Key Significance
Noetix Bumi is a product that achieved a high-performance bipedal humanoid robot at under $1,400 [1][4]. As a case that proves humanoid robots can be made available to the public at a price cheaper than flagship smartphones, it is evaluated as a milestone symbolizing the democratization of Physical AI.
- Price Innovation: Significantly cheaper than existing high-performance humanoid robots (Unitree H2 ~$16,000) [8]
- Vertical Integration Strategy: Cost reduction through self-developed controllers and actuators [2]
- Educational Accessibility: Greatly lowered the barrier to entry for robot research for students, researchers, and hobbyist developers [1]
- Mass Production Potential: Easy to scale up utilizing supply chains within China [2]
Manufacturer: Noetix Robotics
Company Overview
| Item | Information |
|---|---|
| Official Name | Songyan Dynamics Beijing Technology Co., Ltd. (Songyan Dynamics) |

| Total Rounds | 5 | 24 investors including Hangzhou Dongfang Jiafu, Jiadao Valley Investment, United Pioneers Capital |
| Valuation | ~$200M | Approximately 3x increase after N2 half-marathon success in April 2025 (per reports) [2][7] |
Technical Specifications
Physical Specs
| Item | Spec | Source |
|---|---|---|
| Height | 94cm (~3.1 feet) | [1][4] |
| Weight | 12kg (26.5 lbs) | [1][4] |
| Degrees of Freedom (DOF) | 21 DOF | [8] |
| Battery | 48V, 3.5Ah+ | [1] |
| Runtime | 1-2 hours (depending on usage pattern) | [1] |
| Price | ¥9,998 (~$1,370) | [1][3] |
DOF Configuration
21 DOF supports complex movements including bipedal walking, upper body manipulation, and head movements [8]. Although the specific joint distribution is not disclosed, based on typical humanoid configurations, it is estimated to be distributed as follows:
- Lower Body: Knee flexion, hip rotation, ankle joints - bipedal walking and balance
- Upper Body: Elbow flexion, shoulder joints - upper body movement
- Torso/Head: Torso rotation, head motion - dynamic movements and interaction
The above distribution is an estimate; exact specs require manufacturer confirmation
Note: Lower than Unitree H2 (31 DOF) but higher than basic educational robots, reflecting a consumer-oriented design philosophy [8].
Control System
- Self-developed Domain Controller: Internal design without relying on third-party suppliers [2]
- Motion Control Algorithm: Hybrid approach of Imitation Learning + Reinforcement Learning (per reports) [1][8]
- Sensors: Camera-based vision, voice recognition [1]
Motor Capabilities
According to official announcements and reports [1][4]:
- Stable bipedal walking
- Jumping (single leg, both feet)
- Dance movements
- Dynamic balance maintenance
- Object recognition and interaction
Cost Optimization Strategy
Key strategies by which Noetix achieved the $1,400 price (per TechNode reports) [2]:
1. Vertical Integration
Instead of purchasing standard control boards and actuators from third parties, Noetix designs these core modules internally. This enables:
- Elimination of supplier premiums
- Close hardware-software optimization
- Motor controller customization specialized for Bumi’s motion profile
2. Lightweight Composite Materials
- Base: Composite materials
- Reinforcement: Selective metal use only where needed
- Result: 12kg weight reduction enables smaller motors and batteries -> additional cost savings
3. Utilizing Domestic Supply Chains
- Parts procurement to assembly all conducted within China
- Minimized tariffs, logistics, communication costs
- Maximized scale advantages in mass production
4. Self-developed Low-cost Actuators
- Developed actuators optimized for consumer grade instead of expensive industrial actuators
- Set durability-cost balance point
Target Markets
1. Education Market
- Graphical Programming: Drag-and-drop programming support for children [1]
- Open Programming Interface: Low-level control access for university robotics programs and researchers [8]
- Affordable Practice Platform: Students can test algorithms on actual humanoids
2. Consumer/Home Use
- Voice Interaction: For companion and educational scenarios [1]
- Compact Size: 94cm suitable for home environments [3]
- Entertainment: Dance, movement demonstrations
3. Research/Developers
- Motion control algorithm testing
- Machine learning model development
- Human-robot interaction paradigm research
Market Response
Sales Performance (November 2025, per reports)
- Over 100 units sold within 1 hour of JD.com launch [1]
- First 500 units sold out in 2 days (during Double-11, Double-12 shopping festivals) [1]
- Pre-order period: November 11 - December 12, 2025 [8]
Related Product: N2 Humanoid
Information about Noetix’s larger humanoid robot N2 [7]:
| Item | Spec |
|---|---|
| Height | 1.2m |
| Weight | 29-30kg |
| Price | ¥39,900 (~$5,500) |
| Max Speed | 3.5m/s (10km/h) |

April 2025 Beijing Half Marathon
At the world’s first humanoid half marathon (21.1km), N2 achieved 2nd place (3 hours 37 minutes) [5][6]:
- 1st: Tien Kung (Beijing Humanoid Robot Innovation Centre) - 2 hours 40 minutes
- 2nd: Noetix N2 - 3 hours 37 minutes
- 3rd: DroidUp X02 - 4 hours 50 minutes
As a result of this achievement, Noetix reportedly received over 1,000 orders within a month, and the company valuation increased [5].
Limitations and Considerations
- Durability Tests Not Disclosed: Detailed durability test results or IP rating not announced [8]
- API Documentation: Complete open API documentation absent (openness emphasized but detailed specs limited) [8]
- Battery Replacement Needed: Battery swap required for long-duration operation (confirmed during N2 marathon) [5]
- Consumer Support System: Service infrastructure verification needed as it’s early stage of mass market entry
Competitor Comparison
| Product | Manufacturer | Height | Price (USD) | DOF | Features |
|---|---|---|---|---|---|
| Bumi | Noetix | 94cm | ~$1,370 | 21 | Lowest-cost consumer, education market target |
| N2 | Noetix | 1.2m | ~$5,500 | N/A | High-performance, marathon 2nd place |
