WHAT’S HAPPENING
Position the suction cup over a
sheet of thin plastic. Turn the
power on with the switch. The
motor turns the mechanical
linkage that forms the arm of the model. The arm drops
downward and the suction cup engages the sheet of plastic.
The arm then rises up again, bringing the sheet of plastic
with it. You can swivel the arm to move the sheet of plastic
into place. You can release the suction pressure to drop the
plastic into place by pressing the suction release valve
button. Robotic arms like this are used in factories to place
windshields onto cars during production.
Done!
