Answer 1

Electronics can't make the motions up or down without the aid of mechanical devices, motors, air or fluids. Electronics is only used to control them.

Motors can control vertical (up/down) or horizontal movement with various aids like belts and pulleys, threads and s***w motions. The motor polarity will be reverse alternately for the back and forth motion. Other solution is by the use of pneumatic cylinders controlled by valves and PLDs.
