Team 1983 has adopted a very similar approach this year. Everything you have looks very necessary, and very close to what we have done. We completely took the idea and ran with it. We have a 5 stage checklist that goes through multiple team members to get the ok for a match. Since we started fully using this system, we have almost eliminated pre-match problems of things being overlooked. It has proved very efficient for us. I believe our checklist is in the white papers section as part of our safety plan. I will double check, and edit if not, but I'm assuming it is there. => scratch that, the entire plan, for example how we use the checklist can be found in the white papers under the Skunkworks 1983 Safety and Health Plan, and the appendices, including the actual safety checklist (Appendix A) can be found on our website
www.ahsrobotics.us.
Anyways, this has proved a very very good thing for our team this year.
