus uses the same kind of batteries that power Tesla cars. They’re proven and reliable, but not as powerful as IRON’s new solid-state battery. Tesla knows a lot about batteries though, so they can squeeze out good performance from them.
The Robot Brains: How They Think
The thinking part of these robots is wild. IRON has three super-powerful AI chips that can do 2,250 trillion math operations every second. That’s a lot of thinking power happening really fast.
IRON’s AI works in a special way. Most robots see something and then describe it in words before deciding what to do—like you having to say out loud everything you see before moving. IRON skips that middle step. It goes straight from seeing something to doing something about it. This makes it way faster at reacting. The AI learned from 100 million videos of real people doing real things.
1X NEO learns differently. Instead of just learning from videos, NEO actually learns while it does real work in real homes. It can predict if a task will work before it even tries—kind of like being able to picture folding a shirt correctly before you touch it. As it does more tasks in more homes, it gets smarter and better.
Tesla Optimus uses AI that Tesla made for self-driving cars. Since Tesla already figured out how to make cars drive themselves, they know a lot about how to teach robots to understand the world. Optimus gets better every time Tesla improves their self-driving software.
Moving Around: Making It Look Natural
Getting robots to walk like humans has been super hard, but all three are doing really well now. IRON walks at about 6.5 feet per second and can keep its balance even on hard concrete. It learned how to walk by watching thousands of hours of real people walking, not by following programmed rules. Videos went viral because people couldn’t tell if it was a real person walking—that’s how good it looks.
NEO walks at 4.6 feet per second normally, but can sprint up to 20 feet per second when it needs to. That makes it the fastest one. It moves smoothly through homes and around furniture without that clunky robot look. The tendon cables help it move naturally.
Optimus walks at about 4.3 feet per second right now, but Tesla is working to get it to 16 feet per second. It moves really smoothly because of how the motors are put together. It’s refined and clean-looking.
What Are They Doing Right Now?
This isn’t just science fiction anymore—these robots have real jobs. IRON is being put in stores where it greets customers and shows off new products. A big Chinese steel company is already using IRON to check on their machines and spot problems before things break. Xpeng plans to use these inside their own factories by the end of 2026, then expand from there.
NEO is made just for homes and people can already order one right now. It does laundry, answers the door, brings you things from other rooms, and puts dishes away. Cool part? It learns your home and what you like. The longer it works with you, the better it gets at helping.
Optimus is working right now inside Tesla’s factories on assembly lines. This proves the robot actually works in real, tough environments. Tesla is keeping them inside the factory to perfect them before selling them to others.
Staying Safe Around Humans
NEO is super safe for homes. It’s light (so bumping into it won’t hurt much), made of soft materials with no sharp parts sticking out, and whisper-quiet. The hands are waterproof, so it won’t break if it gets wet while cleaning. Perfect for homes with kids and pets.
IRON is built to absorb impacts with its flexible skin and muscles. The solid-state battery can’t catch fire. It even has a face that changes expression so people can tell what it’s thinking before it moves.
Both think about safety but in different ways—NEO for safe home use, IRON for safe commercial spaces where people are watching.
How Much Will They Cost?
NEO costs $20,000 to buy right now or $499 per month to rent. You get free delivery in 2026, help when you need it, and a three-year promise that it will work. You can pick blue, beige, or black.
IRON’s price hasn’t been announced yet. But we can guess based on what Xpeng charges for other robots—probably between $20,000 and $30,000 when it comes out in late 2026. Business customers might pay differently than regular people.
Optimus also doesn’t have a price yet. Elon Musk has mentioned maybe $20,000 to $25,000 once they make a lot of them. Right now Tesla is only using them in their own factories.
When Can You Get One?
The robot business is growing crazy fast in 2025. Tesla wants to make 5,000 this year and 100,000 next year. China’s BYD company is making 1,500 this year and planning 20,000 next year.
Xpeng plans to make a lot of IRON robots by late 2026. They’ll use them in their own factories first, then sell them.
1X has the head start. You can order NEO right now and get it in 2026. Being first to put robots in real homes means 1X will learn faster than their competition.
Sup up on Xpeng IRON vs Tesla Optimus vs 1X NEO
The truth is there’s no one winner. It depends on what you need. If you run a store or factory, IRON has the newest tech, better battery, and can handle lots of different jobs. Its quick thinking helps it react faster in busy places.
For your home, NEO is the only choice right now. You can order it today, it’s made to be safe, it’s quiet, and it learns the jobs you need done. $20,000 is a lot, but it’s the most you can actually buy in 2026.
Optimus plays the long game. Once Tesla makes 100,000 of them, they could be the cheapest. The self-driving AI that already works on cars gives it a solid base. But you’ll have to wait a while to buy one.
The robot world is moving crazy fast. By 2050, there could be 1 billion robots helping people, doing 62 million jobs that people do today. We’re at the turning point right now where robots stop being science fiction and start being tools that help us work.
