🧰 One-Stop Parts Procurement
Thanks to comprehensive open-source resources, developers can easily obtain all required components. The entire mechanical structure can be manufactured through 3D printing, with almost no custom machining required. Once printing is complete, using Unitree's highly reliable 8010 motors and standard battery packs, the parts can be assembled in 3-5 hours.
⚙️ Balanced Performance and Scalability
The Qmini integrates 11 Unitree 8010 motors, an actuator that has been validated in various commercial robotics platforms:
- 10 motors drive the robot's main locomotion system
- 1 motor, located in the neck, is reserved for custom extensions
This modular design encourages developers to design and prototype their own extensions—enhancing functionality, aesthetics, or interactivity.
🤖 Developer-Oriented Design
Adhering to the principle that good tools should be easy to use, Qmini is designed with simplicity and cost-effectiveness in mind. The platform supports multiple affordable control boards, with the default reference configuration being the Raspberry Pi 4 Model B. Developers can also freely choose alternative controllers based on specific requirements or projects.
🌍 Diverse Applications
The Qmini is suitable for a wide range of use cases:
- Individual Enthusiasts – 3D print, assemble, and program your own robot at home
- STEM Education – Suitable for robotics competitions, laboratory experiments, and graduation projects
- Research Institutions – A compact platform for testing dynamic gait, motion control, and AI algorithms
- Interactive Entertainment – Ready to perform in animation, stage performances, or other creative tech experiences
