RoArm-M3
5 + 1 DOF High-Torque Serial Bus Servo Robotic Arm
Supports flexible expansion and secondary development
RoArm-M3 series is a 5 + 1 DOF smart robotic arm designed for innovative applications. Adopts lightweight structure design with an effective payload of 0.2kg@0.5m, it can be flexibly mounted on various mobile platforms. Adopts a 360° omnidirectional base combined with five flexible joints to create a workspace with 1-meter diameter.
The joint direct-drive design enhances repositioning precision and also improves structural reliability, with innovative dual-drive technology doubling the shoulder joint torque
