I’m trying to implement a control system similar to what you see in this video
motors can be controlled by a PC through the Arduino?
does anyone know how to do and knows a software through which control motors?
It looks like eight pivot points, each pivot point having four concentric shafts, each shaft having an arm on the front and a stepper motor or servo at the back to position it. If you make it small enough for the arms to be moved by ordinary RC servos you can control those directly from the Arduino. For anything else you would need to add a driver circuit.
Are there pivots point having four concentric shafts?
