Re: Intermittent connection on field only

First has a serious problem with dead robots on the field. The radio power supply and cabling has known issues. Given the severity of this problem and most likely there are many points of failure all points need to be looked at. The power supply issue needs to be looked at closely to see if there are problems other than cabling. I mentioned that there are potential problems with a switching power supply feeding a switching power supply feeding a switching power supply. I have never head of anybody that has characterized the load dump and switching transients on the PD. Does this affect the power supply to the radio? One transient that gets through is all that is needed to potentially lock up the radio electronics. It would be a very good idea to get some real on the field data. This needs to be done at a competition. A competition like Monty Madness should be RF noisy enough to put the radio into a high power state. ( gain scheduling) Team 1640 will be at Monty. We would be willing to have data logging put on to our robot. Can't load code on our c-rio. It's busy enough. Has to be stand alone. We have a swerve drive using 8 motors plus 4 more motors for ball handling and shooting. Should be a good heavy load environment for some testing. The testing should be able to see short transients. So if this want to be done our robot is available. Contact me if our robot is needed.
