## Common questions

### What is Asimov 1?

Open-source DIY humanoid robot kit designed for builders, engineers, and researchers working with physical AI on real hardware. Standing 1.2m tall and weighing 35kg, Asimov 1 features 25+2 degrees of freedom (27 total DOF), 5-finger hands, aluminum alloy construction, and modular actuators. Ships as a complete kit for $20,000 (or $23,000 self-sourced) with full BOM, CAD files, MuJoCo simulation model, and a pre-trained walking policy on GitHub. Requires 100+ hours of build time. Onboard compute (likely NVIDIA Jetson-class), ROS2-based control, Wi-Fi connectivity. The platform includes a Digital Asimov browser-based simulation for testing before building. Part of a multi-generational roadmap: Asimov 0 (legs only, Jan 2026), Asimov 1 (full body, Apr 2026), Asimov 2 (bimanual deployment-ready, coming soon), with a target of state-of-the-art humanoid by Asimov 5.

### How much does Asimov 1 cost?

Asimov 1's price is not publicly disclosed. DEPLOY has no verified price on record for Asimov 1 from Menlo Research. Physical-AI systems like this are often sold through enterprise contracts or operated as a service rather than at a public list price; check the manufacturer for the latest.

### Is Asimov 1 actually deployed in the real world?

Asimov 1 is at the prototype stage: it exists, but DEPLOY has no verified real-world deployment on record. Manufacturer capability claims should be read as claims pending independent verification.

### Who makes Asimov 1?

Asimov 1 is made by Menlo Research, based in Singapore, founded in 2023.

### Can you buy Asimov 1?

Asimov 1 is at prototype stage and is not yet available for sale.

### What are alternatives to Asimov 1?

On the DEPLOY registry, comparable humanoid robots to Asimov 1 include Walker S2, Digit, Unitree G1, Atlas.

### How does Asimov 1 compare to Walker S2?

Asimov 1 and Walker S2 (UBTech Robotics · 18 deployments) are both humanoid robots on the DEPLOY registry. Asimov 1 has 0 verified deployments on record. Compare both records for specs, safety, deployments, and verified-vs-claimed autonomy.

### Is Asimov 1 a top humanoid?

On DEPLOY's intelligence score, which blends verified deployments, safety, adoption, media, and IP signals, Asimov 1 ranks in roughly the top 88% of humanoid models tracked by the registry.

### What is Asimov 1's maturity stage?

Asimov 1 is at the prototype stage on the DEPLOY maturity ladder (research, prototype, pilot, commercial, production). Prototype stage means demonstrations exist but commercial readiness is not yet established.

### Where is Asimov 1 deployed?

No verified deployments of Asimov 1 are currently on the DEPLOY registry. DEPLOY records deployments only when verified at a named site with a primary source; absence may reflect pre-deployment, research, or manufacturer-internal use.
