Omnidirectional Motion with Flexible Joints

Designed with flexible joints and a 360° rotating platform, the RoArm-M2-S offers a 1-meter operating range, enabling unrestricted movement in all directions.

Seamless Cross-Platform Web Control

No app installation required—simply enter the robot’s address to connect via PC, tablet, or smartphone. The open-source Web App supports custom UI modifications and feature expansion for advanced users.

Fully Open-Source for Custom Development

The RoArm-M2 series provides open-source control codes and communication interface documentation, supporting multiple programming languages and hardware platforms. Offers modular training resources, making it beginner-friendly.

Lightweight Yet High-Strength Build

Weighing less than 900g, the robotic arm is built with carbon fiber and 5052 aluminum alloy, ensuring stability and durability while maintaining compatibility with various mobile robot chassis.

High-Precision Joint Feedback (0.088° Accuracy)

Equipped with a 12-bit magnetic encoder, the system directly extracts joint angle feedback for enhanced accuracy, allowing for precise positioning of the robotic arm.

Dual-Drive Technology for Enhanced Torque

A custom dual-drive control algorithm significantly increases shoulder joint torque, enabling higher power output and greater load capacity, ensuring smooth and stable operation.

Direct-Drive Clamp for Precise Force Control

The direct-drive clamp design allows for fine-tuned force adjustments, ensuring delicate objects are securely gripped without excessive pressure.

Curve Velocity Control for Smooth Motion

Utilizes an advanced curve velocity control algorithm to minimize oscillations, delivering a natural and fluid movement experience, especially during start and stop operations.
