= Pit Design The pit lives primarily for 2 reasons: 1. to serve as the pit, where the robot is parked and repaired 2. to serve as a hub for the team, to perform outreach and marketing == The Physical Pit '''!Requirements/Considerations'''[[BR]] * all items brought must fit inside the pit (no items sprawling out) * there will (probably) be a table you can't remove * safe and effective working condition * items should be accessible * subteams should ideally store their items in a place where they won't run into each other as they do things in the pit * display of sponsors, other outreach/marketing items '''Constraints:'''[[BR]] * dimensions * technically a 10'x10' space, but usually 9'x9', and sometimes 8'x8'; a good design will work in as small as 8'x8' but not be constraining in a 10'x10' space * nominal height limits set by venue, but usually ~10' * electrical power: there is usually a limit per team and a limit per 6 teams at district competitions * cannot daisy chain (power strip + power strip) {{{#!div style="border: 1pt dashed; color:blue" '''"What are all the things you need to bring to the pit?"''' From that list, think about how might you ''most conveniently'' * store '''each item''' in the pit * access/display '''each item''' in the pit * transport '''each item''' As with all iterative engineering, ask '''"How can we do better?" }}} === Things to Think About '''Questions to Ask Yourself'''[[BR]] * What is the workflow of each match cycle? Will people bump into each other as they crowd around the same spot where batteries and bumpers are stored? * What if you get a corner spot? Are two sides open or just one? * What do you do with all the jackets and bags team members will bring? * What to do with stuff other teams give you? == People in the Pit Everyone who's in the pit should have something to do. Everyone who's there should understand what they're responsible for and when. For example, * Billy Joe Fisher : responsible for replacing the battery before each match * Ellen B. Evergales : in charge of pit operations; has the authority to kick out people who aren't doing anything if space is crowded * Alai Suetterl : performs checkup of robot immediately after each match * Dan R. Campbell : reads off items on the pre-match checklist and ensures each item is completed {{{#!div style="border:1pt dotted; color:red" For every match cycle, the robot will need to be examined. To ensure that all items are checked, you should really use a '''checklist''' of items to check. {{{#!div style="1pt dotted; color:orange" '''Qualities of a Good Checklist'''[[BR]] * detailed and precise enough that someone else could take over if needed * broken up into individual tests of specific things * don't say "check all connections", but "tighten bolts on arm-shooter connection" }}} When you carry out the checklist, there should be at least 2 people. One person reads off each item from the checklist; the other ''actually'' performs each check. Ideally, a third person can double check each item's completion. }}} == Practice 1. Practice setting up the pit, especially if it's complicated. * you can check you have all the parts/tools necessary * people can get a feel for how the pit will be run 2. Assign roles beforehand, make sure each person understands their role = Current Pit Design & Components ?? ?? = Previous Pit Components ''(listed in reverse-chronological order)'' These are just the previously used items. ''There are definitely better solutions out there.'' == curved trade show display A 10 ft. long curved display structure with soft material backing (allows velcro attachment). === PROS * easy to attach anything with velcro * somewhat flexible in where it is placed * hollow space inside in which to hide things * single carrying case === CONS * large, unwieldy setup, esp. if not practiced beforehand * expansion of the inner frame can take a good bit of space * very tricky to assembly correctly (such that it ''stays'' assembled) == steel & wood carts === PROS * simple * wheels === CONS * extremely heavy (some places dangerous) * require a trailer (or similar) to transport == cube frame A 9 ft. cube made of 16 aluminum frame pieces and 16 pairs of fasteners. === PROS * simple * enables hanging of elements from any segment === CONS * separate and heavy parts * restricted to a 9' cube (some other configurations possible, see below) === Other Configurations It is possible to have a few other configurations of the frame besides a 9' cube, although they are still just as (or more) constraining. * remove one side * lower entire frame by 1/2 (and remove front side) * use only 3 sides (one corner) == pvc pipe frame A modular frame of PVC elements. === PROS * easily sourced, easily assembled * lightweight === CONS * looks much less professional
