Welcome to the Galaxea developer community, and thank you for becoming a user of the LEMO dual-arm desktop operation platform. This manual will help you complete product unboxing, mechanical installation, cable connection, and getting the whole system up and running, and further introduce the LEMO hardware configuration, teleoperation, data collection, model deployment verification, and the use of development interfaces.

1. Product Introduction​

LEMO is a dual-arm development platform for embodied intelligence developers, integrating teleoperation, data collection, model deployment verification, and secondary development, and covering the entire embodied intelligence development workflow from data collection and model training to inference and deployment. The product highly integrates dual A1Z robotic arms, G1Z grippers, a multi-view synchronized vision system, and the LEMO-CCU control box. It supports out-of-the-box use, quick assembly and disassembly, and flexible placement, helping universities, research institutions, and robotics development teams efficiently conduct dual-arm operation research and embodied application development.

2. Safety Instructions​

Before using the LEMO dual-arm desktop operation platform, please carefully read the following safety instructions to ensure the safety of operators and personnel nearby, and to ensure the normal operation and long-term stable use of the device.

2.1 Operational Safety​

  • Qualification requirements: Operators must receive necessary product training and be familiar with LEMO's installation procedures, operation methods, safety regulations, and emergency response measures to ensure they have the ability to operate the device correctly and safely. Personnel who are not yet familiar with this manual should be guided and supervised by experienced personnel when approaching or operating the device.
  • Operating environment: Please provide a workspace that meets the requirements for LEMO, ensuring that the installation platform is flat and stable, with no flammable or explosive materials, liquids, strong magnetic field interference sources, or other potential hazards nearby. The device should be placed in a clean, dry, and well-ventilated environment to avoid device failures or safety accidents caused by environmental issues.
  • Operating standards: Please strictly follow the steps and methods specified in this manual. Do not touch the robotic arms, grippers, camera stand, or other moving parts at will while the device is running, and do not adjust key settings such as joint parameters, speed, acceleration, or safety limits without authorization, to avoid device damage or personal injury.

2.2 Device Safety​

  • Power safety: Use a power adapter that meets the device requirements, ensuring that the power supply voltage is stable within the specified range (24 V), to avoid device damage caused by voltage fluctuations. Also, regularly inspect the power cable and related connection points to ensure they are intact and firmly connected.
  • Structural fixation: Before each use, check whether the operation platform base plate, left and right robotic arms, camera stand, grippers, and related fasteners are securely installed. If you find a loose base, structural shaking, or missing fasteners, stop using the device and complete the inspection and repair.

3. Emergency Stop and Remote Control​

  • The emergency stop button can immediately cut off the device's power supply.
  • The remote control enables remote pause, stopping the LEMO dual-arm motion.
