ESP32 4-DOF Robot Arm Kit RoArm-M2-S with High-Torque Serial Bus Servos

Discover the RoArm-M2-S, an innovative 4DOF (Degrees of Freedom) smart robot arm that heralds a new era in robotics. This robotic arm is distinguished by its lightweight design, weighing less than 850g and offering an effective payload. With a 360° omnidirectional base and three flexible joints, its working area extends to a diameter of up to one meter, allowing great flexibility and reach. The Joint-Direct-Drive design not only enhances repositioning precision, but also increases structural reliability. Thanks to the innovative dual-drive technology, the torque of the shoulder joint is doubled. The robot arm is powered by a powerful ESP32 MCU main control module that supports multiple wireless control modes and offers a variety of interfaces and communication protocols. The user-friendly, cross-platform web interface greatly simplifies entry. The robot arm is compatible with ROS2 and various host computers, supporting numerous wireless and wired communication modes.
