Re: What do you think of the jaguars?

We had no problems during our build season or regional but at the second to last game in the championship we blew 2 jags at the same time... but there's a solution!

From what I understood from the guys from micro-whatever's booth in the pits, the driver gate was destroyed most likely due to static electricity backlash from the driving motors to the speed controller. caused probably because of the playing field (plastic wheels and plastic flooring) - because the robots weren't grounded to the floor, during a collision between a statically charged robot and an uncharged robot, the current might have gone back to the jaguar melting the drive gate.

If that really is the problem (supported by the statistics from utlinebacker's posted report), it can be easily fixed by adding a grounding rework from the robot. i.e. get a small wire, exposed on both ends, attach a connector to one side, bolt the connector to your chassis and let the exposed end be dragged on the field - similar to most cars. (even a small gauge wire would do the trick) And all the static charge will be immediately grounded.

However, for this to work, ALL teams must use that, otherwise even a grounded robot could be shocked by an ungrounded, charged robot. And although I find it hard to believe regolith is gonna be used next year as well, it's a good idea to do that anyways. just as a safe measure.
