Epson Boosts Safe Human-Robot Workflows with New SCARA Line

A world-leading developer of SCARA robots, Epson Robots, announced the expansion of its SCARA range with the release of its latest safety-enhanced, control-optimized GX-C Series robots. The series features the newest version of its software development platform, Epson RC+® 8.0, servo drivers with GYROPLUS vibration reduction system, and the RC800A robot controller with SafeSense technology. Epson has devised its new GX-C Series SCARA robot range to enhance operational safety, minimize setup and maintenance costs, improve workflow efficiencies, and maintain a high standard of robotic control.

Before the inclusion of advanced safety-oriented software, work cells within which SCARA robots and other automated industrial machinery were required to work would need physical safety barriers such as cages and/or light curtains to ensure a safe distance between the robots and human workers. While these measures were and are effective, the downsides are that facility and/or operations managers must plan for extra costs concerning protective physical barriers and account for the loss of space that could otherwise incorporate more workcells, but are impossible to squeeze in due to the space that physical barriers can take up.

The ideal solution resides in economising on space, saving on installation costs, while enhancing worker safety, and reducing process downtime. The demand for such a solution has given rise to efficient controllers with integrated safety features, such as the RC800A Controller with SafeSense Technology.

De-Risking and Optimizing Workflows

The inclusion of adaptive safety measures means that customers can utilize the open architecture, high-acceleration capacity, high-performance motion control, and positioning of the RC800A Controller while enhancing worker safety and economizing on work cell space constraints. The RC800A controller also integrates smart servo drives with the GYROPLUS vibration reduction system to minimize residual vibrations, which conserves energy, optimizes performance, and reduces wear on robotic parts, which in turn, saves on maintenance costs.

The SafeSense technology includes both SLS (Safety Limited Speed ) and SLP (Safety Limited Position) safety functions so that SCARA robots can adapt to workspace changes related to the activities of human workers. Robots are fed information regarding their surrounding environment, using additional safety-assisting tools such as a sensor mat and a light curtain (which send safety input signals) to slow their speed and change position to avoid unnecessary contact with human workers and enhance safety, all the while maintaining workflow efficiencies.

Thorough workspace risk assessments can be used to assist the implementation of SLS and SLP safety measures, identifying potential hazards to notify and train automated robotic equipment to respond quickly and dynamically to minimize workspace injuries, complying with safety standards (such as ISO 10218 and ISO/TS 15066 for collaborative robotics), reducing inefficiencies, and maintaining throughput.

GX-C Series Robots

The GX-C series architecture reduces settling delays, provides stable acceleration, and fast cycle times. With the Epson RC+ software's intuitive interface, integrated debugger, and 3D simulation capabilities, control engineers can operate effectively. The sturdy, small construction guarantees consistent performance at the maximum velocity and recommended load. Important features that save installation and upkeep costs include integrated Ethernet, battery-free encoders, and incorporated software.

Customers can create their required system setup by adding conveyor tracking, force control, machine vision, component feeders, fieldbus, and third-party tools. Optional arm reach and adaptable mounting contribute to a space-saving work cell layout. Models are supported by Epson staff and are available for cleanroom use, ESD-safe environments, and IP65-rated conditions.

Attendees of Automate 2025 (May 12-15, 2025) can personally observe the capabilities of Epson’s new GX-C series bots at booth #2818.
