EngineAI SA01

Product Overview

A highly expandable bipedal robot platform built on open-source foundations, supporting user customization and offering outstanding cost performance Open-source full-body design Full-chain technology sharing empowers global developers to collaboratively innovate and iterate. SA01 features a fully open-source robot design, with completely open hardware structures and interfaces. Users can customize and modify the mechanical structure according to their needs, including adding modules such as robotic arms to expand the robot’s functional applications. The open architecture enables research teams to deeply understand the robot’s body structure and freely experiment with various hardware modifications, supporting secondary development and innovative experimentation across different scenarios. Open-source motion control algorithms Transparent low-level code accelerates algorithm development and iteration. SA01’s motion control algorithms and software framework are fully open source. Users can access the underlying control code, modify or replace algorithm modules as needed, and directly deploy self-developed control strategies onto the physical robot for validation. The open-source strategy lowers the barrier for algorithm experimentation, allowing users to understand the control principles of bipedal robots through source code analysis and quickly develop their own motion algorithms. Self-developed straight-leg gait Abandoning the traditional bent-knee mechanical walking style of robots, the self-developed straight-leg technology enables the robot to walk with natural human-like strides. SA01 is equipped with a high-performance drive system and advanced motion control algorithms, delivering exceptional dynamic performance. The coordinated six degrees of freedom in both legs enable smooth self-developed straight-leg gait, while powerful real-time balance control ensures stable walking even during acceleration, sudden stops, or external disturbances. Full-stack self-developed high-performance joints Self-developed joints achieve deep integration between hardware and software, with sensors capturing motion data in real time and algorithms responding rapidly for adjustment. SA01 is equipped with fully self-developed integrated joint modules. The hip and knee joints deliver peak torque up to 160 Nm, providing strong power output for demanding high-load tasks. The innovative joint design incorporates dual absolute magnetic encoders, ensuring precise joint position recovery even after power loss and restart. Each joint also features comprehensive built-in safety protection mechanisms. Bipedal coordinated control Coordinates six degrees of freedom across both legs to achieve smooth, self-developed straight-leg gait. Real-time balance control The open architecture helps students and researchers gain a deeper understanding of robot control principles. Aluminum alloy body Balances impact resistance with lightweight design, providing strong protection for internal hardware. Aircraft-grade aluminum alloy materials The body frame and shell of SA01 are made from aircraft-grade aluminum alloy, ensuring durability while effectively reducing overall weight. High-strength shell The precision-designed aluminum alloy exoskeleton enhances overall stability. The high-strength shell provides comprehensive protection for key internal components, ensuring stable performance under harsh environments and intensive use. Ultra-high joint flexibility Equipped with 12 degrees of freedom, enabling flexible adaptation to various complex scenarios. Large-capacity battery SA01 is equipped with a 15Ah / 54.6V high-energy-density lithium battery pack featuring quick-swap support to meet long-duration continuous operation requirements. Operating temperature range: -20°C to 55°C
