Pneumatic end-effector R-EVO

Product overview
The R-EVO single-function robotic end effector is a modular solution for light automation focused on drilling, temporary fastening and riveting in aerospace and industrial assembly. The system combines a controller, cable, motor and quick-change head modules with process-aware software to enable precise control, real-time monitoring and full traceability.

Why choose the R-EVO?

• Productivity & quality — precise, repeatable drilling and fastening cycles that reduce rework and operator dependence.
• Flexible & scalable — modular single-function heads adapt to multiple process requirements and cobot platforms.
• Process-aware & integrable — software-driven process control and open communication protocols for data integration.

R-EVO loop elements

• Controller — manages motor functions, head modules, safety and external communications.
• Cable — supplies power and signal transmission between controller and motor.
• Motor — two-speed drive controlling rotation, feed, clamping and direction.
• Head module — quick-change single-function modules for drilling, temporary fastener insertion/removal, squeeze riveting and sensing.

Motor, interfaces & software

• Motor control — two-speed gearbox for high-speed/low-torque and low-speed/high-torque; rotation motor: 48 V | 70 A max; feed motor: 48 V | 5 A max.
• Pneumatic control — pneumatic grippers for head change; valves for head change and lubrication/air management.
• Module interface — quick-release mechanical interface, auto shutoff valves (lubrication & air), alignment pins for TCP repeatability, spring-loaded splined gears for automatic engagement, RFID for head recognition.
• EVO software suite — create and optimize drilling/assembly cycles, configure tool and maintenance strategy, live visualization and process curves (EVO Config).
• Options — vacuum connector, dispensing tube receiver, electric contacts; main motor assembly weight ~2.9 kg (typical).
