Created a PLC system based on an Arduino MAX256 board to control X, Y and Z movement of a large object via linear actuators via a joystick. The X and Y movement speed is proportionally controlled. A forth object is moved via the joystick too.

A HMI (human-machine-interface) was created using a pc runing Ubuntu and Java application. The HMI while simple shows the positions of the linear actuators via the pots that are built into them.
