The DOBOT MG400 is a lightweight desktop collaborative robotic arm with a manipulator range of up to 440 mm a maximum payload of 750 g. The robot is characterized by high precision and repeatability ensured by low-voltage servo motors with absolute position encoders as well as mechanical transmission parts with low backlash. Compact and lightweight, it can easily adapt to confined spaces, with the footprint smaller than a sheet of A4 paper.

The device has four integral joints that make for flexibility and simplicity at the same time. Engineered to be user-friendly, it offers several programming options for users with different skills and experience.

The DOBOT MG400 does not require any safety fences and is capable of interacting with operators, other robots, and various working environments. The cobot is perfect for lightweight industrial and commercial applications, for example, small-batch production, laboratory automation, R&D.
