1. NIMS Localization Andrea Coba Joshua Nogales Andre Encarnacao Akhi Singhania

2. 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.

3.  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 Check List

5. Data Gathered Velocity 1Velocity 2 Velocity 4Velocity 5

6. Problems & Solutions  Bumps due to high acceleration  Use normal acceleration  Sensor transition time from 5 to 0 Volts  Can only have sensor detect when moving slowly  Errors due to serial and ADC connections  Error checking in programs  NIMS small distance inaccuracies  Change algorithm for detecting

7. What next?  Create automated calibration program  Finalize algorithm  Right Triangle Test  Deployment at UCLA

8. 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.
