Dobot MG400 Robot Arm, 440mm reach, 0.75kg payload

Dobot Robotics

$4,495.00

Four-axis desktop collaborative robot with 440 mm reach and 0.75 kg payload. Delivers ±0.05 mm repeatability in a compact 190 mm x 190 mm footprint. Drag-and-teach programming, collision detection, and support for Modbus, TCP/IP, Ethernet/IP, and ROS. Ideal for pick and place, lab automation, light assembly, and precision handling in space-constrained environments.

Dobot MG400 4-Axis Desktop Robot Arm | 440mm Reach | 0.75kg Payload:

The Dobot MG400 is a compact four-axis articulated robot arm engineered for benchtop automation, desktop research, and light industrial tasks requiring precise small-part handling in limited spaces.

Key Features:

  • Reach: 440 mm
  • Payload: 0.75 kg
  • Repeatability: 0.05 mm
  • Weight: 8 kg

The MG400 series from Dobot fits easily on a desktop, with a 190 mm x 190 mm footprint. The four-axis mechanical design is ideal for planar operations and offers straightforward deployment. Native drag-to-teach programming and graphical interfaces lower setup barriers, whether for teaching, research, or small-batch runs. Integration is simple with protocol support for Modbus, TCP/IP, Ethernet/IP and Robot Operating System (ROS), alongside DobotStudio and DobotLink environments. Collision detection and a robust servo system deliver reliability for lab automation, test stands, and flexible production.

Applications:

  • Pick and place automation
  • Laboratory and benchtop workflows
  • Testing, inspection, and electronics handling
  • Small part assembly and process R&D

The Dobot MG400 frequently serves as a benchtop robot arm for researchers, developers, and production engineers optimizing workspace and task repeatability.

Connectivity:

  • Protocols supported: Modbus, TCP/IP, Ethernet/IP, ROS
  • Software: DobotStudio and DobotLink for workflow integration
  • Easy PLC and industrial network compatibility for seamless automation

Dobot MG400 vs Alternatives:

  • Compared to six-axis robot arms such as the UR3, ABB GoFa, or Staubli TX2-90, the Dobot MG400 offers a lighter, more compact alternative for planar or semi-planar benchtop automation.
  • Users needing additional articulation or payload may consider six-axis models; the MG400 excels where footprint and ease of use guide the choice.

Frequently Asked Questions:

  • What is the Dobot MG400? The Dobot MG400 is a desktop-grade, four-axis articulated robot arm designed for flexible, small-format automation and research applications.
  • What is the reach of the Dobot MG400? The MG400 robot arm has a maximum reach of 440 mm.
  • What can the Dobot MG400 automate? Typical applications include pick and place, testing and inspection, electronics handling, and benchtop process automation where precision is required.

Is the Dobot MG400 a cobot?

The Dobot MG400 is not a traditional cobot with dual safe-certified sensors but offers collaborative features such as drag-to-teach and lightweight operation for flexible deployment in research, education, and light industry.

What is the programming difficulty?

The Dobot MG400 is suitable for both beginners and experienced users, thanks to drag-to-teach operation and visual programming in DobotStudio, with advanced scripting also available for developers through Lua and ROS.

Typical ROI timeline?

Return on investment depends on application, but as a compact, affordable alternative to larger cobots, the MG400 often delivers lower initial costs and quicker deployment for small-batch automation.

People Also Ask:

  • Is Dobot MG400 suitable for pick and place? Yes, the MG400 is engineered for precise pick and place automation on benchtop and lab-scale workflows.
  • Can Dobot MG400 run with ROS or Ethernet/IP? Yes, protocol support includes both ROS and Ethernet/IP for advanced process integration.

The Dobot MG400 is a four-axis articulated arm designed for benchtop pick and place, testing, assembly, and laboratory automation tasks on desktop surfaces. It handles precise small-part handling in spaces where larger robots cannot fit, with a 440 mm reach and 0.75 kg payload capacity.
Yes, the MG400 supports Modbus, TCP/IP, Ethernet/IP, and ROS protocols for integration with PLCs and industrial systems. It also works with DobotStudio and DobotLink software for standalone and networked deployment.
The MG400 achieves plus or minus 0.05 mm repeatability and includes vibration suppression that boosts stability by 60 percent and cuts residual vibration by 70 percent. This precision makes it suitable for electronics handling, inspection, and assembly work.
The MG400 has a 190 mm by 190 mm footprint and weighs 8 kg, making it suitable for lab benches and tight workspaces where space is limited. It operates in temperatures from 0 to 40 degrees Celsius in IP20 environments.
The MG400 uses drag-to-teach programming and graphical interfaces in DobotStudio, which accelerates setup and requires no coding experience. Advanced users can also program using Lua scripting and ROS for flexible deployment.

Compact desktop arm versus larger industrial robots:

The Dobot MG400 is a four-axis benchtop robot built for small parts and tight spaces, where a full-size six-axis industrial arm would be impractical. Choose it when footprint, ease of programming, and low setup cost matter more than heavy payload or complex 3D reach.

  • For pick and place of components under 0.75 kg on lab benches or production cells under 190 mm x 190 mm, the compact 8 kg form factor fits where larger arms cannot.
  • When drag-to-teach and visual programming are requirements, the MG400 accelerates deployment compared to traditional robot code.
  • For testing, inspection, and small-part assembly requiring ±0.05 mm repeatability, the stable servo system and vibration suppression deliver precision without the cost of a larger cobot.
  • In research and R&D environments, native ROS and Ethernet/IP support integrate into existing lab automation without extensive custom configuration.
