Re: Possible FLR Hacking?

I'm curious about the monitoring of errored packets and intermittent loss of connection.

Is that information categorized in the FMS by team number?

I think it would be nice to know if bad D-Link placement was giving some teams a significant disadvantage.

Since radio is essential to control and control is essential to safety. One might argue that radio functionality on the robot should pass some hurdle as part of robot inspection.

Team 241 had intermittent control problems at GSR- we were looking to blaming our own software or use of the CAN with the Jaguars or other things- it was only after the competition was over that we thought of actually moving our D-Link to a more radio signal friendly position on the robot.

If the problems don't show up at home base or in the pits or on the practice field, but show up on the competition field, it can be quite maddening. The problems seemed minimal on Thursday but got worse on Friday and Saturday.

As to robots moving and the joysticks not: it sounds to me that MotoSafety and/or watchdogs might be set to very long times( or removed) and connection to the DS was lost (or software took a long circuitous run through a loop).
