Autonomous Robot Uses External Vision Tracking
|
6.9
This project demonstrates a fully autonomous differential-drive robot that uses an overhead camera and OpenCV to track an ArUco marker for real-time position and orientation. The ESP32 receives motor speed commands over WiFi and executes PWM-driven motion via a TB6612 driver; all intelligence runs externally. The build costs about 2000 INR (~$20) and targets controlled environments and robotics education.
