Product Description

The Dobot MG400 is an ultra-compact, 4-axis desktop robotic arm with a footprint smaller than a sheet of A4 paper. Built for small-batch, flexible production, it delivers repeatable automation on a benchtop — with drag-to-teach programming and built-in collision detection that make it fast to deploy and safe to work alongside.

Key Features

  • Ultra-compact footprint — a 190 × 190 mm base fits on any workbench, smaller than a piece of A4 paper.
  • Drag-to-teach programming — hand-guide the arm to set positions, no coding required to get started.
  • Collision detection — built-in safety response for working near people.
  • Fast and precise — ±0.05 mm repeatability with joint speeds up to 300°/s for cost-effective smart automation.
