About OPTi3
Purpose-built for robotic welding, the OPTi3 combines Neuromeka's collaborative robot technology with advanced welding capabilities to deliver consistent, high-quality welds across a wide range of applications. Its lightweight design—weighing about 11 kg—makes installation, relocation, and manual handling simple while maintaining industrial performance.
The robot's symmetrical structure minimizes unnecessary movement during left- and right-side welding, improving efficiency and reducing cycle times. Equipped with a welding-specific end effector, sensorless collision detection, impedance control, direct teaching, and arc sensing (through-arc seam tracking) for 2F fillet welds, the OPTi3 provides a flexible and easy-to-use platform for modern welding automation.

Compact Radius of Rotation
OPTi3's symmetrical arm structure — the same design that minimizes unnecessary movement between left- and right-side welds — lets the folded arm rotate within a 200 mm-diameter envelope. That small swing radius means the robot can pivot between weld positions without extra clearance, making it easier to fit into tight-cell layouts.
