Perhaps a little history and experience here would help...
The nature of the game has led to some teams using unusual designs to launch the ball. While most teams design in some form of safety locks or other actuation devices, when needed, other teams do not. This year, far more teams are using pneumatics than in past years. Many of those teams have no experience with pneumatics and have no mentors who use them in daily work. The same is true for springs and other deformed robot parts and yes chains and sprockets. While many of you do not remember the safety warnings of past years, I can tell you they were there. Robot inspectors find unusual mechanisms every week so it is not possible to make a statement about one that covers all mechanisms. Most teams that have experience with the actuating parts they are using, know how to design in safety to prevent any harm to participants and to volunteers. If you are one of those teams that has been unable to design a mechanism that can be safely carried to the field and will not accidentally release when touched by a student or volunteer or by a robot inspector, then plan to be asked to add something to prevent this occurring. There are a number of ways to accomplish this and the Inspectors will assist you. I am sorry if this produces a little stress for you or your team. There have been minor injuries this season and at least one unexpected release where the lock prevented an injury.
Even the team may not be aware of the danger that lurks within. If you have never been in the queue waiting to take the field, then don't ask me to explain how dangerous it can be.

Please remember that boy and girl scouts, FLL and FTC students, parents and grand parents, little children and non-technical folks will be roaming the pits and assisting with the field in every venue including the Championship. They have to be protected as well.
