Heavy-duty industrial robot designed for automotive welding and material handling. 170kg payload. Hollow wrist for cable routing. TP5 teaching pendant with graphical programming.
The Comau NJ4 earns a RoboScore of 79.8/100, placing it in the solid tier for manufacturing and production robots. At $65,000 it sits in the enterprise segment, making it a reasonable choice for teams where cycle time and repeatability is the priority. Key specs include a 170kg payload capacity, 2700mm reach, 6-axis articulation, and an IPIP65 protection rating. Comau delivers a competent platform at this price point. Safety certification and operator training are non-negotiable for floor deployment.
Large-scale operations with integration teams, fleet management capabilities, and multi-year deployment plans. If cycle time and repeatability is your primary decision criterion, the Comau NJ4 deserves a place on your shortlist.
Small operations without dedicated integration resources or where payback period exceeds 3 years. If your requirements center on a different set of capabilities, compare alternatives in the manufacturing category before committing.
