✓ Good - Robot is suitable for this application
For a uniform rod/arm (EOAT) rotating about its pivot:
For a point mass (workpiece) at distance d from pivot:
Combined inertia of EOAT and workpiece:
Maintain at least 20% safety margin below robot's maximum inertia rating
Measure EOAT mass and dimensions carefully for accurate calculations
Use the actual center of mass of the workpiece, not the geometric center
Always test with actual loads before deploying to production
Account for acceleration and deceleration forces in fast movements
High utilization increases motor temperature - ensure adequate cooling
