Product Features

  1. 1) Reduces downtime by detecting abnormalities in advance (predictive maintenance)
    • The predictive-maintenance function uses Maisart to detect and provide early warnings of abnormalities in drive-system products2 incorporated in robots, helping to reduce downtime.
    • Highly accurate predictive maintenance is realized simply by inserting the card into the robot controller, without having to add any other device or sensor.
    1. 2 Gearboxes, motor encoders, and batteries to maintain position-information memory
  2. 2) Shortened cycle time with automatic parameter adjustment (enhanced force sensor)
    • Maisart automatically adjusts the parameters of systems that utilize force sensors3.
    • Takt time is reduced by 60%4 compared to a conventional method by controlling pressure exerted on target items, thereby helping to achieve higher-speed operations similar to those performed by skilled human hands.
    1. 3 Gearboxes, motor encoders, and batteries to maintain position-information memory
    2. 4 Compared to reference value for connector-insertion operation based on conditions set by Mitsubishi Electric
  3. 3) Shorter startup time though automatic program generation (enhanced force sensor)
    • Operation start and end points need only be entered to automatically generate a program for the shortest-possible operation time.
    • Shortens system startup time by 60%4 compared to a conventional method.
