Re: pre-charged Pneumatics

Eagle,
It would seem that a simple application of surgical tubing in front of the kicker in your example would prevent it from extending beyond the FRAME PERIMETER and still allow sizing with the kicker in the fired (non-deflected) state. This is the requirement we used in your first year although only one or two robots used a system like this in Minnesota that year. As I remember it was one of the Cat teams who had discussed this with me prior to the regional and had it corrected by the time they were inspected. This is also an excellent example of Mike's previous post about needing a locking pin to hold the mechanism in place while moving the robot to the field. Although for the life of me, I cannot see a good reason that a team would need to pre charge this device before a match begins unless it takes many seconds to charge. The safety to students and field personnel in the event of an accidental discharge staggers the imagination.
