BREE-Assets

The Open-Source Toolkit for Reproducible Bimanual Manipulation

BREE-Assets provides all the files and protocols you need to construct, calibrate, and standardize your bimanual robotic platform. By following our blueprints, you eliminate physical hardware variance across different sites and ensure your data and policies remain perfectly compatible.

Structural Hardware

A standardized frame built from 4040 aluminum profiles defines the precise geometric layout of the robot arms, cameras, lighting, and workspace.
