Signal Reception Tester

A normal transmitter's antenna can be oriented in many different ways, which can vary the signal reception. In order to quantify the best possible orientation of the transmitter, we built a rotational device that is capable of rotating the transmitter around 2 axes.This allows for the testing of the signal reception strength at each orientation and ascertain the best possible position to mount a transmitter.

Steps to run the test on Linux:

  • Download nxt-python and its required libraries from http://code.google.com/p/nxt-python/
  • Plug the NXT brick into your computer with a USB cable.
  • Run the modified pip-sense program to start collecting samples.
  • Run the python script.
  • Once the test is complete, turn off the NXT, get both data files, and put them in a directory where MATLAB can use them.
  • Then run the m-file to plot the data.
