3+1 DOF High-Torque Serial Bus Servo Robotic Arm,
supports flexible expansion and secondary development

Completely open source for the control codes and communication interface documents of RoArm-M2-GA series, supports multiple languages and devices for secondary development. Provides modularized demos and tutorials for zero-based users, easy to get started.

The joint angle feedback can be obtained directly via a 12-bit high-precision magnetic encoder without any reduction groups, which is more accurate, and the actual position of the current target point can be calculated based on the joint angle feedback.

We have developed a dual-drive control algorithm that allows the two servos at the shoulder joint to coordinate their output torque effectively, significantly enhancing the power and the overall load capacity of RoArm-M2-GA Series

Adopts a gear transmission and parallel linkage structure to achieve stable power output and precise parallel opening/closing, effectively reducing gripping deflection. Supports programmatic adjustment of gripper opening and closing angles, enabling flexible adaptation to different object sizes and gripping requirements.

The spacers on the gripper jaws are height-adjustable and removable, enabling stable gripping of objects in different sizes and shapes

RoArm-M2-GA can save JSON instructions for robot control as task files. The task files can be saved in the Flash of ESP32, which will not be lost in case of power loss. The robotic arm can perform complex and repetitive operations by calling these task files.

ESP-NOW is a low-delay ad hoc wireless communication protocol, without the need of Network infrastructures. You can use one robotic arm to wirelessly control other robotic arms, and the control methods can be set as broadcast control, group control, and one-to-one control.

* Note: The broadcast control has no limitation for the number of controlled devices, while the group control allows up to 20 devices. Please refer to the WIKI for more details.

In the Leading-following control mode, the Leader robotic arm will send its joint angle information to other robotic arms via ESP-NOW communication. The other robotic arms which are in ESP-NOW Follower mode will imitate the same actions as the Leader in real time.

RoArm-M2-GA series can be controlled not only by the WEB application, but also supports using other controllers to send JSON commands via HTTP protocol network request, serial communication, or USB communication for controlling and obtaining feedback.

The RoArm-M2-GA robotic arm series provides reserved space on the gripper for camera mounting, allowing easy camera expansion and enabling vision applications
