What is Asimov 1?
The most customizable humanoid robot you can buy.
Asimov 1 by Menlo Research is an open-source humanoid robot DIY kit built for whole-body control and locomotion research.
The 1.2 m, 35 kg humanoid ships with a complete bill of materials and step-by-step assembly guide (about 20 hours to build), or can be ordered pre-assembled. Sim-to-real resources for MuJoCo and IsaacLab let you train policies in simulation and run them on the real robot. Developer-friendly interfaces include a Python Client SDK, high-level API/MCP (including remote operation) and low-level APIs for fine whole-body control via gamepad, VR headset or WASD. It ships with baseline locomanipulation policies, firmware and a full software stack, and raw robot data can be extracted for data collection and training.
The DIY kit costs $20,000 with a $499 deposit to reserve a Batch 4 unit; final price may vary by tariffs and shipping. Every order includes dedicated engineer support, weekly assembly office hours, a private Discord channel and a modular, fast-repair design with global spares.
