Canonical robot record
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.
RoboZaps maintains this record as part of its canonical robotics database. Specs are source-verified where linked; the record compares public facts across manufacturers rather than representing a single robot maker.

Record changelog
- Communication: Ethernet, Modbus, WiFi changed to Ethernet (TCP/IP), Modbus TCP · Jul 9, 2026
tranche-6 verification (corrected): Official 'Communication Interface: TCP/IP, Modbus TCP'. WiFi is not listed for the MG400 (it IS listed for the CR series — likely sibling bleed).
- Max Speed: 3 m/s changed to 300 °/s max joint speed (no linear TCP speed published) · Jul 9, 2026
tranche-6 verification (corrected): AUDIT FIX: MG400 publishes only an angular joint speed; numeric nulled so no false m/s magnitude lands in the m/s-canonical column. '3 m/s' was CR5 bleed.
- Payload Capacity: 0.75 kg changed to 0.75 kg (max; 0.5 kg rated) · Jul 9, 2026
tranche-6 verification (corrected): Official spec: 'Payload: 500 g (Max. 750 g)'. 0.75 kg is the max, not the rated payload — qualifier restored.
