Re: InfraRed Problem

My team has been discussing this problem with the IR sensor recently. We have discovered that at any distance remotes will interfere and interrupt the recievers. This causers the IR sensor to not receive any signal from the remote trained to it. This can cause problems at competitions.

Another problem that we are discussing is LOS (Line of Sight). We have found that our robot does not recieve very good signal if any unless the remote is focused directly on the IR sensorboard. Only having 1 Robocoach i think could complicate the matter. Right now our team is contemplating giving our robot the ability to strafe so that it will be facing one direction during the entire Hybrid period.

Another issue on the IR is focusing the reception and output from the remote. Some examples of this might be a cone or some sort of funnel on the IR sensor or the remote. We have attempted to prototype this with our IR board and remote but we have not had much success. We have found that either it makes no difference or it limits the LOS of the robot making it harder to keep the signal reception.

One other thing... Earlier there was mentioned frequencies of IR and hopefully getting a different frequency so that you are not jammed or jamming your oponents. The problem with this is that IR has protocol but not really frequency unless you are on a different wavelength. This would cause any IR to recieve interference from a strong light source/ IR source (we even have had problems outside in the daylight).

If anyone has any ideas on how to eliminate interruption and/or focusing the IR signal that would really help my team out.
