Belt conveyors are key components of industrial automation systems. This modular mini conveyor belt is designed to replicate a miniature version of an industrial automation process that can be used in educational environments for industrial automation illustration using microcontrollers. It consists of a speed controller to drive a stepper motor with up to 2 Amps, and an Arduino board for automating tasks. The speed can be varied from 0 to 300 RPM, and is displayed on a 3-digit seven segment display module.
The design was conceived to have the least amount of complex mechanical elements as possible, however, two special non trivial steps are required: cut and joint the timing belt that transfers rotation from the motor to the axle, and make the conveyor belt.
