A LeRobot-native, stationary bimanual leader-follower kit from Fashionstar (sold via Seeed Studio). Two Violin leader arms teleoperate two follower arms (Viola, 300g payload / 470mm reach, or Cello, 750g payload / 670mm reach), all 6-DoF + parallel gripper with brushless servos. Ships pre-assembled with explicit LeRobot bimanual configs, plus ROS 2 and MoveIt2 support, targeting imitation-learning and pick-and-place data collection.

The StarAI Star Arm is a Chinese LeRobot-native dual-arm teleoperation kit designed for low-cost imitation-learning data collection. It uses a leader-follower architecture: human-manipulated Violin leader arms drive matching follower arms, with 'Hover Lock' technology to hold pose. Followers come in two variants — Viola (470mm reach, 300g payload) and Cello (670mm reach, 750g payload) — both 6-DoF plus a parallel gripper (66mm max opening) driven by brushless servos with 2mm repeatability. A full bimanual station is 4 arms total (2 leaders + 2 followers). The kit advertises 'ready to go, no assembly required' options and ships with explicit LeRobot bimanual configurations for dual-arm imitation and pick-and-place, alongside ROS 2 and MoveIt2 integration.
Derived from its documented connections — mechanical, electrical, software.
