Intro
The design philosophy guiding the XPENG next-gen IRON is "extreme anthropomorphism", a purposeful departure from the purely utilitarian, mechanical aesthetics adopted by many competitors. The rationale behind this choice is to foster greater trust and natural interaction in customer-facing and co-working environments. The robot’s platform is designed to support customization for different body shapes and sexes, enhancing its ability to integrate into various service roles.
Physically, the Next-Gen IRON is a full-size humanoid robot, standing approximately 1730 cm tall and weighing 70 kg in its latest R&D iteration. This structure includes a humanoid spine, bionic muscles (likely 3D lattice polymer), and a fully covered with knitted skin. This highly articulate design boasts 82 DoF across the body and 22 DoF in the hands, granting it sophisticated movement capabilities and industry-leading manual dexterity. Crucially, the robot pioneers the application of an all-solid-state battery architecture in robotics, offering ultimate lightweight characteristics, ultra-high energy density, and enhanced safety.

The robot is the first in the industry to commercialize an all-solid-state battery architecture. This is a fundamental technology transfer from XPENG’s EV development expertise. The use of solid-state technology provides key advantages: ultimate lightweight characteristics, ultra-high energy density, and enhanced safety compared to traditional lithium-ion batteries. Mitigating weight while maintaining high power output is crucial for humanoid robotics, where dynamic stability and payload capacity are heavily influenced by the mass distribution, particularly in the lower body and the battery pack itself.
