{"id":"nachi-robotics-mr20","model_id":"MR20","name":"Nachi Robotics MR20","summary":"The MR20 is a seven-axis articulated robot for machine tending and material handling. It has a 20 kg payload and 1260 mm reach, with repeatability of ±0.06 mm. It supports floor and invert/ceiling mounting.","study_notes":["The MR series uses a seventh axis to provide multiple arm postures for a single working TCP and to avoid singularities.","The document states payload can be up to 30 kg when using a 1000 mm envelope.","Floor and invert/ceiling mounting solutions are available.","The document lists robot models MR20-02 and MR20L-01 under MR20 general specifications.","Drive system is AC servo motor; construction is articulated.","Applications listed are machine tending and material handling.","Max working envelope values are stated in radians; they are converted to degrees in the joints field.","Max speeds of 2.96 rad/s are stated for axes 1-3; speeds for axes 4-7 are not present in the excerpt.","The MR series can be combined with a robot slider to tend multiple machines with one robot."],"safety_notes":[],"sources":[{"url":"https://www.nachirobotics.com/product/mr20/","title":"MR20 | Nachi Robotics Systems, Inc.","accessed":"2026-10-25"}],"verification":{"status":"source_checked","checked_at":"2026-10-25","values":30,"method":"llm_source_check"},"updated_at":"2026-10-25","type":"hardware","spec":{"category":"industrial_robot","manufacturer":"nachi-robotics","controllers":[],"axes":7,"payload_kg":20,"reach_mm":1260,"repeatability_mm":0.06,"weight_kg":230,"joints":[{"name":"Axis 1","range_min_deg":-179.9087476710785,"range_max_deg":179.9087476710785,"max_speed_deg_s":169.59550735872367},{"name":"Axis 2","range_min_deg":-119.74817918234206,"range_max_deg":55.00394833255903,"max_speed_deg_s":169.59550735872367},{"name":"Axis 3","range_min_deg":-163.86592940741545,"range_max_deg":134.64508185574346,"max_speed_deg_s":169.59550735872367},{"name":"Axis 4","range_min_deg":-179.9087476710785,"range_max_deg":179.9087476710785},{"name":"Axis 5","range_min_deg":-134.64508185574346,"range_max_deg":134.64508185574346},{"name":"Axis 6","range_min_deg":-359.817495342157,"range_max_deg":359.817495342157},{"name":"Axis 7","range_min_deg":-179.9087476710785,"range_max_deg":179.9087476710785}],"protocols":[],"standards":[],"error_codes":[]},"url":"https://machineschema.com/hardware/nachi-robotics-mr20","license":"https://creativecommons.org/licenses/by/4.0/"}
