RoArm-M2-GA
The RoArm-M2-GA is a 3+1 (gripper) DOF smart robotic arm designed for education, research, and lightweight automation. It is driven by bus servos with an ESP32 MCU as the main controller. The arm supports multiple control methods, providing flexible control interfaces and rich communication protocols, making it suitable for desktop-level experimental validation, integration with mobile robot platforms, and teaching scenarios.
With an innovative dual-drive structure, the shoulder joint torque is significantly increased, enhancing both the overall load capacity and structural reliability. Users can perform basic operations without complex setup, while also being able to deeply customize the arm through open interfaces.
