AlohaMini is a dual-arm mobile robot with a motorized vertical lift — beautifully designed, fully 3D-printable, and affordable.

Built for embodied AI research and real-world manipulation. Assemble at home in ~60 minutes, customize every part, and train or deploy with LeRobot.

Note: Use ROS only if you need URDF visualization, RViz inspection, or Gazebo simulation.

Updates#

  • [2026-02-26] Update the fine-tuning and deployment guide for Pi 0.5 on Alohamini ('examples/pi0.5_openpi')

  • [2025-12-18] URDF and simulation assets are now available for visualization and simulation (simulation/src/Aloha/)

  • [2025-11-27] STEP (CAD) files are now available (/hardware/mobile_base/step/)

What Makes It Different#

  • Motorized vertical lift — 0–60 cm travel (floor-to-table reach)

  • 5-camera perception system — top, front, back, and dual arm cameras engineered for embodied-AI reproducibility

  • Completely open-source — hardware and software freely available

  • LeRobot-compatible — works out of the box

  • Clean, modern design — built for both function and aesthetics

  • Low-cost & accessible — engineered so anyone can build a capable robot at home

Quick Start#

Start building and running AlohaMini:

  1. Hardware acquisition — Purchase components and 3D print parts
    See BOM & 3D-Print

  2. Assembly — build the robot in ~60 minutes (SO-ARM pre-assembled)
    See assembly guide

  3. Software setup & teleoperation — install, connect, and control the robot
    See software guide

Same URDF & control stack across both versions — only structural materials differ.
Official store links are optional purchase channels for complete robots / kits.
AlohaMini remains open-source and can be self-built from the BOM, 3D-print files, and assembly docs.
