We have been trying to trace down some problems that we have encountered and other teams have related to us. I am sure that IFI is working on them too. It seems that on occasion a series of corrupt data packets get through. What effect this has is not clear yet because it does not always cripple communications. It seems that the modem, once it has lost handshake, will take a indefinite amount of time to relock. Of course, if you reset the robot controller it occurs quickly, but most of us can't run out onto the field during a match to reset the robot. I am suspecting an interaction between the radio modems and other radios. I would like to suggest to IFI to perform some hard testing with walkie talkies in close proximity to the control system. I am taking the side of RF interference causing distortion in the RF deck of the modem simply because I am more familiar with that type of interference. I have no hard evidence either way on this issue but will fill you in when we have something definite.
