MEVIUS2

MEVIUS2 is the practical, perception-equipped successor to MEVIUS from the JSK Lab (University of Tokyo), comparable in size to Boston Dynamics' Spot. It is a 12-DoF quadruped (three RobStride03 motors per leg over dual USB-CAN) built from 16 unique metal parts: 11 machined A7075 aluminum links and 5 A5052 sheet-metal components, with the base, hip, and lidar-cover assemblies joined by sheet-metal welding. Perception is multimodal: two Livox MID-360 LiDARs and a Tier IV C1 HDR RGB camera, with FAST-LIO odometry and GPU elevation mapping. The repository ships multiple URDF variants (DAE, STL, Livox), MuJoCo models, a trained RL policy, and the full ROS perception/control stack; mechanical CAD is on Google Drive. Published in IEEE Robotics and Automation Practice 2026 (arXiv:2603.22031).

What you get

• A standardized, machine-readable robot schema derived from the source repo.
• A primary assembly 3D asset is available from models/mevius2_stl.urdf.
• Source-backed bill-of-materials evidence is linked with per-part provenance where available. Prices marked estimated are not yet verified against a vendor.
• A transparent reproducibility score so buildability is a sortable, first-class property.
• Cross-links to the source repo, datasets, models, and forks.
