DOBOT CR3A Cobot, 6-axis, 620mm Reach, 3kg Payload

Overview of DOBOT CR3A Cobot:

The DOBOT CR3A Cobot is a 6-axis collaborative robot engineered for precision automation, ideal for assembly, inspection, and pick-and-place in industrial, research, and educational environments requiring human-robot collaboration. Key specifications include a 3 kg payload, 620 mm reach, 6 degrees of freedom, and up to 0.02 mm repeatability.

What Is a Collaborative Robot?

A collaborative robot, also known as a cobot, is designed to interact directly with humans in a shared workspace, enhancing safety and productivity compared to traditional industrial robots. The DOBOT CR3A cobot incorporates safety features and user-friendly programming, making it suitable for environments requiring close human-robot cooperation.

Key Features and Specifications:

• Payload: 3 kg
• Reach: 620 mm
• Repeatability: 0.02 mm
• Weight: 16.5 kg

The DOBOT CR3A supports a wide range of automation tasks in tight spaces thanks to its compact footprint and robust IP54-rated construction.

Advantages Compared to Alternatives:

• More accurate than most other cobots at the 3 kg payload class, with up to 0.02 mm repeatability.
• Lightweight design enables easier integration compared to heavier 6 dof robotic arms.
• Graphical programming and drag-to-teach features reduce setup time versus conventional robotic systems or manual labor.
• SafeSkin system (optional) offers electromagnetic pre-collision detection for added human safety.

Common Applications:

• Automation: Pick and place, laboratory automation, quality inspection, and light assembly tasks.
• Industries: Manufacturing, research, and education.
• Recommended for: Facilities with limited floorspace or workflows requiring direct interaction with workers.

Compatibility and Accessories:

DOBOT CR3A is part of the CRA series and can be enhanced with the Safeskin system for 360° obstacle detection and increased safety during collaborative tasks. For end-of-arm tooling and integration options, see our Accessories section.
