Noetix N2 Athlete

Introduction / Overview

The Noetix N2 Athlete is the humanoid robot that earns its name in public. It was the first humanoid capable of performing continuous backflips — indoors and outdoors — before going on to finish second in the world's first humanoid half-marathon in Beijing, completing the full 21 kilometers in 3 hours and 37 minutes, and starring in Noetix's two-gold, one-silver medal haul at the World Humanoid Games, where the company entered nine events from the 100 meters to floor exercise and solo dance. No compact humanoid on the market carries a comparable public performance record — and the market responded with more than 2,500 orders, a surge that tripled Noetix Robotics' valuation.

Developed by Beijing-based Noetix Robotics — the Tsinghua-rooted startup founded in September 2023 behind the consumer Bumi and the Hobbs W1 bionic service robot — the N2 embodies the company's philosophy of competition-grade dynamics at disruptive cost. Standing approximately 118 cm and weighing around 30 kg, with 18 degrees of freedom, 150 N·m of maximum knee torque, and running speeds up to 3.5 m/s, the N2 packs frontier locomotion into a platform sized and priced for universities, research labs, exhibition operators, and serious developers rather than only corporate R&D budgets.

For buyers, the N2's proposition is simple: the dynamic capabilities that flagship humanoids demonstrate on carefully staged videos, this robot has proven in open competition — on roads, on tracks, and on gymnasium floors, timed and judged in public.

Design and Features

Competition-Grade Dynamic Locomotion

The N2's movement repertoire defines its class:

• Continuous backflips — the first humanoid to chain backflips repeatedly, in both indoor and outdoor environments, demonstrating explosive power and landing recovery no compact competitor matched.
• Sustained running to 3.5 m/s — sprint-class speed for its size, with the endurance pedigree of a completed 21 km half-marathon at race pace.
• Full athletic vocabulary — large strides, single- and double-leg jumps, somersaults, complex terrain adaptation, and choreographed dance routines, the repertoire showcased across nine World Humanoid Games events.
• Marathon-proven durability — 3 hours 37 minutes of continuous competitive operation is public evidence of thermal, mechanical, and control robustness that datasheets cannot convey.

Self-Developed Motion Control

The N2 runs Noetix's in-house motion-control algorithms on Noetix-designed control boards and motor drivers — the vertically integrated stack that lets hardware and software co-optimize for dynamic performance. High-torque actuation (150 N·m peak at the knee) paired with a lightweight ~30 kg bionic structure produces the power-to-weight ratio behind the backflips.

Onboard Perception and Edge Computing

Dual depth cameras provide real-time 3D perception, processed by onboard edge computing for decision-making without cloud dependency — the N2 adapts to complex terrain and dynamic environments autonomously, a requirement for the outdoor competition settings it was proven in.

Practical Utility

Athleticism doesn't preclude work: the N2 carries approximately 5 kg continuously while walking, and its 118 × 47 × 29 cm compact format transports easily between venues, labs, and classrooms — a robot one person can move and one budget line can justify.

Developer Access

Open interfaces support research and secondary development, from locomotion experiments to choreography programming — with software extensions available including multilingual interaction add-ons — making the N2 a working research instrument rather than a sealed performer.
