The MG400 Robot Arm belongs to the Industrial Robot arm line of the Dobot brand.
MG400 is a lightweight desktop robot smaller than a piece of A4 paper. Designed to be lightweight, user-friendly and safe, the MG400 can be easily integrated into any production line or laboratory bench, making it accessible and affordable. Because of its cost and capabilities, the MG400 thrives in small-scale manufacturing, laboratory automation, and research and development applications.

DOBOT MG400 is manufactured for small and medium-sized businesses that must meet seasonal needs and a high degree of customization. This compact, industrial-grade robot can adapt to short-run productions seamlessly, and customers can use it to automate processes including touchscreen testing, loading and unloading of parts, dispensing, quality inspection, and more.
MG400 performance
Main features:
- Professional hardware: MG400 has a controller design based on a Linux real-time system and uses the most advanced 1-4 servo drive technology.
- High precision: All axes use low voltage DC servo motors with high precision absolute position encoders and low backlash mechanical transmission parts. All of this puts the MG400 in a superior position to produce repeatability up to ±0.05mm.
The MG400 was designed with small-scale production in mind. With a footprint of 190mm (7.48 inches) × 190mm (7.48 inches), the robot is light enough to carry in a backpack and compact enough to place on a table as well as next to a production line, providing you with full flexibility in your business.
Outstanding advantages of MG400
With safety as the core, MG400 applies an advanced collision detection algorithm with a collision force threshold of less than 12N. The robot stops immediately when it touches an obstacle, putting it in the same class as the world's best robots.
The applied vibration suppression algorithm increases the repetition bandwidth stability by 60% and reduces the remaining vibration by 70% without affecting the spatial trajectory accuracy of multi-axis motion. This means the robot tool will move more steadily without shaking, ensuring smooth performance of tasks.
The MG400 leverages the TrueMotion Algorithm, a technology developed by DOBOT that features speed planning and dynamic algorithms. This allows the robot to provide precise trajectories at a steady speed, thus successfully completing tasks such as bartending.
With the dynamic gravity compensation algorithm applied in the robot, first-time users can easily move the robot anywhere they want. The MG400 will be able to move to programmed things with best-in-class accuracy.
Easy connection
Install the robot on your desk, plug it in, and connect it to your PC using an Ethernet cable or to your tablet via Wi-Fi. Finally, open our software and the MG400 is ready to go.
MG400 is compatible with a wide range of other technologies, suitable for high-end and complex applications.
With the support of TCP/IP and MODBUS TCP, the robot can be connected to a variety of technologies such as: smart cameras for dynamic positioning of changing parts on the conveyor.
PLC to collaborate with multiple robots, third-party visualization software like DobotVisionStudio - gives you the flexibility you need to create quick and simple test applications, a variety of plug-and-plays, helping users set up applications faster, and even user-customized robot application programs.
