Webots + OpenCV: Autonomous Multi-Colour Pick-and-Place Robot (Python Demo)
Suggested YouTube Title
“Webots + OpenCV: Autonomous Multi-Colour Pick-and-Place Robot (Python Demo)”
Video Description (copy-paste ready)
Watch an autonomous mobile robot tackle a four-colour pick-and-place challenge inside Webots—all in real time and written entirely in Python.
What you’ll see
Colour-aware perception
OpenCV HSV masking tracks blue → red → green → yellow objects and their matching goals.
Dynamic overlays show bounding boxes, centrelines and live metrics (area, aspect ratio, phase).
Closed-loop control
Gyro-based heading control (90 °/180 ° turns & rotation tracking).
Adaptive proportional steering keeps each object centred while modulating speed as it gets closer.
Task pipeline
Initial navigation ➜ box acquisition ➜ goal approach ➜ retreat ➜ automatic phase switch.
Separate state machine handles each colour phase; logs print progress in the console.
Clean architecture
Runs on Webots’ Python API (Robot, Camera, Motor, Gyro).
Single class (MultiColorRobotController) encapsulates perception, decision-making and actuation.
