ER-SCARA 400

The 'ER-SCARA 400' designation maps most directly to the ESTUN ER3-400-SR, a 4-axis industrial SCARA robot with 400 mm reach, 3 kg payload, and ±0.01–0.02 mm repeatability, manufactured by ESTUN (China). The extracted facts also contain substantial material about EFORT's ESR3-4-400 (a competing Chinese SCARA with similar specs priced at €8,312), Topstar Technology's TR002-HP400 series, and several academic research papers that use SCARA-type robots as experimental platforms — none of which are the same product. The ESTUN ER3-400-SR is a conventional industrial robot arm that executes programmed tasks autonomously once deployed; a human programs and sets it up but does not perform the task itself during operation. Several specification conflicts exist across third-party reseller sources (repeatability, weight, IP rating, controller brand), reflecting the typical variance of secondary market listings rather than authoritative discrepancies.
