| | 2 | 1) Get used to the suppliers for materials that are usually used, some of which are listed below. Mentors usually order parts for students during the hectic 6 week build season. Many of the parts in stock are the related to the FIRST FRC supplier site, AndyMark. Every year we get a "Kit of Parts" for the robot build once the competition is announced. It includes dc motors called CIMS (pronounced "sims") as well as competition-specific parts. |

| | 4 | i) AndyMark.com supplies many of the standard parts for FIRST FRC robotics |
| | 5 | ii) Chief Delphi is the site with user forums for FIRST. It is very useful when you want to know what has been tried before or have questions in the current competition. |
| | 6 | iii) During the build season you are often limited by time to order only from places that can ship in a day or two and local hardware stores. The main quick suppliers are often McMasterCarr.com or Amazon.com. Andymark is slow, but you might be able to get it in two weeks during build season if you order early. |

| | 8 | 2) Get to know the status of CAD. Many students are learning measurement and fabrication. Producing CAD drawings can generally help students communicate ideas for parts, and can specifically help them specify how to fabricate a part. Although 2537 doesn't rely on it yet, some teams use CAD for the design and integration phase, similar to the professional engineers. Furthermore, all teams are required to turn in a CAD model of the robot. This doesn't have to be perfect, but of course there are other important reasons already to justify some CAD. The following programs are available free to students and mentors. |

| | 10 | i) Many students learn AutoDesk Inventor in the high school class "Intro. to Engineering Design." Some learn it well from that class, but don't learn it well enough to want to use it again, and others have no CAD experience. This program allows unlimited licenses for educational purposes. It is already installed in the computer lab, although it might be an old version. |
| | 11 | ii) Consider having them try a 2D CAD program if the 3D seems to advanced to start. We are currently trying out the free program called DraftSight, and are considering training students in it. |
| | 12 | iii) Solidworks is a popular professional CAD product that is available for free for FIRST FRC. Unfortunately they offer a limited number of licenses. FIRST FRC uses this CAD program to build an virtual robot with control from the same software that is used in the real robot. |

| | 14 | 3) Realize that there is no perfect season, but that a good preseason can help students and mentors prepare. In my opinion the mech students should learn some physics terminology during this time. Most only take physics in their senior year, although many students do word problems in mathematics classes. To fill the gaps in preseason, Newton's equations with force and unit conversion should be taught in some way. It can help them understand concepts qualitatively, even if they don't use the equations, which is essential for effective technical discussions with peers and mentors. |
