Dobot Mg400
Ultra-compact desktop four-axis collaborative robot
Contact for pricing
The Dobot MG400 is a lightweight desktop four-axis robotic arm designed for small-batch flexible production and human-robot collaboration. Its all-in-one design integrates the controller and servo drive into the base, giving it a footprint smaller than a sheet of A4 paper. It supports drag-to-teach programming and built-in collision detection so it can operate safely without a protective fence.

Overview
The Dobot MG400 is an ultra-compact desktop four-axis robotic arm aimed at small-batch, flexible manufacturing and light human-robot collaboration. Its all-in-one design places the controller and servo drive inside the base, letting the whole unit sit within a footprint smaller than a sheet of A4 paper, so it fits readily on existing benches and production lines.
The robot is built for fast deployment and easy use, supporting drag-to-teach programming so operators can guide it through tasks by hand rather than coding every motion. Built-in collision detection lets it stop on contact and work without a surrounding safety fence in suitable settings.
Dobot positions the MG400 for repetitive bench tasks such as loading and unloading, dispensing, inspection, and testing, where its small size and high repeatability suit precise, space-constrained automation.
