Key Features & Benefits
- Extended Working Range: The integrated Direct-drive Linear Motor provides an additional 700 mm of travel (available in various lengths) to the xArm 6’s native 700 mm reach, effectively increasing the overall operational envelope by up to 50%.2 This is essential for applications requiring work across a long production line, large-scale pick-and-place, or machine tending with widely spaced input/output areas.
- High Precision and Repeatability: The xArm 6 maintains its industrial-grade performance with a 3$\mathbf{5}$ kg payload capacity and 4$\mathbf{\pm0.1}$ mm repeatability.5 The Direct-Drive Linear Motor itself boasts extremely high-precision motion with a repeatability of $\mathbf{\pm5}$ $\mathbf{\mu}$m (micrometers), ensuring the combined system delivers accurate, consistent results across the entire extended range.
- Direct-Drive Technology: The linear motor utilizes a direct-drive mechanism, contributing to its superior accuracy, speed (up to 6$\mathbf{1}$ 7$\mathbf{m/s}$), and durability.8 This technology offers excellent response and eliminates backlash associated with traditional screw or belt drives.
- Collaborative and Safe Design: The xArm 6 is built with safety protocols, including a collision detection function, to work harmoniously alongside human operators, making it ideal for modern collaborative manufacturing environments.9 The robot arm is constructed from lightweight carbon fiber and aluminum, reducing the system’s weight for easier deployment.
- Seamless Integration and Control: The linear motor is designed for easy integration with the xArm 6, managed through a unified system solution.11 Programming and operation are simplified using UFACTORY Studio, a fully Graphical User Interface (GUI) platform that supports drag teaching for quick task setup without complex coding.
- Open-Source Flexibility: For advanced development, the system supports open-source platforms and offers an SDK with Python, ROS, and C++ compatibility, providing maximum flexibility for research, customization, and integration into existing automation frameworks.
