3D Printed Collaborative Robot - Open Source Software, Manuals & 3D print files ·
Designed for Embodied/Physical AI, Safety & Ease of use
[2025-04-10] Test
[2025-04-03] Beta Release! Contributions from the open-source community are highly encouraged, and we welcome feedback and bug reports through the GitHub Issues page.
PAR6 is a 3D-printed collaborative robot arm platform designed for research, education, and rapid prototyping in physical AI.
The project combines mechanical design files, assembly documentation, and software resources to support full-stack robotics development.
Key focus areas:
- Embodied AI and physical AI experiments and validation
- Teleoperation workflows and human-in-the-loop control
- Learning from demonstration (LfD) pipelines
- Imitation learning and dataset generation
- VLA-style data collection for AI-native robotics
- Accessible robotics research through open hardware and open documentation
