Performance You Can Rely On
Built for Endurance
Built with industrial-grade harmonic drives and servo motors designed for precision and continuous operation, along with 17-bit absolute encoders for accurate position feedback. A reinforced structure and upgraded drive system support consistent high-precision performance, ensuring product quality.
Seamless Vision Integration
An integrated Gigabit Ethernet cable provides high-speed, stable connectivity for Ethernet-based peripherals such as cameras and sensors. Internal cable routing protects connections and improves long-term durability.
Compact and Lightweight
Weighs only 20 kg with a compact Ø190 mm footprint. The robot arm features a carbon fiber body, enabling easy relocation and integration into tight, space-limited environments.
Where it really stands out is the compact controller lineup. The space-saving AC control box (269 × 178 × 86 mm, 3.8 kg) keeps standard installations tidy—whether mounted under a table or inside a cabinet. For mobile platforms and battery-powered deployments, the 2.5 kg DC control option (209 × 176 × 82 mm) supports a simpler, lighter integration.
Easy Programming and Control
UFACTORY Studio is accessible through any modern web browser on Mac or Windows, or as a downloadable desktop application. A drag-and-drop graphical interface, hand-guiding teaching, and guided tutorials support fast deployment of automation tasks without requiring prior development experience.
Try Software 
Developer-Friendly Interface
Supports open-source Python and C++ SDKs, with ROS and ROS 2 packages included. Pre-built programs, API documentation, and support for third-party tools streamline advanced application development.

Simulation Ready
Compatible with leading simulation platforms including Gazebo, RoboDK, MuJoCo, and NVIDIA Isaac Sim. Test motions, validate projects, and train AI policies in virtual environments before deploying to the real robot.
Safe by Design
Built-in collision detection monitors for unexpected contact and triggers an automatic protective stop to support safe human–robot collaboration.
Self-Collision Detection prevents unintended contact between robot joints, protecting the arm from mechanical stress and hardware damage.
Configurable Safety Controls
Configure safety boundaries and motion limits (TCP speed, joint speed, and joint range) in UFACTORY Studio for controlled, predictable operation.
Connect external safety devices via I/O and set the robot’s response in software (Stop, Reduced, or Safeguard Stop) to support safer workflows and simpler cell integration.
Add a UFACTORY 6-axis force torque sensor for precise force detection in close-contact applications such as rehabilitation, massage, and research.
Integrate with the Tools You Need
UFACTORY products are built for open integration, connecting seamlessly with both official accessories and trusted third-party solutions. Standard mechanical interfaces, wrist I/O, developer SDKs, and support for standard industrial protocols speed up integration and customization, helping you adapt as needs evolve.
