Epson's first collaborative robot arrives in Japan with Python support and a 900 mm reach
Seiko Epson Corporation has launched its first collaborative robot, the AX6-A901S, in the Japanese market. The six-axis cobot features a 900 mm reach, a 6 kg payload, and a repeatability of ±0.03 mm. Constructed with a lightweight carbon-fibre arm weighing approximately 18 kg, it includes a compact RC-A101 controller supporting AC and DC power for potential integration with autonomous mobile robots (AMRs) and automated guided vehicles (AGVs). Programming is facilitated by Epson's AX Portal software, which supports both visual block-based interfaces and Python code. The robot offers ISO Class 5 cleanroom compatibility and IP54 protection based on design evaluations, targeting applications in pharmaceutical, medical-device manufacturing, and laboratory automation. Orders opened on October 29, 2026, following an initial debut in June 2025.
