Key Takeaways
1. XPeng’s Iron robot impressed audiences with lifelike walking, prompting a demonstration to prove it wasn’t an actor.
2. A new video showcases Iron’s dance routine, highlighting its precise movements and flexibility as explained by CEO He Xiaopeng.
3. Iron learned to dance by watching human dancers and picked it up in just two hours using a large AI model, a significant improvement over previous methods.
4. The robot’s advanced design features, including a flexible spine and balanced waist, enable it to mimic human biomechanics and maintain smooth walking.
5. XPeng plans to use Iron in various settings, competing with other companies like Tesla and Samsung in the humanoid robot market.
We shared last week that XPeng’s Iron robot captured attention with its almost lifelike walking during a presentation. The company’s leader even had to invite engineers to open up the humanoid’s leg to prove to the audience that it wasn’t just an actor playing a role. XPeng has since put out a new video showcasing the robot’s inner workings, exposing a structure made of actuators, servos, and wiring.
Dance Moves on Display
The latest video, narrated by CEO He Xiaopeng, kicks off with Iron performing a dance routine. According to Xiaopeng, dancing is a great way to show off the robot’s precise movements and flexibility.
Learning from Humans
If you’re amazed by Iron’s dance skills, it’s because it learned in a traditional way: by watching human dancers. The engineers provided it with motion data through a large in-house AI model.
Xiaopeng mentioned that Iron picked up the dance in just two hours, which is a huge drop from the two weeks it took when the engineers applied reinforcement learning or trial-and-error methods.
Advanced Design Features
Iron’s ability to replicate human walking is due to its spine and waist design. The engineering of the spine gives flexibility to the torso, while the waist is crafted to maintain balance for the rest of the body, even as it sways, mimicking human biomechanics. The precision control and mechanical strength is what apparently allows Iron to keep its smooth walking style, even with some outer layers taken off.
XPeng aims to see Iron utilized in various real-world settings, from factory environments to retail spaces. The robot is set to be another avenue for the company’s AI-driven mobility initiatives. However, XPeng isn’t the only one working on humanoid robots. Elon Musk’s Tesla introduced an Optimus robot in 2021 and has been providing regular updates, while Samsung has hinted at its own version after Toyota showcased a four-legged walking chair.
