ROI Calculation Logic

Replacing conventional multi-joint robots (with expensive integrated gears/motors) with this technology could reduce component count and maintenance costs due to wire drive. For example, if a conventional joint mechanism's annual maintenance cost is ~$33K/unit (AI est.) and power consumption is ~$7K/unit (AI est.), this technology could reduce these by an average of 15%. For a factory operating 10 robots, this could result in an annual saving of (~$33K + ~$7K) × 10 units × 15% = ~$60K (AI est.). Including space reduction from miniaturization, the total economic impact could reach ~$200K annually (AI est.).
