Desktop 4-Axis Collaborative Robot
DOBOT MG400 Desktop 4-Axis Collaborative Robot

The DOBOT MG400 is an industrial-grade desktop 4-axis collaborative robot arm with a compact base footprint smaller than an A4 sheet of paper. It features flexible deployment, easy operation, and safe collaboration, making it ideal for diverse small-batch automated production needs.
With a maximum payload of 750 g and a working radius of 440 mm, the MG400 fully meets the requirements for light-duty desktop applications. It supports drag teaching, collision detection, and other collaborative functions, allowing fast and efficient deployment on production lines. The MG400 is the perfect choice for automation and intelligent production where compactness, precision, and high cost-effectiveness are key.
Product Features:
- Compact Footprint
To maximize production space and easily integrate into existing environments, the MG400 adopts a compact all-in-one controller and body design. With a footprint of only 190 mm × 190 mm, it can fit into an area smaller than an A4 sheet of paper. - Simple and Efficient Productivity Boost
With a simplified robotic design concept, the MG400 lowers the barriers for small and medium-sized enterprises to adopt automation. - Shorter Deployment Time
The all-in-one, lightweight design allows for flexible deployment and plug-and-play operation. - More Programming Options
Supports drag teaching, graphical programming, and Lua scripting, suitable for applications of varying complexity and developers with different skill levels. - Higher Programming Efficiency
With direct teaching and interactive guidance, users can significantly reduce the difficulty of robot programming and improve development efficiency. - Improved Calibration Efficiency
By combining trajectory compensation algorithms with precise motion control, the MG400 can reduce trajectory calibration time by over 80%, ensuring faster setup and smoother operation.
