Overview
Pharma Bot was an autonomous medicine-delivery robot for the e-Yantra Robotics Competition run by IIT Bombay. I led a 12-person team to build a system that perceives, localizes, and navigates a structured environment on its own.
What I built
- OpenCV-based perception with QR code and ArUco marker localization.
- A vision-based localization framework using an overhead camera to estimate the robot’s pose in real time.
- A digital twin in CoppeliaSim, kept synchronized with the physical robot’s state, plus constrained path planning and task scheduling.
Highlights
The team ranked among the Top 16 nationally. More than the result, this was where the discipline of tying simulation to hardware — a digital twin that actually tracks reality — first clicked for me.
