PROJECT TOPICHealthcare, Assistive & Bio-Mechatronics
UV-C Decontamination Autonomous Vehicle
An automated disinfection robotics concept examining optical UV-C ray coverage calculation, room surface shadow mitigation, and redundant PIR motion sensors to deactivate lamps instantly when humans enter.

Autonomous Surface Decontamination Safety
- ✓Calculates cumulative UV-C radiative dosage based on distance and exposure time.
- ✓Features redundant passive infrared (PIR) sensors to shut down lamps if humans enter.
- ✓Navigates autonomous paths around hospital beds, chairs, and medical carts.
The Engineering Challenge
Problem / Objective
Manual chemical room wipe-downs miss hidden shadowed crevices and expose cleaning personnel to harsh chemical fumes.
