Technical specifications
| Availability | In production |
|---|---|
| Nationality | Japan |
| Degrees of freedom, overall | 14 |
| Degrees of freedom, hands | 1 DoF grippers each hand |
| Height [cm] | N/A |
| Max speed (km/h) | 0 |
| Strength [kg] | 15 |
| Weight [kg] | 30 |
| Runtime pr charge (hours) | N/A |
| Safe with humans | Yes |
| CPU/GPU | N/A |
| Ingress protection | N/A |
| Camera resolution | Built-in in-hand RGB camera on the gripper (resolution unpublished), optional ZED-121210 stereo camera add-on for a top-down workspace view |
| Connectivity | CAN-FD control bus (1 kHz), wired — no built-in Wi-Fi/Bluetooth, networking depends on the host computer |
| Operating system | None onboard; driven from a Linux host (Ubuntu 22.04/24.04) via ROS 2 and SocketCAN |
| LLM integration | Compatible with external vision-language-action (VLA) models via Hugging Face's LeRobot and similar frameworks, run on the user's own compute |
| Latency glass to action | Not a fixed hardware spec — depends on the external AI model and host PC. The CAN-FD control bus itself runs at 1 kHz (1 ms cycle) |
| Motor tech | DAMIAO quasi-direct-drive (QDD) brushless motors (DM-J4310, DM-J8009P), plus one higher-torque non-QDD motor (DM4340) at the base joint |
| Gear tech | Low-ratio planetary gearboxes (9:1 to 40:1 depending on joint), which preserve backdrivability |
| Main structural material | Aluminum and stainless steel, with MISUMI aluminum-frame support pillars |
| Number of fingers | 2-finger gripping claws |
| Main market | physical-AI/embodied-AI teams worldwide — data collection, teleoperation, and VLA model training, Robotics research labs, universities |
| Walking Speed [km/h] | 0 |
| Shipping Size | N/A |
