PROJECT TOPICHealthcare, Assistive & Bio-Mechatronics
Automated Medication Dispensing Swarm
A secure hospital logistics concept exploring encrypted RFID compartment locking, indoor LiDAR floor navigation, and nurse credential badge verification for scheduled pharmaceutical deliveries.
Secure Chain-of-Custody Internal Transit
- ✓Eliminates nursing transit time by delivering scheduled medications directly to ward rooms.
- ✓Maintains chain-of-custody logging with timestamped badge access to locked bins.
- ✓Navigates busy hospital corridors smoothly using dynamic obstacle avoidance.
The Engineering Challenge
Problem / Objective
Nurses spend extensive shift hours walking to central pharmacies to retrieve medications, while open delivery carts risk misplacement.
Conceptual Signal Flow
