Commercially Available Industrial-Grade Performance

Professional Hardware: MG400 has a controller design based on Linux real-time system, and makes use of the most advanced 1-to-4 servo drive technology.

High Precision: All axes use low-voltage DC servo motors with high-precision absolute position encoders and mechanical transmission parts with low backlash. All these put MG400 in a superior position to produce repeatability up to ±0.05mm.

Vibration Suppression Algorithm: Fulfill Tasks Smoothly & Steadily

The adopted vibration suppression algorithm increases repeatability bandwidth stability by 60% and reduces residual vibration by 70% without affecting the space trajectory accuracy of multi-axis motion. This means that the robot’s tool will move more steadily without jittering, ensuring smooth execution of tasks.

TrueMotion Algorithm for Applications Requiring High-Accuracy Trajectory

MG400 leverages TrueMotion Algorithm, a DOBOT-developed technology featuring speed planning and dynamic algorithm. This allows the robot to deliver accurate trajectories at stable speeds, thus excelling in tasks like dispensing.

Teaching MG400 is as Easy as Moving Your Own Hand

With the dynamic gravity compensation algorithm adopted in the robot, first-time users can effortlessly move the robot wherever they like. MG400 will be able to move to these taught with best-in-class precision.

Multiple Controls for Beginners & Professionals

MG400 is programmable through teaching and playback, block program, and LUA scripting, suitable for beginners with no programming experience and veteran programmers alike.
