Modular End-Effector Ecosystem

Transform your robot in seconds with our standardized quick-connect interface (disc-style rotary switch). Swap between:

Electric grippers (for object manipulation)
Vacuum suction cups (for flat/irregular items)
Laser engraving heads (for precision marking)
3D printing nozzles (for additive manufacturing)
Custom tools (via open interface)
Maximize ROI by adapting to diverse tasks without investing in multiple machines.

Open-Source & User-Friendly

Compatible with ROS, ROS2, Python, C++, and Arduino — plus intuitive graphical programming tools like Dobot Blockly, myBlockly, and Luban. Drag-and-drop coding makes it accessible to students and beginners, while advanced APIs empower developers to create custom applications. Perfect for both education and professional use.

Safety First: Collaborative Design

Engineered with full-enclosure construction and finger-safe components to minimize pinch points and foreign object intrusion risks. The robot stops immediately upon contact, ensuring safe human-robot collaboration in shared workspaces — no safety barriers required.
