Hypothesis

BackgroundWhat got us interested?

Why not use GPS?

What are the possible wireless localization methods?

Purpose and HypothesisThe purpose of this project is to determine the location of autonomous robots using the wireless signals (802.11 n).

We believe that the locations of the robots can be determined best using the Fingerprinting Method

MethodologyCreate a Grid-based layout

Take 10 scans of the RSSI signal

Repeat for every point mapped

ProblemsTime consuming

Fluctuating wireless signals

Not as accurate as expected

Questions

ResultsWe were able to locate the robots through WiFi signals using the Fingerprint method.

We were able to develop heat maps showing the areas where signal strength is greatest.

Created programming algorithm that allows the robots to autonomously navigate to a single relative location.

ConclusionThe location of devices are able to be located using wireless signals.

An open area would be ideal because objects absorb the signals.

A consistent transmit power should be used to improve accuracy.
