9.15 Correcting Stop Button Lid
Closure Problems
The stop button lid needs to be properly closed before
the robot can perform its specified missions. On occa-
sions, even when the cover has been closed properly,
the robot does not start its mission and the message
"Lid not closed, please select option again" is displayed.
In order for the robot to be able to execute its missions
the lid needs to be shut, and to form a closed circuit
between magnets on the lid and relays on the body.
This circuit needs to be open when the lid is open.
When the lid is pressed down, it acts as the stop
button. This requires that all magnets and relays are
functioning correctly, and there is precision in their
positioning.
The next figure shows a representation of the lid, body,
magnet, and relays. There are two magnets on the lid
and two sets of relays on the body.
