LEGO Sorting Robot
A computer-vision LEGO sorting robot built on a Hiwonder MasterPi platform.
Computer vision in motion
Built around a Raspberry Pi 4B and mecanum-wheel base, the robot uses LAB color detection to locate orange baskets and red or blue bricks.
Custom Python control handles staged approach logic, PID steering, servo control, and camera-arm tracking across many live hardware iterations.
Built for the real world
The system uses burst-and-cooldown alignment to stay stable while navigating the physical environment.
Every module was prototyped, tested, and refined on the actual robot—not only in simulation.
Computer Vision
Autonomous Systems
Human-Centered Tools
Hardware-led iteration
Mechanical constraints, lighting conditions, and object behavior all shaped the final control system.
The robot became more reliable through repeated live tests and practical adjustments.
From prototype to proof
The final build brings sensing, movement, and sorting together in one tangible system.
It’s a working example of turning an ambitious idea into a useful machine.
