Key Takeaways
- Epson AX6 is the company’s first 6‑axis collaborative robot (cobot), combining the precision of Epson’s industrial line with force‑limiting safety features.
- Payload 6 kg and reach 800 mm make it ideal for light‑to‑medium assembly, inspection, and pick‑place tasks.
- Built‑in Safety‑Rated Output (SRO) 2.5 A and a force‑limit of 5 N allow operation without traditional cages after a risk assessment.
- Compared with Epson’s classic industrial C‑series and rivals such as the Universal Robots UR10e, the AX6 delivers comparable speed and repeatability while adding collaborative‑ready compliance.
- Quick‑change tooling and a 0.02 mm repeatability rating shorten setup time and improve cycle consistency.
Introduction: Epson Enters the Collaborative Space
Epson Robots, long known for high‑speed, high‑precision industrial manipulators, has broadened its portfolio with the AX6 collaborative robot. The new model retains the six‑axis kinematics that underpin Epson’s C‑series but incorporates power‑ and force‑limiting technology that meets ISO/TS 15066 standards. After a formal risk assessment, the AX6 can share workspaces with human operators without the need for conventional safety fencing.
Core Specifications of the AX6
| Specification | Value |
|---|---|
| Payload | 6 kg (13.2 lb) |
| Maximum Reach | 800 mm (31.5 in) |
| Repeatability | ±0.02 mm (±0.0008 in) |
| Maximum Joint Speed | 200 °/s |
| Safety‑Rated Output (SRO) | 2.5 A (ISO 10218‑1 compliant) |
| Force‑Limiting Threshold | 5 N (≈0.5 kgf) |
| Operating Temperature | 0 °C – 45 °C |
| Weight | 35 kg (77 lb) |
| Controller | Epson RC+ with built‑in safety PLC |
| Communication | Ethernet/IP, PROFINET, Modbus TCP, USB‑C |
The AX6’s compact footprint (35 kg) and low inertia enable rapid acceleration and deceleration, which is essential for safe human‑robot interaction. Its controller integrates a safety PLC that can execute emergency stop, speed‑limit, and hand‑guiding commands in under 5 ms.
How the AX6 Differs From Epson’s Traditional Six‑Axis Robots
| Feature | AX6 (Cobot) | Epson C‑Series (Industrial) | Universal Robots UR10e (Cobot) |
|---|---|---|---|
| Safety Rating | SRO 2.5 A, force‑limited | No intrinsic force limiting | ISO/TS 15066 compliant, 10 N limit |
| Payload | 6 kg | 7 kg – 30 kg (model dependent) | 10 kg |
| Reach | 800 mm | 900 mm – 1,200 mm | 1300 mm |
| Repeatability | ±0.02 mm | ±0.04 mm – ±0.06 mm | ±0.03 mm |
| Joint Speed | 200 °/s | 150 °/s – 180 °/s | 180 °/s |
| Tooling Change | Quick‑change flange, <30 s | Manual, >2 min | Quick‑change, ~45 s |
| Programming | Graphical RC+ Studio, ROS‑2 bridge | RC+ Studio, PLC integration | Polyscope, ROS‑Industrial |
The table highlights that while the AX6’s payload and reach are modest compared with larger industrial models, it surpasses many cobots in repeatability and joint speed—critical for high‑precision assembly lines.
Typical Applications
- Electronic Component Assembly – Precise placement of PCBs, connectors, and small sub‑assemblies where ±0.02 mm accuracy reduces re‑work.
- Quality Inspection – Integrated vision systems can be mounted on the flange; the robot’s repeatability ensures consistent inspection points.
- Light Material Handling – Transfer of delicate parts (e.g., glass, lenses) within a shared human workspace.
- Medical Device Manufacturing – Force‑limited operation meets stringent safety requirements for sterile environments.
Integration and Ecosystem
Epson bundles the AX6 with the RC+ Studio development environment, which includes a drag‑and‑drop workflow for non‑programmers and a full‑code API for advanced users. A ROS‑2 bridge released in Q3 2026 enables seamless integration with existing robotics middleware, allowing the AX6 to act as a node in larger autonomous systems.
The robot also supports edge‑computing via an optional Intel NUC module, providing on‑board AI inference for vision‑guided pick‑place without external PCs.
Bottom Line
Epson’s AX6 marks a strategic shift from pure industrial automation toward collaborative flexibility. By embedding ISO‑compliant force limiting and a high‑speed controller, Epson delivers a six‑axis cobot that matches the precision of its industrial siblings while safely sharing
