{"id":"dobot-mg400","model_id":"MG400","name":"Dobot MG400","summary":"The Dobot MG400 is a four-axis collaborative robot with a 440 mm working radius and a 500 g payload (750 g maximum). It has a 190 mm x 190 mm base footprint and ±0.05 mm repeatability for desktop-scale automation. Programming options include drag-to-teach, Lua, and a graphical interface.","study_notes":["The MG400 uses servo motors and a high-precision encoder; its drive and controller are integrated in the all-in-one base.","Programming options are drag-to-teach, Lua, and a graphical interface.","The ENC interface supports ABZ encoders.","Communication interface includes TCP/IP and Modbus TCP; port 502 is used for Modbus by default and should not be occupied.","Base size is 190 mm × 190 mm.","Rated voltage is 48 V.","Maximum payload is 750 g; the specification table lists payload as 500 g (max. 750 g).","The base includes a built-in cooling fan.","Installation is desktop.","Vibration suppression algorithm is stated to increase multi-joint motion stability time by 60% and reduce residual vibration by 70%."],"safety_notes":["Collision detection is included for human collaboration.","J2 and J3 motors have brakes.","Operating environment limit is 0 to 40 °C."],"sources":[{"url":"https://www.dobot-robots.com/products/desktop-four-axis/mg400.html","title":"MG400 Collaborative Robot","accessed":"2026-10-26"}],"verification":{"status":"source_checked","checked_at":"2026-10-26","values":28,"method":"llm_source_check"},"updated_at":"2026-10-26","type":"hardware","spec":{"category":"collaborative_robot","manufacturer":"dobot","controllers":[],"axes":4,"payload_kg":0.5,"reach_mm":440,"repeatability_mm":0.05,"weight_kg":8,"supply_voltage":"100~240V AC, 50/60 Hz","power_consumption_kw":0.15,"ip_rating":"IP20","operating_temp_min_c":0,"operating_temp_max_c":40,"joints":[{"name":"J1","range_min_deg":-160,"range_max_deg":160,"max_speed_deg_s":300},{"name":"J2","range_min_deg":-25,"range_max_deg":85,"max_speed_deg_s":300},{"name":"J3","range_min_deg":-25,"range_max_deg":105,"max_speed_deg_s":300},{"name":"J4","range_min_deg":-360,"range_max_deg":360,"max_speed_deg_s":300}],"protocols":["modbus-tcp"],"standards":[],"error_codes":[]},"url":"https://machineschema.com/hardware/dobot-mg400","license":"https://creativecommons.org/licenses/by/4.0/"}
