What is the Robotera Star1?
The Robotera Star1 is a general-purpose humanoid robot developed by Robotera in Beijing, China. It is designed for high-speed bipedal locomotion and modular manipulation research. The robot features 55 degrees of freedom distributed across its body, a top speed of 13 km/h, a 20 kg payload capacity, and a battery life of up to 4 hours. A standout feature is its modular end-effector system, which allows tool changes in under 30 seconds. As a pre-commercial prototype, the Star1 is primarily targeted at research institutions and logistics labs exploring humanoid mobility and human-robot interaction.

Price & Value
New MSRP: ~$120,000
Used range: N/A
Priced around $120,000, the Star1 is positioned as a premium research platform comparable to other high-DOF humanoids. It undercuts the Fourier GR-1 while offering significantly more degrees of freedom, but it is not yet a commercial product. Compared to the Unitree H1 ($90,000, ~19 DOF), the Star1 provides three times the articulation at a 33% higher cost, making it better suited for dexterous manipulation studies. As a pre-commercial prototype, pricing is not final and may shift once mass production begins.
Who Is It For?
Best for: - University robotics labs needing 55 DOF for advanced locomotion and manipulation research - High-speed bipedal walking studies where 12.9 km/h top speed is critical - Human-robot interaction projects requiring modular tool-switching
Not for: - Heavy industrial material handling (payload limited to 20 kg) - Immediate commercial deployment (still a pre-commercial prototype) - Budget-constrained projects (Unitree H1 offers lower cost at $90,000)
Alternatives & Comparison
The Star1 competes in the high-DOF humanoid research space. Key alternatives include the Unitree H1, Tesla Optimus, and Fourier GR-1.
| Model | Price | Available | Key Difference |
|---|---|---|---|
| Unitree H1 | $90,000 | yes | H1 has ~19 DOF vs Star1’s 55; H1 is slower (11.9 km/h) but cheaper. |
| Tesla Optimus (Gen 2) | Undisclosed | no | Optimus aims for general-purpose tasks at lower eventual cost, but Star1 leads in raw speed and articulation for research. |
| Fourier GR-1 | Undisclosed | preorder | GR-1 offers 44 DOF (11 fewer) and a lower top speed, while Star1 prioritizes maximum mobility and modularity. |
Verdict: For researchers prioritizing extreme mobility and dexterity, the Star1 is the clear winner with 55 DOF and class-leading speed. The Unitree H1 remains the better value for labs focused on basic bipedal locomotion at a lower cost. Tesla Optimus is more of a long-term bet for general-purpose tasks, while the GR-1 strikes a middle ground. If your budget allows ~$120,000 and you need the highest articulation available, the Star1 is the pick.
Use Cases & Capabilities
Bipedal Locomotion Research
With a top speed of 12.9 km/h and 55 DOF, the Star1 is an ideal platform for studying dynamic walking, running, and fall recovery. Researchers can experiment with gait optimization and obstacle negotiation thanks to its high-speed capabilities. The modular end-effectors also allow the robot to manipulate objects during locomotion tests.
High-Speed Walking Studies
The Star1’s 3.6 m/s sustained speed pushes the envelope for humanoid velocity. This makes it suitable for testing control algorithms that require rapid sensing and actuation, such as autonomous navigation in unstructured environments. The robot’s 4-hour battery provides ample runtime for extended outdoor trials.
Human-Robot Interaction
The Star1’s humanoid form factor and modular tool-switching enable natural interaction studies. Its ability to change end-effectors in under 30 seconds supports tasks ranging from object handovers to collaborative assembly. The robot’s size (171 cm, 63 kg) approximates a small adult, making it relatable in social robotics experiments.
History & Background
Robotera, headquartered in Beijing, China, unveiled the Star1 humanoid in 2024 as a research platform for advanced locomotion and manipulation. The company has not disclosed a founding year, but early announcements emphasized the robot’s modular end-effector system and class-leading 55 degrees of freedom. As of 2026, the Star1 remains a pre-commercial prototype with no reported production units. It is the first and only generation of the Star series, targeting research, logistics, and service industries. Robotera continues to solicit use-case inquiries directly from potential partners.
Buying Used — What to Check
Verify payload rating Payload is critical for manipulation tasks; early prototypes may have undocumented limitations.
Check firmware version Pre-commercial robots often have experimental firmware; ensure you can upgrade to stable releases.
Inspect modular connectors The 30-second tool-swap claim depends on robust end-effector connectors; examine for wear or modification.
