🎯 Overview

LeRobot Anything is a low-cost, universal, leader-follower teleoperation system for any commercial robot arms through 3 hardware configurations. Designed for researchers, educators, and robotics enthusiasts, it provides a standardized interface for diverse robot platforms. This project focus on extending the Lerobot to control any real robot in both real scene and simulation.

For detail, see our technical report here.

🎯 Target Environment (Docker coming soon)

• OS: Ubuntu 20.04
• ROS: Noetic
• Simulation: SAPIEN integration (Built upon ManiSkill)

❓ FAQ

1. Is this project compatible with my XXX robot arm?

A: Please first refer to the Supported Robots section above, where part of compatible arms are listed along with corresponding config. Note that this project aims to provide a universal teleoperation framework and example control code. Here, “compatibility” means that the operator can intuitively control the corresponding follower arm on hardware side by using UArm.
This is independent of different brands’ software APIs — it only depends on the joint topology of the robot. To find your robot’s joint topology, check Hardware Guide.

---

2. How can I develop based on my own follower arm?

A: Start by reading LeRobot-Anything-U-Arm/src/uarm/scripts/Uarm_teleop/servo_reader.
This script reads all UArm joint angles and is wrapped as a ROS node.
You need to write a subscriber based on your follower arm’s API that receives joint commands from the '/servo_angles' topic and sends them to your arm. Dobot Controller is a simple example.

If you prefer not to use ROS communication, you can directly read the UArm’s servo command data and send them to your follower arm.
See this ARX example for reference.
