This is a so called closed loop control for my project. It is all in the 'Control Box'.
Input to the box is the sequence control of Programmable Logic Controller (PLC) and the output is the motor driver. Also the input for the box is feedback for the motor position.
This is how the inside looks like. We have three motors to control. We have a input set value and the main brain is the three tiny black things.
This is the project. The motor at the top is to control the up down movement. Motor at the middle is to control in out movement. Motor at the base is to control left right movement.
It is basically a storage system with a pickup and drop off point. Three of the motors will run to store the 'cars' with instructions from the PLC.
