Open CoPAEI · Humanoid platform

Open SourceMulti-FormHumanoid.

Engineered for motion.
Designed for the future.

01 – Torso

Single Torso unit for dual form factor

02 – Bimanual

Two arms with two types of easily interchangeable grippers.

Mount it on any table and immediately begin teleoperation and data collection.

03 – Bipedal

Easily swappable leg modules.

Imagine the bipedal robot equipped with either feet or wheels.

  1. 02 · Anatomy · 01

    Core module

    Two 22 000 mAh packs, the compute and the 2-axis head live in one sealed torso. Both configurations bolt to the same core.

    • 10 kg torso · 5.2 kg of battery
    • Raspberry Pi 5 · 8 GB
    • 2-axis head · 2 camera modules

  2. 02

    Bimanual

    Two arms on that core. Shoulder, elbow and wrist stack into a limb precise enough for tools built for human hands.

    • 9 DOF per arm · 9 motors
    • 15 kg payload
    • 800 mm minimum reach

  3. 03

    Bipedal

    The same core on two legs. Five motors in each leg carry the machine across ground that was never prepared for it.

    • 5 DOF per leg · 5 motors
    • 10.5 kg per leg
    • 31 kg in bipedal mode

03 · Capabilities
