Re: Official Beacon Tracking Code Posted
Hi,
We began experimenting with the IR sensors. We're waiting on our mechanics to get the robot assembled so we can wire it and begin to tweak the code.

The beacon works well...looks cool through a digital camera set to night vision. We are using an IR sensor to drive an LED. Tapping off signal between 33 ohm resistor and LED cathode and sending to oscilloscope.

We are curious about the IR sensitivity. About 12 feet from beacon we realize how sensitive the IR sensors are in terms of orientation (azimuth and elevation). We placed a tube around the sensor to improve detection. Turning lighting off in room seems to improve signal detection...however, this may simply be allowing us to see the waveform a little better.

Has anyone experimented with improving detection range? Other than optics of some sort, there is no way to amplify the signal inside the IR sensor since an ON/OFF signal is produced.

Regards,
ChuckB
