ER4-SCARA

The ER4-SCARA designation as used in these facts primarily refers to the Estun ER4-550-SR-U, a 4-axis SCARA industrial robot manufactured by Nanjing Estun Automation (founded 1993, Nanjing, China), with 550 mm reach, 4–12 kg payload (conflicting sources), IP20 protection, and EtherCAT/Modbus TCP connectivity. The extracted facts are highly heterogeneous, drawing from at least four distinct systems/contexts: the Estun ER4-550 SCARA, the Scorbot ER4-PC/ER4u educational arm (Eshed Robotec/Intelitek), research papers on modular SCARA robots (Erle Robotics), and unrelated humanoid/6-axis robot content. As a programmed industrial SCARA, the robot autonomously executes its assigned pick-and-place or assembly tasks without a human performing or driving those tasks, qualifying as Autonomous for its intended industrial task. Several hardware specification conflicts exist between sources regarding payload capacity.
