INTER IIT TECH MEET 14.0 MP1
Designed and built an Autonomous Mobile Robot (AMR) for warehouse inventory management capable of:
- Autonomous navigation inside warehouse aisles
- Vertical scanning of racks up to 1.8 m
- QR-based rack identification
- Real-time inventory data logging
- The system integrates SLAM, ROS2 navigation, differential drive motion, and a belt-driven vertical lift mechanism into a unified workflow.
