ROI Calculation Logic

In a manufacturing facility using robots, conventional control leads to ~100 hours of annual downtime due to frequent stops and re-planning for obstacle avoidance. Assuming a downtime cost of ~$2,000/hour (AI est.) per robot, this results in an annual loss of ~$200K (AI est.) per robot. Implementing this technology could reduce downtime by ~50% (~50 hours), yielding an annual cost saving of ~$100K (AI est.) per robot. For example, deploying two robots could achieve an annual impact of ~$200K (AI est.).
