Power Supply Notice

Due to regional differences, the power adapter is not included. If local customs restrict power supplies, please purchase a compatible adapter locally or order one from our store.

Overview

6+1 DOF – More Ways to Move

An additional joint unlocks flexible configurations so your robot can reach hard‑to‑access areas, avoid obstacles with ease, and maintain smooth, consistent motion. The expanded inverse kinematics solution space significantly boosts the success rate of motion planning and control, improving efficiency in real‑world applications.

Brushless Servos

Equipped with 50kg and 100kg brushless servos for higher torque, higher precision, and greater reliability.

No Calibration, Ready to Learn

Preconfigured at the factory—no calibration and no servo parameter tuning required. Just unbox, plug in, and start manipulating right away.

One-Button Hover Hold

The Leader Arm (Violin) handle includes a dedicated button. Press it to hold the arm at any position instantly. Great for quick pauses, fine adjustments, and capturing key moments during demonstrations.

Parallel Gripper (Replaceable Fingertips)

Parallel gripper with a 65 mm opening and a linear rail design for smooth, precise motion. Open-source, 3D-printable fingertips allow for easy customization of the grip for various objects.

All-Metal Frame & Integrated Base

Full-metal construction with bearings at key joints for higher load capacity and rigid, repeatable positioning. The integrated base and aluminum-alloy bracket keep the arm firmly supported under load.

ROS 2

Cello-Violin provides a complete ROS 2 Humble software stack to get you started fast. It includes full meshes + URDF (with accurate inertial models), a driver node for real-time topic-based control and joint-state publishing, and ready-to-use configurations for motion planning and simulation. On top of the core bring-up, we offer practical tools and demos that make development smoother—such as teleoperation, GUI control, and drag-teach workflows—so you can move from setup to real tasks with minimal friction.

MoveIt Motion Planning

Plan safe, collision-aware trajectories and execute complex manipulation moves with ease.

Intuitive Control GUI

A streamlined interface for fast setup, real-time monitoring, and efficient everyday operation.

Drag-to-Teach Demonstration

Teach motions by hand and record precise, repeatable trajectories reliably in just seconds.

Gazebo Simulation Ready

Test, iterate, and validate complete workflows in realistic, physics-based simulation environments.

Lerobot

  • Fully compatible with Hugging Face LeRobot, aligned with the latest PyTorch tooling
  • All integration code is open-source
  • Complete unbox → teleop → record → dataset → train workflow documentation
  • Supports LeRobotDataset (v3) and optional Hugging Face Hub dataset versioning/sharing
  • Start training with just one personal computer, no extra infrastructure required

Isaac Sim

  • Includes ready-to-use USD assets for the StarAI Arm in Isaac Sim
  • Fully compatible with the Isaac Sim simulation environment
  • Enables ROS 2 bridging between the real robot and Isaac Sim for synchronized control and state feedback
  • Supports teleoperation workflows between physical hardware and the Isaac Sim robot model
