About DOBOT MG400

About DOBOT MG400

DOBOT MG400 is a lightweight space-saving desktop robotic arm suitable for diversified manufacturing needs. It is flexible to deploy and easy to use, perfect for small space applications. MG400 is a good fit for automated workbench scenarios in tight workspaces that require fast deployment and changeover.

The Powerful Feature Set of MG400

Space Saving, Light, and Small

With the footprint dimension of 190mm × 190mm, MG400 can fit in any production environment smaller than one piece of A4 paper and free up more space in the plant for production. It is the perfect fit for repeating lightweight tasks and automated workbench scenarios in tight workspaces. The compact desktop collaborative robot weighs only 8kg but has a payload up to 750g.


Simplicity Means Productivity

Simplicity is integrated into a robot's dimension. The robotic arm's elegant design is a solid foundation for easy robotics development. MG400 emulates human actions using a hand-guided teaching pendant. Our technicians made it easy for you; drag and move it to gain knowledge.

Great Boost to Automation

By replacing the highly repetitive and standardized procedures, MG400 optimizes desktop human-collaborative work and helps businesses cut costs. All these measures boost efficiency and quality.


Rich Programming Choice

MG400 offers a wide selection of programming options, including trajectory reproduction, graphical programming, and Lua script programming. An intuitive programming interface and a guided-interactive design lower the barriers to robot applications.

CR5 + MG400 Pick & Place


1. What kind of motor does MG400 use?

MG400 uses a servo motor and an absolute encoder of high precision. MG400 has a built-in encoder battery to ensure continuous recording of data under power failure (theoretical battery life is 2 years).

2. Does MG400 have a control cabinet?

MG400 is an all-in-one design. The controller and servo drive are all on the base of the robot. The size of the base is 190mm×190mm (less than the size of an A4 paper of 209mm*297mm), which is very suitable for flexible deployment.

3. Are there fans in the base of DOBOT MG400?

There is a fan installed in the base. When the temperature of the chip inside the base exceeds a certain threshold, the fan will turn on automatically to enhance heat dissipation.
