OK..back in action. After Hurricane Wilma came
didn't have any electricity, or phone service so I was
unable to post an update. So now that things are returning
to normal, I can continue with UltraMega.
I was able to mount the bump sensors on the chassis,
seems like it will work fine. I am using a strip of
transparent vinyl tubing with the music wire inserted
The tubing is wrapped around the front of the chassis, and
also covers the left and right sides for the front end.
The internal wire will be connected to ground, and small
strips of wire inserted through the tubing will be the
Normally Closed (NC) contact, of the bump switches.
Tinkering, and some rudimentary testing yielded successful
results, as the music wire created a spring-like effect, and
the tubing allowed some shock absorbtion.
When I am done with mounting the assembly, I will be
connecting it up to the debounce cct, and testing the
response. The schmitt trigger ICs should clean up the
signal also, which will be sent to the interrupts of the
AVR. The microswitches will also be added, but I am still
noodling their correct placement.
I have also moved the IR sensors up to the 2nd deck.
left and right sensors are positioned to detect objects
within their respective field of views. The front sensor is
mounted on a stepper motor that will scan the "blind spots"
of the left/right sensors.
An updated schematic, and pics will be added to the site
soon. Stay tuned....Peace!
