Pick and Place of Hard Disk Media |
using Electrostatic Levitation    |
----------------------------------

Description:
------------
This video shows stable electrostatic levitation of a hard disk
media (an aluminium disk) used in a pick and place task.
Firstly, the experimental setup is shown where the electrodes
and disk are highlighted. Then the pick up task is shown in
which the disk is picked up using a linear motor with the
electrodes attached. To show that the disk is really levitated,
it is disturbed from the side, upon which a lateral oscillating
motion can be observed. The place task is realized by releasing
the disk automatically on the same location as where it was
picked up. Finally, a close up of the air gap shows the air gap
between disk and electrodes more clearly if control is switched
on or off. The air gap is about 300 micrometer with an applied
voltage to the electrodes of 1 kV.
