Recap of previous presentation

Current method of locating the NIMS node is extremely time
consuming.

Our job is to find a method which automates the current
process, making it more efficient and accurate.

We decided upon using a reflectivity sensor which will be
attached to the shuttle and pieces of black gaffer tape which
will be on the static cable.

The sensor responds to the gaffer tape, so we will find the
nodes location by writing an algorithm that will use the sensors’
output when it comes near a piece of tape, as the shuttle
traverses the static cable.
Check List

Installed the analog to digital
converter and learned how to use it.

Attached the sensor to the shuttle
and performed tests.

Created Python program to detect
tape and output various data and in
different manners
Data Gathered
Velocity 1
Velocity 2
Velocity 4
Velocity 5
Problems & Solutions

Bumps due to high acceleration


Sensor transition time from 5 to 0 Volts


Can only have sensor detect when moving slowly
Errors due to serial and ADC connections


Use normal acceleration
Error checking in programs
NIMS small distance inaccuracies

Change algorithm for detecting
What next?
 Create automated calibration program
 Finalize algorithm
 Right Triangle Test
 Deployment at UCLA
Big Picture

We are providing an automated
solution for locating the NIMS Node
accurately.

Will in turn make it possible for NIMS
to perform data sampling much faster
and easier

And therefore, helps CENS achieve
their vision of pervasive monitoring
of environments.
