The SA01 is EngineAI's open-source, education-and-research-focused bipedal humanoid robot. Within EngineAI's lineup it is the entry-level platform — described by the company and observers as a "robot pit platform" for getting started in humanoid robotics, aimed at universities, laboratories, and individual developers studying gait, reinforcement learning, and embodied intelligence.
Price & Availability
The SA01 is positioned as EngineAI's most affordable, accessible humanoid — the education tier of the SA01 / PM01 / SE01 / T800 range. EngineAI emphasizes a "relatively controllable" price for the SA01 and open algorithm/control code. Exact current pricing should be confirmed directly with EngineAI; the SA01 debuted alongside the PM01 and SE01 at CES 2025.

Specifications
EngineAI publishes the SA01 primarily as an open research/education platform rather than with a detailed consumer spec sheet. Known characteristics: it is a bipedal humanoid built around EngineAI's self-developed joints and end-to-end neural-network approach, with open training and control code (ROS-compatible, simulation support) and extensible hardware I/O for third-party sensors and hands. It is intended for teaching curricula and research on locomotion, perception, human-robot interaction, and whole-body control. Buyers should request exact dimensions, DOF, and battery figures directly from EngineAI.
Model Breakdown
The SA01 is the education and research entry point of EngineAI's humanoid family. The progression runs SA01 (education/research) → PM01 (lightweight high-dynamic open platform) → SE01 (full-size flagship) → T800 (heavy-duty industrial).
Buyer's Guide: What to Know
The SA01 is a learning platform first. It is designed for universities, labs, and individual developers entering humanoid robotics — algorithm and control research, not deployment.
Open source is the core value. Open algorithm/control code and simulation support make the SA01 a teaching and experimentation tool.
It is the affordable entry tier. If your goal is to start research without a flagship budget, the SA01 is EngineAI's intended on-ramp — but confirm exact specs and price directly, since EngineAI documents it lightly.
SA01 vs Similar Robots
- SA01 vs EngineAI PM01 / SE01: Same family — the SA01 is the entry-level education platform; the PM01 and SE01 are progressively more capable.
- SA01 vs AgiBot Lingxi X1: Both are open-source education/research humanoids aimed at universities and developers.
- SA01 vs Unitree G1: Both serve as research platforms; the G1 is a more established, fuller-featured product.
