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.
Key Points
- 1Demonstrates software-only autonomy: overhead camera tracks ArUco marker for position and orientation
- 2Reduces hardware complexity and cost by eliminating onboard sensors, enabling budget-friendly robotics education
- 3Allows practitioners to implement vision-based localization, WiFi motor control, and path planning in labs
Scoring Rationale
Practical, actionable demo with clear hardware/software split, strong educational value, but limited novelty and only single-source documentation.
