The build

Step 01

Build the belt

Make a motor-driven conveyor.

Step 02

Add a sensor

Place a sensor over the belt to read each item.

Step 03

Add a gate

Use a servo arm to push items aside.

Step 04

Sort

Items get flicked into bins by category.

Working Principle

The sensor identifies each passing item and triggers the servo gate at the right moment to divert it into the matching bin.

The science behind it

A closer look

It's automated sorting: detection plus timed actuation — the heart of factory and recycling lines.

Variables to test

  • 1 Sort by colour vs by size — which is more reliable?
  • 2 Speed up the belt — does timing break down?
