Efficiency in a mobile disinfection robot is a balance between speed, energy consumption, path optimization, and sanitization effectiveness. To evaluate performance, we must consider how much area is sanitized, how quickly the process is completed, how much energy is used, and how effectively pathogens are eliminated. By defining key metrics—such as coverage efficiency, energy efficiency, path optimization, and disinfection effectiveness—we can quantify and compare different approaches, ensuring that the robot operates at peak performance while maintaining cost-effectiveness. Below were the metrics that were considered.
1. Coverage time efficiency ( m2 per second )
Coverage efficiency compares the fastest method of covering as much room as possible, but doesnt take into account energy, the logical solution to maximise this metric would just be to use multiple UV-C lamps.
2. Energy efficiency ( m2 per Watt )
This disregards cost. And factors in energy, but doesn’t take into account time.
3. Coverage Cost efficiency ( m2 per second per unit cost )
This would factor in cost, but cost is difficult to quantify. Cost of materials varies. Also investigating the cost is out of scope of this project.
4. Coverage time and power efficiency ( m2 per second and watt )
