The RM Series ultra-lightweight humanoid robotic arm redefines agility and power in a compact design. Weighing just 7.2 kg yet capable of carrying up to 5 kg (peak 9 kg), it offers exceptional performance with a 1:1.44 load-to-weight ratio. Featuring 6-DOF and 7-DOF models, integrated controllers, and robust safety systems, the RM Series is built for flexible automation, safe human-robot collaboration, and long-lasting industrial reliability.
Product Description
The RM series ultra-lightweight humanoid robotic arm is a 6-DOF and 7-DOF robotic arm independently developed and produced byRealMan. This series comprises five models: the RM65/75-B basic versions and the RM65/75-6F six-axis force versions. The robotic arm, including its integrated controller, weighs a total of 7.2/7.8 KG, with a payload capacity of 5 KG and a working radius ranging from 610 to 638.5 mm. Its ultra-compact size, combined with a multi-platform interface system, renders it highly suitable for a diverse array of complex application scenarios. The robotic arm is equipped with a built-in safety module that stops operation upon contact, enabling safe human-machine collaboration, streamlining drag-and-drop teaching, and enhancing the user-friendliness of human-robot interaction.

Features
 | Highly Integrated and Streamlined Design The robotic arm is engineered with a remarkable balance of weight and strength, weighing only 7.2 kg while supporting a rated load capacity of 5 kg. This results in an impressive load-to-weight ratio of 1:1.44, with a peak load capacity of 9 kg. Such specifications make it ideal for applications requiring both agility and power, offering substantial operational versatility in a compact form. |
Robust Safety and Reliability Featuring a fully integrated control box within the arm`s architecture, this design minimizes weight and maximizes ease of deployment. The streamlined configuration not only reduces installation complexity but also enhances the robot`s overall efficiency, making it a practical choice for environments where space and mobility are at a premium. |  |
 | Robust Safety and Reliability The robotic arm is equipped with customizable safety features that can be tailored to meet specific operational needs, ensuring safe interaction and operation. In the event of an emergency, the arm can halt its motion immediately, providing an added layer of security. It has undergone rigorous testing and certification, demonstrating its ability to operate continuously under a 5 kg load for over 30,000 hours without failure, underscoring its reliability and durability in demanding industrial settings. |
