ROVA 6 Leader Follower Set

LeRobot-Compatible 6-Axis Desktop Robot Arm (SO-101+ Style)

This arm is a compact, table-top robot built for learning and building real robotics AI. It follows the same LeRobot-style workflow as the SO-101: teleoperate, record demonstrations, train a model, and run tasks autonomously. It also adds one extra degree of freedom for improved reach and dexterity.

What you can do with it

• Teleoperate and record demonstrations using leader arm by hand
  

• Create your own dataset for desk-scale manipulation tasks
  

• Train imitation-learning policies and deploy them back to the arm
  

• Run repeatable tasks like pick-and-place, sorting, stacking, and simple assembly-style motions
  

• Handle more angles and approaches thanks to the added joint, which helps with tighter placements and awkward orientations
  

Why the extra DOF matters

Adding a 6th axis gives the arm more flexibility to:

• Approach objects from more angles without repositioning the base
  

• Reduce elbow lock situations, where the arm runs out of comfortable configurations
  

• Produce smoother, more natural trajectories during teleop and replay
  

• Improve success rates on tasks that need a specific wrist orientation while reaching
  

Key features

• 6-DOF arm (6 joints + 1 gripper) with a desk-friendly footprint
  

• Smart serial bus servos with encoder feedback for consistent joint control
  

• USB connection to your computer through a controller/driver board
  

• Designed to fit the same data-to-train-to-deploy loop used in the LeRobot ecosystem
  

Technical snapshot

• Follower arm drive: smart serial servos with encoder feedback (SO-101-class hardware)
  

• Leader arm drive: tuned gear ratios for comfortable hand-guided teleoperation
  

• Software workflow: Python and PyTorch training loop with LeRobot-style datasets and policies
  

System requirements

• A computer that can run Python tooling for data collection and training (commonly set up with Python 3.10 environments)
  

• USB port for the controller and servo bus
  

Who this is for

• Robotics enthusiasts, students, and developers who want hands-on embodied AI at desk scale
  

• Builders who want more dexterity than SO-101 without moving to a much larger or more expensive platform
  

• Teams prototyping the full loop from teleop to dataset to training to deployment
