Summary:
The Unitree R1 is a compact, ultra‑lightweight humanoid robot designed for education, research, and early‑stage innovation.
Standing 1.21–1.23 m tall and weighing 25–29 kg, the R1 features 20–26 degrees of freedom, a 2‑DoF head, and a fully customizable exterior.
It integrates a large multimodal AI model for voice and image interaction, supports open control interfaces, and offers agile bipedal locomotion at an accessible price point starting at $4,900.
Deliveries begin Q2 2026.
Editorial:
A Humanoid for Everyone
Unitree’s R1 is one of the first humanoids priced for students, makers, and early‑stage researchers, not just labs or corporations.
Its combination of:
- low cost
- light weight
- open interfaces
- multimodal AI
- modular design makes it a true “developer‑first” humanoid.
A Platform, Not a Product
Unlike industrial humanoids, the R1 is intentionally unfinished — a platform for experimentation.
Its 20–26 DoF configuration, customizable shell, and open SDK make it ideal for:
- robotics courses
- AI model testing
- locomotion research
- manipulation experiments
- HRI prototyping
The Most Affordable Humanoid in the World
With pricing starting at $4,900, the R1 is the lowest‑cost full humanoid ever released, undercutting every competitor by an order of magnitude.
This positions Unitree to dominate the education + research segment globally.
