Part 1 | 5 Gracious Professionalism® - “Doing your best work while treating others with respect and kindness - It’s what makes FIRST, first.” Introduction What is FIRST® Tech Challenge? FIRST® Tech Challenge is a student-centered program that focuses on giving students a unique and stimulating experience. Each year, teams engage in a new game where they design, build, test, and program autonomous and driver operated robots that must perform a series of tasks. To learn more about FIRST® Tech Challenge and other FIRST® Programs, visit www.firstinspires.org. FIRST Core Values We express the FIRST® philosophies of Gracious Professionalism® and Coopertition® through our Core Values: • Discovery: We explore new skills and ideas. • Innovation: We use creativity and persistence to solve problems. • Impact: We apply what we learn to improve our world. • Inclusion: We respect each other and embrace our differences. • Teamwork: We are stronger when we work together. • Fun: We enjoy and celebrate what we do! Gracious Professionalism® FIRST® uses this term to describe our programs’ intent. Gracious Professionalism® is a way of doing things that encourages high-quality work, emphasizes the value of others, and respects individuals and the community. Watch Dr. Woodie Flowers explain Gracious Professionalism in this short video. 6 | FIRST® Tech Challenge Basic ‘Bot Guide for REV Part 1 Revision 1.2: 07.02.2019 Introduction to the Guide Introduction The Basic ‘Bot Guide is designed to be a resource for teams looking for step-by-step instructional for building the basic chassis and structure needed in a FIRST Tech Challenge competition. There are multiple versions of this guide, previously called the “Push Bot Guide”, this version the Basic ‘Bot Guide for REV has been created to use the new and differing parts in the 2019-2020 season’s REV kit of parts. Parts • Rev FTC Competition Set • Electronics Modules and Sensors Set • Control & Communication Set 1 or 2 • (Optional) Only the tools included in the FTC Competition Set will be needed to build the chassis. The screws and nuts are a standard size and having more tools may allow more students to participate at the same time. • (Optional) A ruler is not needed to build this robot, but it is necessary to make sure that the robot is competition ready. Tips and Tricks • Secure the screws/nuts just enough, so parts do not slide/move relative to each other. Overtightening the screws will damage the aluminum extrusions. • Make sure that set screws are installed in every axle hub, motor hub, and axle collar. • Refer to the legend provided in the Kit of Parts, if any parts are unfamiliar. • Make sure that all assemblies are square. It is hard to drive a crooked robot straight! • The drive wheels are powered by two DC motors, which are relatively heavy. The drive wheels are on the back of the robot, because that is where the most weight is. This weight is needed to help the wheels grip the surface better. • Omni wheels are on the front of the robot, which allows the robot to turn more easily. The omni wheels can slide sideways with very little friction due to the rollers. Unless otherwise noted, the top image in each step shows the necessary parts; the lower image shows the completed assembly.
